Effect of Partial Replacement of Cement by Ground-Granulated Blast-Furnace Slag and Fine Aggregate by Marble Slurry on Properties of Concrete

摘要

The aim of this study is to evaluate the performance of partial replacement of cement (OPC- 43 grade) with Ground-granulated blast- furnace slag and Fine aggregate by Marble slurry a mineral admixture in concrete. GGBS is produced by quenching molten iron slag in water or steam, to produce a glassy, granular product that is then dried and ground into the fine powder. And Marble slurry is a waste product from marble industries constitutes one of the environmental problems all over world. In this study partial replacement of OPC (43-grade) by GGBS up to 20% by total weight of OPC and Fine aggregates up to 40% by Marble slurry. This study investigates the performance of concrete mixture in terms of compressive strength of cube, flexural strength of beam and splitting strength of cylinder for 7 days and 28 days respectively.
