Water in GGBS concrete takes slightly longer to combine chemically to form hydration products, thus making GGBS concrete a little more sensitive to poor curing. For GGBS contents of up to 60%, curing periods as recommended in IS 326 and BS 8110 for Portland cement concretes are sufficient.THE EFFECT OF GGBS ON THE DURABILITY OF CONCRETE,10-09-1991· 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.A STUDY ON PARTIAL REPLACEMENT OF CEMENT WITH GGBS IN CONCRETE,dosage of percentage of replacement of cement with GGBS was found to be 40%, 40%and 50% in Ordinary (M20), Standard (M40) and High strength grade (M60) grades of concrete respectively. They also concluded that the partial replacement of cement with GGBS in concrete mixes has shown enhanced performance in terms of strength and durabilityAdvantages Of Ggbs In Concrete [vnd5jr9ze9lx],GGBS concrete will even provide better fire resistance. Limitations However, it is identified that there are still some hindrances that prevent the prevalence of its usage in local market. Technically speaking, GGBS concrete suffers from lower rate of strength development which isGround Granulated Blast Furnace Slag in Concrete and,Hence the use of GGBFS in concrete manufacture would give a light and brighter color to concrete unlike the dark grey color of ordinary cement concrete structures. This is an added advantage of GGBFS in terms of aesthetics. The typical properties of GGBS are given in Table-2. Table 2.
