Additive composition for concrete and Mortar, shrinkage compensated

摘要

Composition of Calcium sulphoaluminate hemihydrated gypsum, calcium sulfate and calcium oxide. In contact with the Water of Concrete or Mortar produces ettringite obtained the following characterization Chemical Al2O3: C 32h2o CaSO4.This composition also ensures the controlled expansion in time; even when they are in permanent contact with water, The reaction products are produced remain stable. In the manufacture of these components are mixed Dry batch Production without using any temperature to cool or heat the same for homogenization.
