Foam concrete is a kind of concrete with lightweight and has ideal strength. Because of the hollow structure in foam concrete, it has the function of absorbing heat and isolating sound.
The density of foamed concrete is 300-1200 kg/m3, and the thermal conductivity is between 0.08-0.3W/ (m ·K).
Foam concrete is widely used in CLC blocks, lightweight partition panels, roof insulation, floor cushion construction, floor heating backfilling, and other occasions.
At the same time, foam concrete is also a good sound absorption material, which can be used in highway sound insulation boards, sound absorption boards, and other fields.
Generally speaking, foam concrete is a kind of building material with multi-function, environmental protection, and economy, which has a wide application prospect.

Concrete water-reducing admixture is a chemical additive that is often added to concrete to reduce the heat of hydration of the concrete and to improve the ductility and fluidity of the concrete.
Water-reducing agents can save cement usage and reduce production costs while maintaining the strength of concrete.
Under the condition of keeping the water consumption and water-cement ratio unchanged, the water-reducing agent can increase the fluidity of concrete, making the concrete easier to process and construct.
Water-reducing admixtures can reduce the water-cement ratio of concrete, thereby increasing the strength of concrete.
Water reducing agents can improve a series of physical and chemical properties of concrete, such as impermeability, frost resistance, erosion resistance, etc., and improve the durability of concrete.

He emphasized that concrete admixtures not only enhance the performance of concrete, but also improve the durabaility and safety of bridges.
Roger Luo pointed out that concrete admixtures can significantly improve the fluidity, strength and durability of concrete. These admixtures include water reducing agents, retarders, air entraining agents, antifreeze agents, etc. They can be mixed with raw materials such as cement and aggregate during the concrete preparation process to optimize the performance of the concrete.
In the construction of concrete bridges, the application of concrete admixtures can bring many benefits. First of all, water-reducing agents can reduce the water-cement ratio of concrete and improve the strength and durability of concrete. Secondly, retarders can extend the setting time of concrete, allowing the concrete to flow and compact better after pouring. In addition, air-entraining agents can form tiny bubbles in concrete to improve the frost resistance and impermeability of concrete. Finally, antifreeze agents can improve the frost resistance of concrete in low-temperature environments and ensure that bridges can maintain stable performance in cold areas.
According to multiple media reports, on June 4, local time, the Agwani-Sultanganj Bridge across the Ganges River under construction in Bihar, India, collapsed again after it collapsed last year. Witnesses at the scene captured footage of the bridge collapse, and authorities said no one was injured or injured in the accident.
It is reported that Bihar Chief Minister Nitish Kumar admitted that the bridge had design flaws, ordered an investigation into the collapse, and asked to find the person responsible for the incident. It is understood that the bridge cost 17.1 billion rupees (approximately 1.47 billion yuan), has a total length of 3.1 kilometers, and was originally expected to be completed around November to December this year. Russian media said the bridge collapsed again, raising questions about the quality of construction materials. Indian media said this incident triggered discussions about corruption in India.
It is worth noting that just two days before the bridge collapsed, on June 2, "India's deadliest train accident in recent years" occurred in the eastern Indian state of Odisha, causing thousands of casualties. Indian authorities said a preliminary investigation showed that a signal problem in the electronic interlocking system caused the accident. It is reported that the railway where the accident occurred is crucial for Indian migrant workers, who usually come from the poorer eastern and central regions of India and must take cheap trains to work in more developed southern cities.
If the Agwani-Sultanganj Bridge is completed, it will reduce cross-regional travel time, alleviate traffic congestion, and make the region more closely connected. For this reason, the bridge is very important to Bihar. However, the bridge collapsed within seconds amid a rumble on June 4.
After the incident, Kumar said that the matter would be investigated and the person responsible for the incident was found. However, according to Indian media reports, Bihar Deputy Chief Minister Yadawan said the collapse was a "planned demolition." According to Yadawan, after heavy rains caused part of the bridge to collapse last year, the government assigned researchers from the IIT-Roorkee Institute, which specializes in the construction industry, to analyze the structure of the bridge. "Although the final analysis results are not yet available, experts have told us that the bridge's structure has serious flaws." Officials from the Road Construction Ministry added that the government did not want to risk waiting for the final report to demolish the "defective" bridge.
It is reported that this is not the first bridge collapse in India. At the end of October last year, a century-old suspension bridge in Morbi, Gujarat, western India, suddenly broke, killing hundreds of people. Later, it was reported that the bridge's maintenance contractor was a group specializing in watches and lighting fixtures, and a small, unknown company did the actual maintenance work. (Related reports: Behind the death of 141 people when a bridge collapsed in India: Was the bridge repair contractor a watch manufacturer?) The Indian media pointed out that the bridge collapse exposed the country's infrastructure vulnerabilities that cannot be ignored. They once again exposed India's extreme lack of public management. Capacity of venue for large crowds.
Just two days before the collapse of the Agwani-Sultanganj Bridge, "India's deadliest train accident in recent years" occurred in India, which undoubtedly focused the attention of all walks of life on the issue of railway traffic safety in India.
"India's deadliest train accident in recent years" occurred in the eastern Indian state of Odisha.
As one of the largest railway systems in the world, India's national railway network is approximately 64,000 kilometers, carrying tens of millions of passengers daily. Over the past few years, India has also been vigorously expanding and building its domestic infrastructure, especially the railway industry, in a costly manner. Data show that in the last fiscal year, the Indian government spent nearly $30 billion on the country's railway system, an increase of 15% from the previous year. The World Bank also pointed out in a report in April that the Indian government's expenditures to achieve long-term goals have increased compared with before the outbreak, especially in infrastructure construction including railway networks. According to Indian Railways Minister Vishnu, approximately 5,200 kilometers of new railways were laid last year.
At the same time, the country's spending on basic maintenance of rail tracks and other safety measures has been falling. According to a report released by an independent Indian agency last year, the government allocated less money for track maintenance and renewal, and officials did not even spend it all. In addition, India has a specific fund dedicated to renewing and maintaining railway tracks, etc., and the budget was reduced by nearly a quarter during 2017-2021.
It is reported that since Indian Prime Minister Modi took office in 2014, the country has taken an important step in the safety of train operations. India has also developed a local automatic train protection (ATP) system - kavach, to improve the safety of train operations. It is understood that the cost incurred so far in developing kavach amounts to Rs 16.88 million. As part of Modi's "self-reliant India" plan, the system has been applied to 2,000 kilometers of lines in India, accounting for less than 4% of India's total railway length. However, a spokesman for the Indian Railways said that the system was not applied on the line where the accident occurred.

Concrete buildings play an extremely important role in modern society. They are the main shaper of our urban appearance and the witness of economic development and social progress. Whether it is a towering skyscraper or a warm and comfortable residential area, whether it is a solemn public facility or a unique artistic building, concrete plays an indispensable role in it.
Concrete admixtures are equally important in the construction of concrete buildings. Although these chemicals or mixtures only account for a small proportion of the total volume of concrete, they have a significant impact on the performance and characteristics of concrete.
The Middle East has more than 20 of the world's tallest buildings, including 12 in Dubai alone, one of which is the tallest.
At 828 meters tall, the Burj Khalifa is taller than the Empire State Building and Willis Tower, making it the tallest building on earth.
Opened in 2010, this mixed-use megastructure is the centerpiece of a new mixed-use development in downtown Dubai.
This is also very symbolic. The Dubai government hopes to expand its economic scale. The key to making Dubai an entertainment center in the Middle East is to obtain the title "the tallest building in the world."
Scientific research on tall buildings has progressed slowly for decades, but the completion of the Burj Khalifa represents a giant leap forward in this field.
Philip Oldfield, School of Built Environment, University of New South Wales:
"The uniqueness of the Burj Khalifa lies in its shape and appearance. It is designed and optimized to resist wind and shock absorption. The floors on different floors are built into non-parallel structures. This design can ensure that when strong winds strike, The vortex generated at the back of the building will spread to different floors, and the time and floor of the action are not fixed, preventing the building from shaking back and forth."
The Y-shaped tower forms three wings, adding to the building's stability.
The construction team faced huge challenges when building in the sand and heat of Dubai's desert.
Virginia Tech architect Stephen Eyre:
"Because there is no bedrock in the desert, the engineering team must rely on friction to build the foundation, driving very deep piles in the sand. Another question is how to prevent the concrete from quickly Pumping to the top of the building while it solidifies?"
In this case, engineers invented a mixture containing ice flakes to keep the cement cool enough.
Dubai has become a popular tourist destination today due to the Burj Khalifa.
Dubai is now considered the most popular tourist destination in the world. Its shopping malls are high-end and luxurious, its luxury hotels and resorts are extremely prestigious, its beaches are pure and pollution-free, its nights are vibrant, and its architecture is magnificent. The entire country is world-famous.
Jason Barr, professor of economics at Rutgers University-Newark:
"Thousands of tourists come to Dubai and go to observation decks. Across the world, whether in Dubai, Chinese Taipei, or Shanghai, observation decks are a powerful motivation for building super high-rise buildings because they are a 'money-making tool'. '"
More than a decade after its construction, the Burj Khalifa remains the tallest building in the world, but how long can this record remain?
Jeddah, Saudi Arabia, plans to build the world's first 1,000-meter-tall building, the Jeddah Tower, which has already completed 38 floors. Saudi Prince Alwaleed hopes to replicate the Dubai model in his own country.
Jeddah, Saudi Arabia, was supposed to be a futuristic metropolis, home to a new "world's tallest building" and attracting tourists.
Construction work on the Jeddah Tower began in 2013, but the project has stalled.
Virginia Tech architect Stephen Eyre:
"When the foundation was laid and only one-third of the building structure was built, there was a regime change in Saudi Arabia, and construction has been suspended since then. Only about one-third of the project is left, but the start time Is still unknown."
There still needs to be sign of work resuming on the Jeddah Tower. What will be the future fate of this skyscraper?
Jason Barr, professor of economics at Rutgers University-Newark:
"Today, the majority of the world's population lives in cities. This number continues to rise. As more people settle in cities and economies develop, buildings will accommodate more people on the same land area. People. Fundamentally, skyscrapers are a response to urbanization."
Philip Oldfield, School of Built Environment, University of New South Wales:
"Theoretically, using traditional techniques and high-performance steel and concrete as building materials, we can build a 2,500-meter-high skyscraper. But the key question is, should we do this?"
The carbon dioxide released during the construction, use and demolition of buildings accounts for 37% of total human carbon emissions. This is a huge number.
For example, using concrete accounts for 8% of total CO2 emissions. Therefore, we should consider how to build skyscrapers more sustainably.
Virginia Tech architect Stephen Eyre:
"In our lifetime, we will have to wait and see whether humans will build a skyscraper taller than the Burj Khalifa. This is what all humans have been doing. A long time ago, humans piled stones one by one to build Stonehenge, then the early pyramids, then the Eiffel Tower, and now the Burj Khalifa. I believe we will continue to strive towards the heights of heaven."

Recently, many parents of students in the UK have been very upset.
School is about to start in the next few days, but on Thursday, the British Ministry of Education suddenly ordered the closure of 104 schools because of "dangerous buildings" in those schools.
The buildings of these schools all use a building material called Reinforced Autoclaved Aerated Concrete (RAAC), a lightweight, air-cement-like material often used as a cheaper alternative to concrete.
(Reinforced autoclaved aerated concrete material)
The inside of the material is like a chocolate bar snack with a honeycomb structure.
This material was widely used in the construction industry in the second half of the last century.
However, over time, it was discovered that the structural integrity of this material would be lost when moisture penetrated, and its service life was only 30 years.
In other words, many houses built with it are no longer safe.
(This material collapses)
For many years, the safety issues of reinforced autoclaved aerated concrete have been ignored.
It was not until 2018 that the reinforced autoclaved aerated concrete roof of a primary school in Kent collapsed, which attracted the attention of the Ministry of Education, which began to investigate the safety hazards of this material.
(The roof of a primary school collapsed in Kent in 2018)
Last year, the Department for Education organized a survey to determine how the material was used in schools.
Survey results in June showed that 572 schools in the UK may have used reinforced autoclaved aerated concrete in their school buildings and that school buildings with 700,000 students "need to be rebuilt."
(Roofs using this material collapsed)
Currently, 156 schools have been identified as using this material, 52 of which have taken remedial measures and do not need to be closed. The remaining 104 have been ordered to be closed by the Ministry of Education.
(A school cordoned off areas with safety risks)
These schools require temporary or long-term renovation work and may be closed for as little as a day or as long as several months.
For example, one school renovated a corridor using this material, which would affect access to the library and gymnasium. However, the project was simple and the start of school was only delayed by one day.
However, the Ministry of Education also said that "a small number of schools" had to be "fully or partially relocated."
For example, during the weeks when the school building is being renovated, students can take classes at nearby schools, community centers, and vacant office buildings.
The Ministry of Education told parents that most schools will not be affected and children can still attend school as usual in September.
Online classes, such as those organized during the COVID-19 epidemic, will be used as a last resort and will only be conducted briefly. Face-to-face teaching will still be possible as much as possible.
However, due to "operational reasons," the Ministry of Education did not disclose the specific school list, which caused parents anxiety.
Parents and the media still need to complete an incomplete list of schools.
In the past two days, the Ministry of Education's order has caused a stir and has caused dissatisfaction among many British people, especially parents and schools.
Their anger is mainly directed at three aspects -
First, before the Ministry of Education took action, children had been attending classes in unsafe school buildings for a long time, which frightened parents.
Secondly, moving to other places for classes requires additional rent, and the government once said that schools should pay for it themselves.
After causing dissatisfaction with the school, they said the government would pay for it.
Finally, the Ministry of Education allowed schools to renovate their buildings during the past summer vacation so that students would not have to delay their studies.
However, the Ministry of Education did not act during the summer vacation, and the school was about to start again. Schools were suddenly asked to deal with such a complex issue, and the arrangements of students and parents were also disrupted.
A lot of people have been complaining about this online recently.
"Kids are going back to school in a few days! It's unbearable to have schools doing this now."
(Screenshot from X@Andrew_F_Smith)
"How long have our children been in danger in schools made of 'crumbling' concrete? When did the government know about it? What steps did they take? Did anyone notify parents that their children were in danger? OMG!! "
(Screenshot from X@JaneBurley22)
"My school, built in the 1950s, closed without notice in the 1970s due to safety concerns. I can't believe this is still going on."
(Screenshot from X@announcer_stef)
"They have six weeks to announce it and deal with it, but to wait until it's time to go back to school will cause more disruption to teaching."
(Screenshot from X@oszieuk)
Issues involving schools are just the beginning.
Even more troublesome is that many public buildings across the UK also use reinforced autoclaved aerated concrete, such as hospitals, courts, and police stations. These buildings also have safety hazards and face reconstruction problems.
(Reinforced autoclaved aerated concrete)
The material is used in more than 250 NHS hospital buildings in Scotland, and investigations are underway to establish the extent of the problem.
(This report mentioned that seven hospitals had safety hazards due to the use of this material and needed to be renovated)
Harrow Crown Court in north-west London has been closed indefinitely after the material was found to have been used.
(Harrow Royal Courts of Justice)
In the future, schools and some public buildings may have to be renovated. What is affected now is students, and more people may be affected in the future？
Concrete admixtures are chemicals added during the concrete preparation process to improve the properties and properties of concrete.
Concrete admixtures play an important role in improving the workability of concrete, adjusting the setting and hardening speed, improving physical and mechanical properties, improving durability and imparting special properties. This makes concrete admixtures increasingly widely used in the construction industry, which is of great significance for improving project quality, reducing labor intensity, shortening construction periods, and improving the durability and environmental protection of concrete.
