Abstract

Blast -furnace slag cement (CEM III) has a wide range of acceptable Cl- content according to EN 197- 1: 2012. This makes possible to use alternative fuels for the production of cement, which can increase the chlorides content in the clinker. However, it raises several new research problems,among them the problem of increase of the risk of Cl-penetration intensity due to the higher concentration of chlorides in cement , presented in this paper. Studies have shown that after a short hardening time (28 days) the rate of diffusion of chloride ions increases slightly with the increase in the content of chloride s in the cement CEM III, but after full stabilization of concrete properties (1 year), the content of chloride s in cement CEM III practically does not affect the diffusion rate of chloride ions in concrete.
