A liquid additive composition comprising a particulate material, an organic carrier fluid, a viscosifier, and an alcohol alkoxylate surfactant; wherein the particulate material is substantially insoluble in the organic carrier fluid; wherein the particulate material comprises a water-interactive material and/or a water-insoluble material; wherein the organic carrier fluid comprises a glycol and/or a glycol ether; and wherein the viscosifier comprises amorphous silica. A method comprising (a) contacting a particulate material, an organic carrier fluid, a viscosifier, and an alcohol alkoxylate surfactant to form a mixture; and (b) agitating the mixture to form the liquid additive composition.

A foaming agent, more particularly for the foaming of a building material/binder paste for producing pory lightweight-construction and insulating materials, is improved in terms of its stability and usefulness at relatively low outdoor temperatures. The foaming agent in the form of an aqueous-organic solution comprises or consists to an extent of at least 85 wt % of the following constituents: a) a surfactant component which comprises at least one foam-forming ionic surfactant, b) a fatty alcohol component which comprises at least one fatty alcohol and at least one ethoxylated fatty alcohol in a FA/FAEO mixing ratio of 95:5 to 0:100, c) a glycol component which comprises at least one constituent of the group of alkyl glycols, alkylene glycols up to C6 alkyl, diglycols, especially alkyl diglycols and diglycol ethers, and water.

The present invention provides methods, admixture compositions for treating clay-bearing aggregates used for construction purposes, and aggregate compositions for construction purposes. The clay-bearing aggregates are treated with a cationic copolymer made from two and preferably three different monomer components. Cementitious compositions containing the treated aggregates are also described.

A fluidizing composition in the form of a liquid or in the form of a powder including at least one superplasticizer chosen from polycarboxylate ethers, characterized in that it includes from 1 to 20 parts by weight of at least one aromatic hydrocarbon sulfonic acid or one of its salts chosen from alkali salts, alkaline-earth salts or one of their mixtures, for 100 parts by weight of the superplasticizer. A method for preparing such fluidizing composition, a dry mortar incorporating the fluidizing composition, as well as plasters prepared from the dry mortar are also described.
