PENETRATION OF CHLORIDES INTO CONCRETE: ANALYSIS OF EXPERIMENTAL STUDIES
Article Sidebar
Main Article Content
Abstract
Reinforced concrete structures are exposed to an aggressive environment. In this case, combined mechanical and environmental impacts can act simultaneously, and their synergistic effects should be taken into account. This article presents and analyzes the test results on two different types of concrete and mortar. The capillary absorption of carbonized and non-carbonized concrete was determined. The influence of mechanical load on capillary suction has been studied. Moderate compressive load reduces the capillary suction coefficient, while capillary suction is enhanced by higher mechanical loads as microcracks form. The diffusion of chlorides was evaluated using a diffusion cell test. The diffusion coefficient in carbonized concrete is an order of magnitude higher than in non-carbonized concrete.
