Production Technology of Waterproof Porous Aggregates Based on Alkali Silicate and Non-bloating Clay for Concrete of General Usage

The paper presents an investigation into the composition and production technology of porous aggregates for concrete of general usage. As the main components of the composition the authors suggest using of alkali silicate and non-bloating clay. The results of the investigating different compositions and technologies are analyzed. The compositions and technologies finally introduced in the paper make it possible to use not only non-standard materials but also to diminish fuel and power resources by way of reducing the baking temperature.
