title: Calculation of the c(3)a percentage in high sulfur clinker.
abstract: The aim of this paper is to clarify the influence of the clinker SO(3) on the amount of C(3)A. The calculation of the cement phases percentages is based on the research work, Calculation of the Compounds in Portland Cement, published by Bogue in 1929 .The usage of high sulphur fuels, industrial wastes, and tires changes completely the working condition of Bogue because the assumed phase compositions may change. The results prove that increasing the amount of SO(3) in the low alkali clinker decreases the percentages of C(3)A due to the high incorporation of alumina in the clinker phases mainly C(2)S and C(3)S. The correlation is linear till the clinker SO(3) reaches the 2%. Over that the influence of the clinker SO(3) became undetectable. A new calculation method for the determination of the C(3)A in the high sulphur and low alkali clinker was proposed.
