Combined utilization of polymer and brick waste for the production of facing composite material
Incoming article date: 30.04.2023The paper presents the results of research on the development of the composition of the raw mixture for the production of facing composite material for construction purposes. The composition of the raw material mixture included a brick fight as a filler, waste products from non-plasticized polyvinyl chloride as a binder and methylene chloride for dissolving polymer waste. This composition allows mixing and pressing without heating, which eliminates the possibility of destruction of the polymer component. After pressing, heat treatment is carried out at the solvent evaporation temperature. The paper shows the dependences of the main physical and mechanical characteristics of the resulting material on the degree of filling. The maximum amount of filler has been set, which allows to obtain the material without a lack of binder. With a lack of binder, a decrease in strength and an excess of the proportion of open pores over closed ones were observed. According to the results of the experiments, the polymer : solvent ratio and the degree of filling were selected, allowing to obtain a material with the maximum value of strength characteristics. Practical application of the developed composition of the raw mixture will allow complex utilization of low-demand and large-tonnage polymer and brick waste to obtain composite material for cladding buildings and structures.
