Calumex E.A.

Calumex® E.A. is a factory-controlled pre-blend of basic Calumex® C.S.A. cement and synthetic anhydrite. It is used as an additive to Portland cement to achieve either shrinkage compensation or positive expansion, depending on the applied dosage.

The temperature development during hydration caused by the addition of Calumex® E.A. will contribute to strength development in the final mortar. Furthermore, due to the controlled ettringite formation achieved by the combination of Calumex® E.A. with Portland cement, early strengths will be significantly improved, increasing efficiency in many applications.

The recommended dosage of Calumex® E.A. is an 8-12% replacement of Portland cement content. Be mindful that an excessive dosing of Calumex® E.A. will lead to positive expansion, which could lead to cracking and would be undesirable for many applications.
