What are the admixtures for cellular concrete?

Cellular concrete is a kind of concrete that is made by mechanical foaming. Common admixtures for cellular concrete include foaming agents, water reducers, thickeners and pump stabilizers.

Cellular concrete is a kind of concrete that is made by mechanical foaming. First, the foaming agent is made into foam, and then the foam is added to cement, magnesia, and gypsum slurry to form a foam slurry, and then cured by natural steam curing. Cellular concrete is a member of the concrete family. In recent years, great attention has been paid to the research and development of Cellular concrete, making its application in the construction field more and more extensive. It has the characteristics of light weight, good thermal insulation performance, good sound insulation, and fire resistance, good overall performance, good low elasticity and shock absorption, strong waterproof performance, good durability, convenient production and processing, environmental protection, and convenient construction.

For the normal admixture, we provide, 

‌Foaming agent‌: Foaming agent is one of the essential admixtures in aerated concrete. It can expand the water in concrete to form bubbles, thereby making the concrete lighter and improving its thermal insulation and seismic resistance. Commonly used foaming agents include organic foaming agents and inorganic foaming agents. Organic foaming agents have good foaming properties but are more expensive, while inorganic foaming agents are cheaper but have relatively poor foaming properties.

‌Water reducer‌: Water reducer can reduce the amount of cement in concrete and reduce the water-cement ratio, thereby improving the strength and durability of concrete. The function of the water reducer is to reduce water wave fluctuations and improve the plasticity and workability of concrete. Commonly used water reducers include shrinkage agents, cohesive water reducers, and water-reducing protective agents.

‌Thickener‌: Thickener can improve the fluidity and consistency of aerated concrete, and increase its processability and workability. Thickeners can be divided into high-strength and low-strength types according to the scope of use. High-strength type is suitable for high-strength concrete, and the low-strength type is suitable for ordinary concrete.

Pump stabilizer: Pump stabilizer is used to prevent the separation of slurry and anti-dispersion during concrete pumping. It can stabilize the flow performance of concrete and improve the uniformity of concrete, thereby improving pumping efficiency and reducing construction costs.

The use of these admixtures can significantly improve the quality and performance of aerated concrete, but the specific selection should be determined according to the construction project and the properties of the concrete.
