Research of the environmentally safe waste-based building materials
Introduction: in the article the estimation of new ecological safety biopositive polymer-mineral composite (BPMC) building materials obtained with the use of technogenic wastes is considered. This approach is one of the ways to solve the problem of improving the environmental safety of the environment. Materials and methods: BMPC environmental safety studies were performed using microstructural, X-ray and elemental analysis methods, studying physical and mechanical properties and fire safety. Man-caused wastes inventory and classificational ecological assessment by the lif e cycle was carried out. Results: the conformity of the Baikal region man-caused wastes (such as fly ash from heat-power engineering, aluminosilicate microspheres, isolated from bottom ash wastes, marble dust (microcalcite), industrial waste of polyvinylchloride (PVC), as well as small-sized mica waste in the form of vermiculite) to the basic characteristics that allow to use this wastes in the production of BMPC-products by extrusion as fillers. The man-caused wastes ecological utilization mechanism was developed. Composition of composite materials, in which industrial PVC waste is used as the matrix, and fly ash, ash microspheres, marble dust and vermiculite as fillers, were developed. The proposed technology for the production of BPMC products allows the use of technogenic wastes in a wide range in the composition from 20 to 60 %. The new biopozitive polymer-mineral composite products properties were studied. Conclusions: the conducted studies of the composition and properties of samples obtained using different types of man-made waste in the polymer-mineral composites production proved that the production of BPMC products ensures the building materials and environmental safety through the reliable and durable materials production that comply with regulatory requirements. According to the life cycle environmental safety assessment, the waste products obtained on the basis of waste have significant advantages in terms of a technical and environmental characteristics set.
