Influence of Type of Crimean Quarries Carbonate Waste on Durability, Сuring Time and Structure Formation of Slag-Lime Concrete on the Basis of Soluble Glass With Silicate Module 1,5-1,7

Abstract

In the article the infl uence of carbonate waste on durability, curing time and structure formation of slag-lime concrete of diff erent compositions with diff erent curing conditions on the basis of soluble glass with silicate module Mc=1,5-1,7 is considered as well as Crimean quarries stone-cutt ing waste. Slag-lime binders are diffi cult in-use because of curing time and its infl uence on concrete brick durability. One of ways of sett ing time regulation lies in introduction of some stone-cutting waste in blast-furnace grained slag before grinding. The studies of stone-cutt ing waste infl uence on curing time, durability and structure formation of slag-lime binder and concretes on its basis are able to show mechanism of curing time regulation and it will work to correct technological parameters of construction items production. The phase composition is studied with help of the diff erential thermal, x-ray diff raction and microstructural analyses.
