Effective building ceramics for transport infrastructure

Abstract

In this article the possibility of using porous silicate-containing waste when receiving an effective ceramic brick (which is used for erection of a transport infrastructure buildings and constructions at low temperature) is considered. The purpose of study was development of ceramic brick compositions made with using of granulated blast-furnace slag and with using of a ground foam concrete crush, which has a lower thermal conductivity coefficient of a crock, and meets the requirements of state standards for other indicators. Optimum compositions of materials and physical-mechanical characteristics of received materials are given. To study the composition of technogenic raw materials and the structure of synthesized ceramic materials the following methods were used: X-ray phase and differential-thermal methods, IR- Fourier-transform spectroscopy, electron microscopy, mercury porometriya method. The estimation of ecological and economic efficiency of use of porous silicate-containing waste is given. This estimation shows a significant reduction of anthropogenic load on the environment, и reduction of the cost of production of ceramic bricks with improved heat technical characteristics, what is needed for erection of buildings and constructions in cold regions.
