The quality of cement can be evaluated firstly, by measuring physicochemical parameters of the raw materials, and intermediate products (raw, flour, clinker), which is formed during the manufacturing process, and the cement as a final product. Secondly, by the measurement of physico-mechanical parameters: compressive strengths at early age and long-term, flexion.... etc.. To reduce the number of experiments, orient the use of clinker and predict the quality of cement, we used a mathematical model of multilinear regression to find a correlation between the chemical parameters of clinker and compressive strengths at 2, 7 and 28 days of portland cement without adding CPA. The results of the statistical and experimental study are highly predictive and reliable.
