Portland slag CII-S Portland fly ash Cement type. The main differences between OPC and PPC are written below. When slag cement hydrates, it reacts with sodium and potassium alkali and calcium hydroxide [Ca(OH)₂] to produce additional C-S-H. Why OPC and GGBS combination is Preferred? Nowadays PPC is used as a replacement to OPC. The slag cement with a wt. Blended cement is obtained by mixing OPC with mineral admixtures or additives like fly ash, slag or silica fumes. Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. These two type of cement differs from each other in terms of component, strength, heat generation, the percentage of several components, durability, grades, cost, eco-friendly nature, application, setting time, curing period etc. As seen in the Figure 1, for the pure portland cement concrete substantial reduction in the chloride permeability was obtained between the C35 and C40 . Slag is produced during the iron-manufacturing process. min. cement concrete is about 6 times higher than the slag cement concretes. Lafarge NewCem ® is a supplementary cementitious material (SCM).
