At the present time the development of new generation building composites, distinguished not only by high performance characteristics, but also contributing to the optimization of the system “human-material-living environment” is actual. In construction, sand-lime bricks are widely used as wall material. According to the normative documentation in its production pure quartz sand with a minimum content of clay impurities are used. However, there is a large proportion of quartz sands containing clay impurities. Such rocks do not satisfy the requirements of normative documents to sands for silicate materials. The urgent task is to conduct researches on development of building composites of new generation with the use of this type of raw materials. As a result of this research it is shown that fine sands characterized by the presence of clay impurities, represented by miscible clay minerals can be used as raw materials for the production of silicate materials. The use of such raw materials can optimize the microstructure and accelerate the synthesis of new formations represented by low-base calcium hydrosilicates. Increase of strength characteristics of products is caused by formation of new formations of increased degree of crystallinity, and also at the expense of optimization of granulometric composition. The content of the required percentage of used raw materials in the raw mix of sand-lime bricks contributes to an increase in strength characteristics of raw bricks by 2 times, the finished product by 1.8 times, which simplifies the production of products of complex shape.
