Abstract: In this work, a statistical model was determined to predict the compressive strength of calcium sulfoaluminate concretes cured under different solutions: distilled water, tap water, 0.5 N HCl, and 0.5 N H2SO4. The different storage solutions and time were the independent variables in the study involving mechanical aspects and durability approaches. The analyzes were developed using the multiple linear regression statistical method. The multivariate power function model was expressed as a function of time for the different experimental conditions used in the manufacture of the mixtures such as the gravel/sand and the water/cement ratio. The equations gave results for the estimation of compressive strength that fit correctly with the experimental results. The results indicate that the models mostly explain the variability of the strength in the mixtures in the ranges of 89-99%, except for curing in H2SO4 where it only adjusts to 33%, evidencing the deterioration suffered by the specimens under this attack.
