Relationship between sorptivity coefficients of concrete as calculated from the evolution of water uptake versus t0.5 or t0.25
Abstract
Sorptivity is a transport index to address the durability performance of concrete. Cementitious materials generally demonstrate anomalous capillary absorption (or imbibition) reflected by a non-linear evolution with t(0.5). A more accurate description of the transport process and a best fitting with experimental results are achieved with the novel approach based on the hygroscopic nature of concrete considering a linear progression with t(0.25). To take profit of past and present literature referring to the traditional approach, comparisons are to be made possible with an appropriate correlation between the coefficients obtained from both approaches (traditional and new). This paper presents such correlation between sorptivity coefficients of concrete as calculated from relationships of water uptake with t(0.5) and t(0.25). The comparison considers both the mathematical correspondence and the fitting to data produced in 6 different laboratories. An excellent relationship independent of the mix features is presented, with special consideration of the testing time.
