Adjuvant, useful for hydraulic binder for the manufacture of elements for the construction field, comprises e.g. alkyl sulfonate, alphaolefinsulfate and/or alkylbenzenesulfate; and calcium salt soluble in water

摘要

Adjuvant (I) comprises: an alkyl sulfonate, an alkylethersulfonate, a hydroxyalkylethersulfonate, an alphaolefinsulfonate, an alkyl benzene sulfonate, an alkyl sulfate, an alkyl ethersulfate, a hydroxyalkylethersulfate, an alphaolefinsulfate and/or alkylbenzenesulfate; and a calcium salt soluble in water. Independent claims are included for: (1) hydraulic binder comprising the adjuvant; (2) hydraulic composition comprising the hydraulic binder; (3) lightweight concrete comprising the composition; (4) manufacturing a hydraulic composition comprises contacting the adjuvant, water and the hydraulic binder; (5) manufacturing a lightweight concrete comprising introducing gas into the hydraulic composition; and (6) element for construction field, made of the hydraulic binder, hydraulic composition or lightweight concrete.
