Abstract

This work focuses on the adjustment of formulations to determine the influence of the main component quantities on render properties. The purpose of the research is to create external silicate renders with high properties by changing the quantities of the main components of renders. The limits of the quantitative relations between the render components based within which the technical parameters of prepared renders and quality indicators of their coatings, were determined. The optimal binder and filler quantitative mass ratio was found. The exemplary composition of silicate render compliant with the said ratio is presented. It is a cost-efficient and general-purpose external render with good technological and technical characteristics.The tests performed correspond with the trends of development of the global industry of finish materials, i.e. the decrease in the quantity of organic components and the increase in the quantity of non-organic substances.
