Abstract
In this article the possibility of using construction waste (including waste of dismantling of buildings) when receiving building ceramics, heat-resistant materials based on liquid glass and materials based on natural hardening cement binder is considered. The purpose of study was development of building materials compositions made with using of secondary crushed stone screening HYPERLINK "https://www.multitran.ru/c/m.exe?t=2400068_1_2&s1=%EE%F2%F1%E5%E2" of dismantling of buildings for various purposes, which would suit all state standards. Also these materials would have some improved physical-mechanical characteristics and would be more eco-friendly. Optimum compositions of materials made with use of building mineral waste and physical-mechanical characteristics of received materials are given. For research of waste structure and synthesizable materials structure X-ray phase, differential-thermal methods of analysis and grain size measurements were used. The geological-ecological evaluation of secondary crushed stone screening use efficiency in developed technologies is given.
