of the aggregate is lower than the residual mortar and the specific gravity of the aggregate is higher than the residual mortar. Yet, this mechanical grind-ing method typically consumes a large amount of grinding energy and can be cost-inhibitive to the production of RCA concrete [16, 20-21]. The cost of grinding may be relatively higher than ...

An aggregate is produced from waste glass which is initially crushed to a granular state and is thereafter roughened at its surfaces and rounded at its edges. This result is obtained by a grinding treatment. The aggregate can be used for concrete. It allows an excellent adhering of the cement and it gives practically no rise to the danger of injury during the handling thereof.
