Concrete Expansion

1, Appearance: white powder suit for GB23439-2009 concrete expansion standards.

2, the content is 6.0% -12.0%, the recommended dosage is generally 8 to 10%.

3, concrete mixed with this agent sulfate resistance than ordinary concrete, for water pollution hazards. Good crack resistance,Concrete water loss or modest decline in the generation of shrinkage or shrinkage produced by the hydration heat loss temperature is lowered to close reduced to its ultimate tensile concrete will crack. Expansion of the joint action component, to achieve effective anti-cracking effect.

4, concrete impermeability grade ≥S30, antifreeze label ≥D150, concrete mixed with this agent stable performance, steady increase in expansion properties of concrete,Late strength continued to grow, thereby increasing the durability of concrete, compactness, extending the service life of concrete.

  ST-01D-type concrete expansion agent 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.

1, Packing: 50 kg plastic woven sack bag, net weight 50kg, it can also be customized according to customer requirements.

2, Storage: This product should be stored on wooden pallets, storage keep dry dedicated warehouse or fixed place, Moisture is strictly prohibited .product shelf life of six months, expired product should be re concrete physical performance test, only data after passing allow to use.
