Calculation of theC3APercentage in High Sulfur Clinker

[摘要] The aim of this paper is to clarify the influence of the clinkerSO3on the amount ofC3A. The calculation of the cement phases percentages is based on the research work, Calculation of the Compounds in Portland Cement, published byBogue in 1929 .The usage of high sulphur fuels, industrial wastes, and tires changes completely the working condition ofBogue because the assumed phase compositions may change. The results prove that increasing the amount ofSO3in the low alkali clinker decreases the percentages ofC3Adue to the high incorporation of alumina in the clinker phases mainlyC2SandC3S. The correlation is linear till the clinkerSO3reaches the 2%. Over that the influence of the clinkerSO3became undetectable. A new calculation method for the determination of theC3Ain the high sulphur and low alkali clinker was proposed.
