Method for increasing the making ability of binding composites containing portland cement, fired clay, and limestone, additives used in this method, and the hardening composite obtained by this method

Abstract

The invention relates to a method for increasing the workability of a binding composition containing calcined clay, lime, and Portland cement. This method includes the addition of an additive containing at least one PCE and at least one additive chosen from a group including sugar acids, sugars, sugar alcohols, and hydroxycarboxylic acids. The invention relates to the additive used in the above-mentioned method and the hardening compositions, especially concrete and mortar, that can be obtained by this method.
