The influence of three types of surfactants on the following clinker properties: specific surface area, sorption behavior (hygroscopicity), water repellency, and flowability has been studied. Experimental results show that the surfactants have different influence on the grinding kinetics and properties of clinkers that mainly depend on the surfactants concentration than their origin or state of matter. Use of special surfactants as grinding aids is proposed. Molecules of these compounds should consist of a functional group and hydrocarbon chain that does not contain additional functional groups. Such surfactants provide not only grinding accelerating but also storage life prolonging. The research work demonstrates that fatty acids and organosulfur compounds satisfy these conditions and they can be successfully used as a cement grinding aid.

An approach to water emulsions modification with structure forming additives, namely cellulose esters, is proposed in the article. Influence of the film former origin on the system rheological properties at different shear-strain rates was examined. Structural and mechanical, as well as rheological properties of the studied systems were determined. The results confirm that hydroxyethylcellulose has a greater structure forming effect in comparison with carboxymethylcellulose. Hydroxyethylcellulose provides well-definite pseudoplastic properties to the two-component systems that facilitate the production and application of paints. The results of the investigation could be used in the emulsion paint (coatings) production.

The results of comprehensive researches of the physico-chemical properties of kaolins as extenders of water-dispersion paints are shown in the article. The results of RF-analysis, energy state estimation of researched kaolins surface with different content of nonclay components and index ordering of the crystal structure are analyzed. Quantitative IR-analysis of basic functional groups of kaolins surface has been conducted to estimate their reactivity.Kaolin is a mineral rock that is fully or partially composed of kaolinite. Minerals of kaolinite are characterized by such theoretical chemical composition (%): SiO 2 -46.5; Al 2 O 3 -39.6; Н 2 О + -13.9, which is expressed by the formula Al 2 O 3 ⋅2SiO 2 ⋅2Н 2 О with the theoretical ratio of 1: 2: 2 [12].Kaolins are widely used in industry in the manufacture of various products. Kaolins are used as extenders in the manufacture of paints, plastics, rubber, and other products. The composition of the basic chemical elements, the presence and activity of functional groups of kaolins when used in water-dispersion paints are equally important. These properties allow predict their adsorption ability and interaction with polymers in aqueous dispersions to obtain optimal composition.
