Csa Expansive Agent

Shrinkage Reducing Admixture (Shrinkage Compensate Agent) is obtained by blending suitable natural anhydrite with a specially manufactured clinker which consists essentially of calcium sulpho aluminate and CaO. Our CSA Shrinkage Reducing Admixture (Shrinkage Compensate Agent) are used in a wide range of applications, such as for reducing and compensating the hydraulic shrinkage of cementitious construction products, structural self-waterproofing construction, anti cracking and moisture proof of reinforced concrete structures, late poured bands, non-shrinkage grout, chemical pre-stressed concrete products, etc. In addition, a hydration heat control type of expansion material is also available, to which a hydration-controlling agent has been added to prevent thermal cracks. Compared with UEA and CEA, our CSA Shrinkage Reducing Admixture (Shrinkage Compensate Agent) have the advantage of low alkalinity, short stable stage of expansion, low dosage and high expansion. Our CSA Shrinkage Reducing Admixture is similar to Denka CSA.
