摘要: This study aimed to explore the feasibility of using cement blended with ISSA as cementitious materials in production mortars recycled CRT glasses fine aggregates. For comparison purposes, fly ash (FA) and ground granulated blast furnace slag (GGBS) were also used. Fresh hardened properties mortars, well potential lead (Pb) leaching investigated. The experimental results showed that incorporation replace reduced workability, density compressive strength but increased water adsorption, drying shrinkage flexural mortars. influence different mineral admixtures on was closely related their pozzolanic activities adsorption abilities. superior FA GGBS enhancing reducing Pb mortar samples. It is noteworthy from samples prepared both glass greatly it complied local regulatory limits, increasing replacement ratio by led a corresponding reduction leachate concentrations mainly due precipitation ISSA.
