Ecologically safe composite building materials based on cellulose-containing solid household waste

Abstract

In the article, three technological methods for obtaining a high-filled construction composite on the basis of gypsum binders and cellulose-containing solid household waste are considered. The results of a study on the effect of changing the ratio of cardboard/gypsum binder, the specific pressing pressure, the sequence of combining the components on the properties of the final product are presented and presented. The strength of the material was determined from the final values of the flexural and compressive strengths until the specimen completely destroyed and at its 10% deformation. Studies have been carried out on the possibility of giving the building composite water resistance. The results of the research showed that the most optimal way of combining is the 2 way. The increase in water resistance of the resulting composites is significantly increased when using silicone hydrophobisers.
