What Is Plasticizer in Concrete?

Generally, the higher the water content of concrete, the better its fluidity and workability. But when concrete has enough moisture, the strength of concrete after solidification is inversely proportional to the moisture content. Therefore, if the concrete is to have high strength, the water content of the concrete should not be too much, and the T addition property will be worse at this time. The plasticizer can reduce its water content without affecting the workability of the concrete. Agent), but also improve the strength of concrete. If pozzolan is added to concrete, plasticizer will also be added to increase strength. This method is often used to increase the strength when producing high-strength concrete or fiber reinforced concrete.

Performance characteristics of plasticizer:

(1) Excellent compatibility with resin;

(2) High plasticizing efficiency;

(3) Stable to heat and light;

(4) Low volatility;

(5) Low migration;

(6) Resistance to extraction of water, oil and organic solvents;

(7) Good flame retardancy;

(8) Good electrical insulation;

(9) Colorless, tasteless and non-toxic.

It has good fluidity and pumpability, improves the workability of concrete, does not segregate, and does not pour water.

The use and development of concrete have attracted much attention. Concrete synergist has a high-efficiency stimulating function: to stimulate water reducing agent and dispersing cementitious materials to a greater extent.

Penetration and solidification: Effective penetration of 5~15mm, chemical reaction with the substances in the concrete, forming a compact whole; effectively improving the hardness, density, and compressive strength of the concrete, and increasing the rebound by 40%~60%.
