How to correctly select concrete admixtures during construction?

Concrete admixtures are an indispensable chemical substance in concrete construction. They can significantly improve the performance of concrete, improve its fluidity, water retention, erosion resistance, etc. There are many types of admixtures. According to their functions, they can be roughly divided into water-reducing agents, air-entraining agents, pumping agents, retardants, early strength agents, waterproofing agents, rust inhibitors, antifreeze agents, expansion agents and colorants.

Water reducing agent is the most commonly used concrete admixture. It can reduce the water consumption of concrete, improve the workability of concrete, and make it easier to pour and vibrate. When adding less water, the strength and stability of concrete can still be maintained, which is very conducive to reducing the water-cement ratio and improving the strength and durability of concrete.

Air-entraining agents can introduce a large number of bubbles and increase the number of pores in concrete, thereby improving the lightweight and thermal insulation properties of concrete. In winter construction, air-entraining agents can also improve the frost resistance of concrete and prevent it from freezing damage.

Pumping agents can improve the flowability of concrete, making it easier to pump to high places, thereby reducing construction costs. In the construction of high-rise buildings, the role of pumping agents is very obvious, which can improve construction efficiency and shorten the construction period.

Retarders can extend the initial setting time of concrete, allowing more time for pouring and vibrating, improving construction efficiency. In high-temperature seasons or when long-term transportation is required, the role of retarder is more obvious.

Early strength additives can accelerate the hardening process of concrete, allowing it to reach sufficient strength in a shorter period, thereby shortening the maintenance cycle. In winter construction, the role of early-strength additives is more significant and can improve the frost resistance of concrete.

Waterproofing agents can improve the waterproofing properties of concrete and prevent it from being eroded by groundwater. In places such as basements and pools that need to be waterproofed, waterproofing agents play a very important role.

Rust inhibitors can prevent steel bars in concrete from rusting and extend the service life of buildings. In places such as offshore structures and bridges where steel bars need to be prevented from rusting, the role of rust inhibitors is very critical.

Antifreeze prevents concrete from freezing in cold weather, preventing structural damage. In winter construction, antifreeze plays a very important role in improving the frost resistance of concrete.

Expanding agents can cause concrete to expand during curing, improving its strength and durability. In reinforcement projects, expansion agents play a very obvious role and can improve the seismic resistance and durability of the structure.

Staining agents add color to concrete, giving it a beautiful appearance. In decoration projects, colorants play a very important role and can produce decorative concrete in various colors.
