Different degree of axial non-destructive compressive and tensile loadings are applied on cement mortar to study the influence of continuous loading on speed of carbonation and chloride ingress. Results show that within the range of the applied forces, compressive or tensile loading decreases or increases the ingress speed of CO2 and Cl-, respectively. Comparing with that for carbonation, influence of loading on speed of Cl- ingress is more obvious. In comparison to that of tensile loading, compressive force may lead to more significant impact on transport properties.
