Portland Slag Cement | PSC Application | Advantage | Manufacturing Process | Use of GGBS

(IS.455.1989 )Portland Slag Cement, commonly known as PSC, is blended cement. ... It is created with a combination of upto 45- 50% slag, 45% – 50% clinker, and 3-5% gypsum. PSC has been voted as the most suitable cement for mass construction because of its low heat of hydration. Ground granulated blast furnace slag (GGBFS IS-12089.1987 Specification) is used commercially as a supplementary cementitious material in Portland cement concrete (as a mineral admixture or component of blended cement). Slag cement is used in virtually all concrete applications: Concrete pavements. Structures and foundations. Mass concrete applications, such as dams or retaining walls Reducing Thermal Stress in Mass Concrete. When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the hydrated cement paste (pozzolanic reaction), resulting in a more refined microstructure than that of a plain portland cement. The concrete using Ground Granulated Blast Furnace Slag (GGBS) has some disadvantages like as lower initial strength and higher dry shrinkage. #Portlandslagcement #PSC #slagcement #GGBFS #PSCcementapplication #useofPSC #cementplant #cement
