Mesoscopic Model on Frost Resistance of Marine Concrete Subjected to Chloride Ion

CODEN: ACEMF9

Abstract

The properties of concrete subjected to freeze–thaw cycles in water, 10.5 g/L and 21.0 g/L Nacl solution, were investigated in this article. Based on the experimental results, the dynamic elastic modulus and compressive strength of concrete were measured during different numbers of freeze–thaw cycles. Then, the characterizations of the pore structure of concrete were analyzed on the basis of a mercury intrusion experiment. A mesoscopic model was presented based on the changes of pore structures for calculating the influence of chloride on the frost resistance of concrete. The results show that the contents of NaCl solution have a significant influence on the pore structure, compressive strength, and dynamic elastic modulus of concrete subjected to freeze–thaw cycles. The new mesoscopic model can help compensate for the lack of research on the effect of chloride diffusion on freeze–thaw cycles.
