Mesoscopic Transmission Model of Chloride Ions in Concrete Based on Coupling Influence between Multiple Mechanisms and External Load

CODEN: ACEMF9

Abstract

The durability of concrete structures in a marine environment depends on the migration speed of chloride ions in concrete. In general, marine concrete is under the effect of multiple mechanisms of chloride ions and external load (increase the density of internal cracks and affect chloride ion transport), and the single transmission mechanism or calculation model under the condition of external load has certain limitations. Simultaneously, the transport of chloride ions in concrete is closely related to its pore structure. Therefore, a mesoscopic model was presented based on changes of pore structures for calculating the influence of different transmission mechanisms on chloride and external loads. The results show that the new mesoscopic model has high accuracy in the short period of time and the comprehensive calculation of the simulation on chloride ion transport (especially for the presence of external loads).
