More Information
Summary:The present invention relates to the use, for improving the mechanical strength of a hydraulic composition based on a cement composition comprising: - 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, - 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 comprising 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.
