C.S.A Expansive Agent for Building Products

详情

Outline 　　 C.S.A-I Expansive agent for building product contains mineral compositions 4CaO·3Al2O3·SO3，CaO·Al2O3, CaO·***** will react in the presence of lime and calcium sulphate to hydrate entringite. Applications 　　 1、Rapid repair mortars 　　 2、Fast setting tile adhesives 　　 3、Self-leveling mortars 　　 4、Self-smoothing mortars 　　 5、Non-shrinking grouts 　　 6、Glass fibre reinforced concrete(*****) C.S.A-II 　　C.S.A-II Expansive agent contains mineral elements of C4A3S & F·CaO.According to the test by China Building Materials Academy, **8% addition of CSA(based on cement weight)will produce beforehand stress approx.0.**0.7MPa so that it can offset the shrinking stress occured when the concrete is hardening and obtain the result of compensating shrink and preventing cracks. Applications 　　 1、Expansive agent for concrete 　　 2、Non-shrinking grouts 　　 3、Anchor bolt grouts 　　 4、Rapid hardening mortars 　　 5、Self-leveling mortars
