Ground Granulated Blast Furnace Slag (GGBS)

The use of 100% recycled glass as aggregates in architectural mortar is regarded as an environmentally friendly, cost-effective and attractive feature for construction applications due to the characteristics of glass as aesthetic pleasing, impermeability, chemical resistance properties. The need to use white cement for architectural products, in large quantities, may increase the overall cost of production. On its own, ground granulated blast furnace slag (GGBS) hardens very slowly and, for use in concrete, it needs to be activated by combining it with Portland cement. A typical combination is 50% GGBS with 50% Portland cement, but percentages of GGBS anywhere between 20 and 80% are commonly used.
