Abstract

The influence of three types of technogenical products (cement dust – waste of cement production, autoclaved cellular
concrete waste and condensate from the autoclaves) on silicate concrete properties was analysed in this paper. Use of
these products is limited and the condensate is practically unused for production. It was determined that the mixture of
water and condensate (1 : 1) could be used to slake the silicate mixture, then the compressive strength of the silicate
concrete increases by 15%, and additionally including 3 wt.% of cement dust or 5 wt.% of porous concrete waste, the
silicate concrete compressive strength increases from 21 % to 26 %.
