Csa binder is a hydraulic binder based on sulfo-aluminate cement, rather than calcium aluminates which are the basis of calcium aluminate cement (fondu cement) or calcium silicates which are the basis of portland cement. Csa binder is used in formulated products either as a hydraulic binder by itself or with the addition of calcium sulphates or in combination of portland cement. When used as an additive, the following properties can be developed, such as: fast setting time, rapid hardening, the early strength and final strength gains, lower alkalinity (ph value), good expansion value, cracking resistance, corrosion resistance, it can also worked in low temperature. Csa binder can be applied to a wide range of products: Fast setting cement and mortars Rapid repair mortars Fast set tile adhesives Self levelling compounds Self smoothing mortars Non-shrinkage grouts Water stopping mortars Glass fiber reinforced concrete (grc), etc.
