FIELD: construction.
SUBSTANCE: concrete mixture contains a high-lime flue ash of thermal power plants - TPP, microsilica, water and mineralized drains - waste of non-ferrous metallurgy production, containing from 80 to 350 g/l of calcium and sodium chlorides, additionally contains TPP slag with fraction of 0.16-5 mm as a filler at the following ratio of components, wt %: high-lime flue ash of TPP 42-45, TPP slag of specified fraction 35-40, microsilica 3-4, mineralised drains with specified content of chlorides 1.5-2.5, water - balance.
EFFECT: reduced density and higher strength of concrete and improved ecological environment in the region.
