Environmental variables in the concrete saturation degree modelling

Resumen

Aiming to facilitate the calculation of the concrete saturation degree, and assuming that it is an important factor in the diffusion coefficient of chloride ions inside concrete, mathematical models that exempt local measurements were developed. Concluded studies attest the influence of the saturation degree in the diffusion coefficient, and a proposed model enables the calculation of the ion diffusion coefficient, considering the variations of the saturation degree for each type of concrete. The models were developed through statistical analysis of environmental variables which affect the variation of the saturation degree. As a conclusion of this study, fifteen models were developed based on the multiple linear regression, which estimate the seasonal average saturation degree of each type of concrete, generating a maximum percentage error less than 5%.
