Application of IR spectroscopy for studying structure formation in low-cement concretes

Abstract

Composition optimization and the areas of application of uncalcined refractory concretes dictate the need to study the structure-formation processes occurring in these concretes as temperature increases to the operational level. Methods for using IR spectroscopy to study structure-formation processes in refractory aluminosilicate concretes are examined.

“…Generalizing the results described in [6,7] and obtained in the present investigation, it can be stated that as a result of heat treatment of the fireclay cement samples at 110°C a structure characteristic of concrete is observed -an amorphous gel-like phase is detected. The binder of the material is based on an aluminosilicate phase and an alumina phase, an almost isotropic substance; in addition, calcium hydroaluminates are determined in the interior volume of the particles.…”
