Descripción del producto

Best price strong CSA expansive agent

Product description:CSA expansive agent is similar to DENKA CSA *0# in some ways.Its raw material is calcium sulphoaluminate.With favorable price and high efficient expansive ratio,CSA expansive agent is becoming more and more popular in field of construction to improve the quality and shorten erection time.

Areas of applications: CSA expansive agent, expansive additives for concrete,expansive cement, expansive mortar for deomolition, strong bond ceramic tile adhesive,crack resistance water proof agent,non shrinkage grouting,anti-crack self-leveling materials.

Features:
1.Low alkalinity.High-efficiency CSA Expansive Agent has a very low alkali content (R2O<0.3%) which is beneficial to avoid AAR in concrete.
2.Short stable stage of expansion. The stable stage of expansion is not more than *4 days, thus the ultimate strength of concrete is not affected.
3.Low dosage and high expansion capacity. The normal dosage of High-efficiency CSA Expansive Agent is 6~8% by the weight of ordinary cement, which is lower compared with other expansive additives such as UEA and CEA (their dosages are about *0~*2% by the weight of cement) in the market.
4. Prevents cracking due to drying shrinkage and hydration heats.
5.Increases the water tightness of concrete and thus is useful for waterproofing buildings.
6.Enables the manufacture of high strength concrete products through chemical prestressing.

The effect of High-efficiency CSA Expansive Agent dosage on strength of cement mortar:

Longitudinal change of mortar:

Application method:
1. Dosage
High-efficiency CSA Expansive Agent is used as a part of cement, its proportion to ordinary Portland cement depends upon the intended use and the degree of restraint. The proportion of High-efficiency CSA Expansive Agent to ordinary cement generally used in China is about 6~8%.

2. Mixing
High-efficiency CSA Expansive Agent and ordinary cement must be thoroughly and uniformly mixed in a mechanical mixer with aggregate and water for a slightly longer time than normal concrete.

3. Curing
To ensure the proper development of the ettringite needle crystals which are important in preventing shrinkage cracks which occur during drying period, it is recommended that water be sprayed or membrane curing onto the concrete surface for curing at least *4 days after the concrete is cast.

4. Storage
High-efficiency CSA Expansive Agent is more sensitive to water and moisture than other cementitious material and is therefore packed in completely waterproof bags and should always be kept and stored in a dry place.
