Abstract
The influence of impregnation by surface gidrofobizatsii the water resistance of gypsum composites
Incoming article date: 02.04.2017Abstract: Among the variety of modern mineral binders occupy a special place gypsum binder, which has many positive properties: efficiency of production in comparison with cement, quick hardening, architectural expressiveness of features with the use of pigments, abundance of raw materials and high technology. However, its application is limited by low resistance of the material. The paper presents a brief analysis of the main methods of improving the water resistance developed at the moment in construction: increasing the density of products, improvement of water resistance by impregnating the surface of various materials, the use of various chemical additives, a decrease in the solubility in water of calcium sulphate, the use of combined methods of improving the water resistance, the creation of composite
