Curing Cements, Concrete, And Artificial Stone

Abstract
This additive is used in the production of normal and special construction solutions, concrete and pieces. It enhances the puzzolana activity and the strength properties of the construction solutions and concrete, by using familiar technologies for preservation, transportation and dosage of the cement. Its relatively high volume thickness reduces transportation costs. The additive contains (in %) : micro silicon dust (17 to 50), dust from Thermal Power Stations (47 - 80), and a chemical additive of 0.01 to 3 of dry substance from the mass of the active mineral additive. The chemical additive is based on a soluble melamine resin, lignosulphonates and formaldehydes.
