Building Ecomaterials Based on Secondary Raw Material

Abstract:

Mineral raw natural resources are not unlimited. Preservation of such non-renewable resources is the most urgent task of mankind. The development of non-waste technologies, the integrated use of secondary raw materials, which simultaneously reduces environmental damage - one of the ways to solve environmental problems. Utilization of wastes makes it possible to solve issues of environmental protection as well as resource saving. In the light of environmental requirements, building materials based on recycled materials, including cellulose-containing solid waste, have significant advantages over other traditional materials. Development of technology for obtaining new effective environmentally safe composite highly filled materials based on cellulose-containing solid household waste for the production of construction products is a rational link in solving the general problem of improving the environmental situation. In the article there are three main ways of combining gypsum binder with cellulose-containing solid household waste. Investigations were carried out on the effect of changing the ratio of cardboard / gypsum binder, specific pressing pressure, sequence of combination of components on the properties of the final product. The strength of the material was determined from the values of the flexural strength, the compression to complete destruction of the sample, and at 10% deformation. Studies have been carried out to increase moisture resistance. The results showed that the most optimal way of combining is the 2 way. The increase in moisture resistance is significantly enhanced by the action of organosilicon hydrophobisers.
