The Effect of Polyvinyl Alcohol on the System of Cement
Cement-free binding materials are a promising type of materials. The relevance and the possibility of increased efficiency of these materials are reasoned by environmental and technical-economic conditions of the current state of building industry. As a result of research the following effect was established polyvinyl alcohol on cement-free highly concentrated aluminosilicate binder
