Abstract
A simple, accurate, and rapid method of estimation of periclase in cem ent clinker and tricalcium silicate has been developed using chemical extraction followed by complexometric determination. The data obtained has been compared with the results of XRD. A good agreement was found between the two methods. The proposed method will be suitable for the estimation of free MgO in clinkers. It was also found that of the tot al MgO present in tricalcium silicate (C3S), about 1.5% gets into the C3S mineral and the rest crystallises out in the mineral form, as peri clase.
