ADJUVANT FOR INCREASING THE SHORT-TERM MECHANICAL STRENGTH OF A HYDRAULIC COMPOSITION WITH A REDUCED CLINKER CONTENT

This relates to the use, for improving the mechanical strength of a hydraulic composition based on a cement composition including: from 20 to 64% by weight of clinker; from 5 to 60% by weight of activated clay; from 0 to 35% by weight of limestone; and from 0 to 10% by weight of calcium sulfate, the...

Summary:This relates to the use, for improving the mechanical strength of a hydraulic composition based on a cement composition including: from 20 to 64% by weight of clinker; from 5 to 60% by weight of activated clay; from 0 to 35% by weight of limestone; and from 0 to 10% by weight of calcium sulfate, the proportions being relative to the dry weight of the cement composition, of from 0.2 to 5.0% by weight relative to the dry weight of cement composition, preferably from 0.2 to 1.0% by weight relative to the dry weight of cement composition, of at least one adjuvant including at least one alkali metal salt chosen from alkali metal formate, carbonate, chloride, hydroxide, oxalate, thiocyanate, silicate, sulfate or nitrate salts, or a mixture thereof.
