CSA Binder is a hydraulic binder based on calcium sulfo-aluminate, rather than calcium aluminates which are the basis of Calcium Aluminates Cement or calcium silicates which are the basis of Portland Cement. The difference gives CSA Binder properties particularly suites to formulators of products such as self-leveling or self-smoothing compounds, rapid screeds, tile adhesives, non-shrink grouts, rapid setting and special mortars.
CSA Binder is used in formulated products either as a hydraulic binder by itself or with the addition of calcium sulphates or in combination with Portland cement. The setting time is quicker than that of Portland cement, and it also has a rapid strength development. CSA Binder does not release free lime during hydration thus eliminates the major cause of efflorescence.
