PFA of at least 25% or GGBS of at least 60% for a matter of simplicity and consideration of adequate safety margin. GGBS is increased as the level of GGBS is increased but after an optimum point, which is *55% of the total binder content, further addition of GGBS did not improve the compressive strength of concrete. GGBS replaces a substantial proportion of normal cement (Ordinary Portland Cement) in RMC. In short, Harmonized Code is a common term in global trade language, and it’s one of the most important elements to bring standardization to international trade. – GGBS is a slag waste product from steel plants, which is subsequently processed.
