Influence of Nanosized Silica Component on Physical and Mechanical Properties of a Composite Gypsum Binder

Abstract

The work presents the results of development of the composite gypsum binder (GB) with nanostructured binder on the basis of silica component (NBC). Introduction of NBC changes the kinetics of hardening, as well as improves physical and mechanical properties of gypsum system. Analysis of the microstructure of the GB has demonstrated in the presence of the NB the size and morphology of crystals are changed, promoting the formation of fine-crystalline structure and increase the contact area between new formations, compared to NBC – free gypsum system. Experimental studies have shown that the mechanical properties of the composite gypsum application of NBC increased, reduced water absorption, density increases, and increases the setting time.

The Effect of Polyvinyl Alcohol on the System of Cement-Free Binding Alumino-Silicate Composition

“…The studies were carried out in the field of application of nano-structured binders as a modifying additive and active binder component in the preparation of autoclaved hardening materials [10][11][12], composite binders based on cement [13][14][15], composite gypsum binders [16,17] and non-autoclaved hardening cellular materials [18,19].…”

Estimation of the Efficiency of Mechanical Activation of Silica-Containing Rocks

“…Полученные энергетические характеристики механоактивированного кремнеземсодержащего сырья позволили сделать вывод о возможности использования диспергированных горных пород в качестве компонентов строительных материалов [11][12][13][14].…”
