Abstract: The paper discusses theoretical and experimental investigation of alkaline activated non-autoclaved foam concrete. It was decided to a use slag binder as a part of non-autoclaved foam concrete. The effect of the silicate module on the rheological and mechanical properties of the slag binder is investigated. It has been established that a decrease in the activator module from 3 to 1 increases the initial and final setting time of the slag alkaline binder 3 times. When the activator module decreases from 3 to 2 compressive strength increases from 27 to 49 MPa, and when it decreases to 1 the strength index changes slightly.

Keywords: alkali-activatedn on-autoclaved foam concrete, ground blast furnace slag, fly ash, setting time, compressive strength.

Pages: 42-45.
