An overview on rheology, mechanical properties and durability of high-volume slag used as a cement replacement in paste, mortar and concrete

Disposal of slag resulting from pig iron process is one of the main eco-friendly confrontations. This confrontation is still increasing with the increase slag content and diminishing the landfill space latitude. Accordingly, studies have been achieved to reuse granulated ground blast-furnace slag (denoted as slag) by way of high-volume (HVS) as a cement replacement in building materials. This article offerings a review summary of the earlier investigations which concentrated on using HVS (≥45%) as a part of cement in conventional paste, mortar and concrete mixtures. Fresh properties, mechanical properties, durability and other properties of paste, mortar and concrete mixtures containing HVS as a cement replacement have been reviewed. Furthermore, curing conditions as well as different additives used to improve some properties of HVS system such as nano particles, cementitious materials, and other materials have been summarized.
