Product Description

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.
