Study of hydration products of non-autoclaved foam concrete

Abstract

The published work presents an X-ray phase analysis of non-autoclaved foam concrete. According to the results of X-ray phase analysis of non-autoclaved foam concrete, it was found that by 56 days of normal hardening, further reactions of cement hydration and binding of $Ca(OH)_2$ occur, reflections of tobermorite-like low-basic calcium hydrosilicates CSH (II) increase with d = (3.07; 2.10 ) Å, which are involved in the hardening process, which consists in the monolithic foam concrete matrix, the formation of a glossy porous layer, the healing of defects in the interpore partitions, which leads to a significant increase in the operational characteristics of the material.
