Key Words anhydrite gypsum clinker cement 1.INTRODUCTION As it is well known the workability property of cement solutions depends on reaction rate of C 3 A with water and to justify this retarder raw materials are used. In cement industry natural gypsum CaSO 4 2H 2 O is the most effective raw material for this purpose.
Sep 01 2020 1. Introduction. Ground granulated blast furnace slag GGBS is a by-product of the blast furnaces in production of iron. GGBS can be used as a supplementary cementitious material to decrease the overall energy usage and carbon dioxide emissions in cement industry 12.It is expected that more slag could replace the clinker to make the blended cements.
