ENVIRONMENTAL ASPECTS OF THE USE OF BATTLE GLASS FOR THE PRODUCTION OF GLASS CONCRETE

Abstract

The technology of glass concrete based on dispersed container and sheet glass has been developed. It is shown that when Portland cement and cullet are ground together, when a specific surface area of 5890 – 6450 cm2/g and a particle size of 3.4 – 3.6 microns with a dispersed glass content in the composite of 20 – 50 wt. % with hyperplasticizer glass concrete corresponds to class B30 – B40, which meets the requirements of regulatory documents. The microstructure of glass concrete and the features of its dehydration when heated to 1000 °C investigated. Using X-ray phase analysis, it was found that sodium-calcium hydroaluminosilicates such as gmelenite and thomsonite are formed in glass concrete.
