Miryuk O.A. Porous cement-free compositions

Abstract

This article is devoted to the formation of porous compositions based on alkali solutions. The effect of an alkali solution composition on foam mass was studied. The augmented stability of foam from Na2O(SiO2)n solutions was revealed. The dependence of foam mass properties on the addition of NaOH into Na2O(SiO2)n so-lution was shown. It was revealed that synthetic foaming agents were preferable to form a porous structure of alkali-silicate compositions. It was shown that additional formation of porous foam mass was possible due to the addition of gas-forming agents and hollow granules. The revealed features of the formation of porous compositions served as a basis for a cement-free foam concrete manufacturing process.

Keywords
