of GGBS in concrete is limited to 50%. [24]. In this research, the effects of the partial replacement of cement with GGBS on the engineering properties of con-crete under different curing conditions have been studied. The use of GGBS in concrete tends to slow down the early-age strength, which limits its use in the fast-track con-

It is suggested that GGBS is generally beneficial in extending the life of concrete, and that this effect is especially important where the attack is the result of the movement of aggressive ions. For example, partial replacement of Portland cement by GGBS generally increases the resistance of concrete to sulphate attack and chloride attack.

THE EFFECT OF GGBS ON THE DURABILITY OF CONCRETE

GGBS (Ground Granulated Blast-furnace Slag) is a cementitious material whose main use is in concrete and is a by-product from the blast-furnaces used to make iron. Blast-furnaces operate at temperatures of about 1,500°C and are fed with a carefully controlled mixture of iron ore, coke and limestone.
