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.
CLC blocks(Cellular Lightweight Concrete) is a recently developed lightweight thermal insulation material. It is created by fully foaming a foaming agent through Zhongke equipment, mixing the resulting foam with cement slurry, and then carrying out cast-in-place construction or mold molding through the equipment's pumping system. This process creates a large number of closed pores within the concrete, which provide excellent insulation properties. CLC concrete is made up of two sets of organic binders mixed with foaming agents, cement, fly ash, stone powder, and other materials. These ingredients create a polymer with a continuous structure that contains uniform pores. This bubble-shaped thermal insulation material is ideal for use in roof insulation and slope finding, ground insulation cushioning, filling foundation pits with upturned beams, and wall pouring. The closed foam holes created within the concrete make it lightweight and great for insulation. Overall, CLC concrete is an energy-saving material that provides excellent insulation properties, making it a popular choice for a variety of construction applications.
CLC concrete is usually a kind of porous material made by mechanically preparing foam agent aqueous solution into foam, adding foam into the slurry consisting of siliceous materials, calcareous materials, water and various additives, and then mixing, casting, molding and curing. Due to the large number of enclosed pores in CLC concrete, it has the following good physical and mechanical properties.
The density of CLC concrete is small, and the density grade is generally 300-1800kg/m3. The density grade of commonly used CLC concrete is 300-1200 kg/m3. In recent years, Ultralight foam concrete with a density of 160kg/m3 is also used as CLC concrete. Because of the low density of foam concrete, the use of this material in building structures such as external and internal walls, layers, floors and columns can generally reduce the dead weight of buildings by approximately 25%, and some of them can reach 30% -40% of the total weight of structures. Moreover, for structural components, using CLC concrete instead of ordinary concrete can improve the load-bearing capacity of the component. Therefore, using CLC concrete in construction projects has significant economic benefits. Especially in the recent "Eleventh Five Year Plan", the "Medium and Long Term Energy Conservation Special Plan" has set specific goals for the domestic construction industry to achieve energy conservation, with an increase in the energy-saving standard coefficient to 65%. Make the market potential for building energy efficiency enormous.
Due to the presence of a large number of closed small pores in CLC concrete, it has good thermal performance, i.e., good insulation and insulation performance, which is not possessed by ordinary concrete. Normally, CLC concrete with a density grade ranging from 300 to 1200 kg/m3 has a thermal conductivity coefficient between 0.08 and 0.3w/(m · K) and a thermal resistance approximately 10-20 times that of ordinary concrete. The use of CLC concrete as a building wall and roof material has good energy-saving effects.
CLC concrete is a porous material. Therefore it is also a good soundproofing material. It can be used as a soundproofing layer on the floors of buildings, soundproofing panels on highways, and on top floors of underground buildings. Foam concrete is an inorganic material and will not burn, so it has good fire resistance. When used on buildings, it can improve the fire resistance of buildings.
CLC concrete can be poured on-site for construction, closely combined with the main project.
The porosity of CLC concrete gives it a low elastic modulus, which enables it to have good absorption and dispersion effects on impact loads.
Cast-in-situ CLC concrete has a low water absorption rate, relatively independent closed bubbles, and good integrity, making it have a certain degree of waterproof performance.
CLC shaped concrete can not only be produced into different products in the factory but also be used for on-site construction, directly pouring into roofs, floors, and walls.
The raw materials required for CLC concrete are cement and foaming agents, which are neutral and do not include harmful substances such as formaldehyde and benzene, avoiding environmental pollution and fire hazards.
Simply use a cement foaming machine to achieve automated operation, which can pump long-distance transportation with a vertical height of 200 meters. The workload is 150-300 cubic meters per working day.
The application range of CLC concrete is wide, and the following are specific application areas:
Thermal insulation: Due to the advantages of lightweight, high-strength, and energy-saving, CLC concrete is widely used in energy-saving materials such as roof insulation and slope finding, ground insulation and cushion layer, upper beam foundation pit filling, and wall pouring. It belongs to bubble shaped thermal insulation material and is characterized by forming closed foam holes in the concrete to make the concrete lightweight and heat insulation.
Architecture: CLC concrete can be used to replace traditional building structural materials such as wood and steel. It is suitable for the production of components such as floors, walls, and roof panels in prefabricated buildings, and has advantages such as environmental protection, energy conservation, high strength, and lightweight. In addition, it can also be used to make building decoration materials such as partition boards and stairs.
Other fields. CLC concrete can also be used in the production of waterproof rolls, external wall insulation boards, and other materials, as well as in projects such as highway embankments and airport runways.
The autoclave-free production technology does not use an autoclaved steamer, and the aerated block of the same quality and strength can reduce costs but also reduce the reduction. It is a new type of energy-saving and environmentally friendly production technology that is widely used in assembly environments. The cost of block-free is mainly used for the amount of cement added. In production, the amount of cement cannot be reduced to reduce the cost. Otherwise, it will affect the quality of the product.

Cement foaming machine, also known as foam generator, is a machine that makes cement foaming agent into foam. Is the machine that can make foam the cement foaming machine? the answer is negative. If you just want to make foam, there are many ways to achieve it, such as mechanical stirring. For example, in the early days, everyone directly added the foaming agent to the mixer to stir the foam, and there was also the use of a stirrer to stir the foam, but no one would stir it.
The device is said to be a foaming machine. There is also a blower blowing bubble, which can not be called a foaming machine, so it is not a foaming machine that can foam. In the past, the use of these two methods to make foam was very common, and only with the development of technology has a real cement foaming machine. Before purchasing a cement foaming machine, you must understand what a real cement foaming machine is.
Foam generator working principle is using the surface tension of liquid and the pressure difference of gas to produce foam. Under the action of liquid surface tension, the liquid forms a thin film, and the gas enters the liquid through a certain way, making the film break and form foam. As foam continue to rise toward the surface of the liquid, they will contact each other and form foam.
An important condition that can really be called a cement foaming machine is “it can be stably made into uniform, low moisture content and stable foam”.
The following is an introduction to the factors to be considered when purchasing a cement foaming machine:
The foam output of the cement foaming machine
The foam production of the cement foaming machine is an index to measure its efficiency. The foam production of the general cement foaming machine is 15m3/h, and the higher output is 30m3/h. Choosing a high-output cement foaming machine is not only to increase efficiency, but also to shorten the foaming time, reduce foam breakage during the mixing process, and reduce connected holes.
A good cement foaming machine also has a higher utilization rate of cement foaming agent. The higher the utilization rate of cement foaming agent, the more foaming agent will be saved. How to measure utilization? It is very simple, that is, by measuring the density of the produced foam under the same conditions, the lower the density, the lower the moisture content, and the higher the utilization rate of the cement foaming agent.
Generally, the foam produced is uniform, without connecting bubbles, and the stability of the foam with thick wall is good. On the contrary, the stability of the bubble is poor.
A good cement foaming machine is basically a "dumb" operation. There are still some models on the market that require artificial control of the water intake and air intake, and some even have additional meters, which looks very complicated, but in fact they are just fooling people.
Whether a machine is easy to use depends on whether the failure rate is low. How to reduce the failure rate actually depends on the conscience of the business, which requires the selection of good accessories. Take the air compressor used in the foaming machine as an example. A good air compressor with the same efficiency costs a few thousand yuan, while an ordinary one is only a few hundred yuan. The price difference is 10 times. Therefore, the choice of a machine with a low failure rate must depend on the pros and cons of the accessories and the reputation of the manufacturer.
See if there is after-sales service and later technical support. With good technical support and after-sales service, this has added value, which is not only buying a machine, but also technology. For a company with after-sales service, the quality must be reliable.

The introduction of Cement foaming agent:
Cement foaming agent refers to all the surface active substances whose solutions can be produced in large quantities through physical (stirring, compressed air, etc.) or chemical reactions under specific conditions. It is surface active, and the double-electron layer is arranged on the surface of the liquid film to inhale air to form bubbles, which are then composed of a single bubble.
1. Plant cement foaming agent
Plant-based plant fumigants mainly include soaps and saponins teas. They are the main source of refined smoking and oil absorbents. They do not contain pollutants, but smoked synthetic absorbents have more appearance than synthetic absorbents. In addition, the main component of these headphones comes from nerves, so they are classified as snorting nerve receptors.
The plant-based adsorbent uses high-quality natural plant polymer chemical materials as raw materials and is made through delicate and complex reactions. The product is pure and transparent oily fluid. It is not sensitive to hard water, non-toxic, tasteless, and has no sediment. PH neutral, dust-free cement, does not pollute the environment. The headset has no camera, is not easy to change, the appearance is rich in shape, and the foam cement is stable. The application has the advantages of low consumption and low cost. It can be widely used in ground heating decoration projects and roof landscape decoration projects, which can reduce operations on a large scale.
2. Polymer cement foaming agent
The product is a shallow viscous liquid with low content, strong diffusibility, uniform quality, stable quality, adsorption and foam. Because the foam surface formed by the adsorbent has high strength and stability, the foam cement made of the adsorbent has an independent closed state, and the bubbles are not produced with the bubbling, but the foam is produced. Good permeability resistance of cement products. Its powerful foam cement can reach more than 1.5 meters without collapsing.
