Expansive Agents for Concrete

 ST-01D-type expansive agent for concrete is a chemical admixtures added in cement when the cement setting and hardening, along with volume expansion, contraction and tension compensates produce prestressed reinforced concrete to fill the gap and the full effect. This product is incorporated in concrete, can generate reactive cement combined with water and the expansion crystalline hydrates --- ettringite (C3A.3CASO4.32H2O), the concrete in the early and mid produce moderate expansion, constraints in steel and ortho next, it should be expanded into pressure, this pressure can be substantially offset by the tensile stress generated when the concrete shrinkage, thereby preventing or reducing shrinkage and cracking of concrete, and concrete densification, which can also improve the anti-cracking concrete infiltration capability to meet the structural waterproof effect. Thus becoming one of the preparation of structural waterproof and ideal material for high performance concrete.
