 Use of GGBS significantly reduces the risk of damages caused by alkali–silica reaction (ASR), provides higher resistance to chloride ingress — reducing the risk of reinforcement corrosion — and provides higher resistance to attacks by sulfate and other chemicals.GGBS cement can be added to concrete in the concrete manufacturer's batching plant, along with Portland cement, aggregates and water.The normal ratios of aggregates and water to cementitious material in the mix remain unchanged.
