Selection of the Optimal Composition of Lightweight Concrete on Porous Filler from Quartz Porphyer
Abstract: The article presents the results of research work on the development of filling mixtures, porous aggregates; heat-insulating and structural-heat-insulating concretes using industrial waste. The optimal compositions, manufacturing technology and basic physical and mechanical characteristics of the developed building materials and concretes have been determined. It should be noted that the building materials industry is a construction industry for which the issues of resource conservation and the use of industrial waste are especially relevant. Today the construction industry uses hundreds of millions of tons of various mineral raw materials, and the share of raw materials costs in the cost of production is 25…50 %. Under these conditions, the attraction of millions of tons of industrial waste as a raw material can and does bring a significant national economic economic effect. Currently, large-scale industrial waste, which is of interest as a raw material for the production of building materials and concrete, is generated at the enterprises of dozens of organizations, companies and departments. At the same time, enterprises producing construction materials and products use no more than 10…12 % of all generated waste. In this regard, one of the most important problems at the moment is the maximum and comprehensive use of waste from various industries as raw materials for the production of efficient and cheaper building materials.
