LONG TERM EXPOSURE OF PORTLAND LIMESTONE CEMENT CONCRETE, CONTAINING OR NOT MINERAL ADMIXTURES, IN COMBINED CHLORIDE AND SULFATE ENVIRONMENT
Original language description
In this paper the long term behaviour of limestone cement concrete, stored in chloridesulfate environment, was investigated. Concrete specimens were prepared by using an ordinary Portland cement and two different Portland limestone cements, as well as natural pozzolana, fly ash, blastfurnace slag or metakaolin, and were stored in solutions of various sulfate and chloride contents at 5 o C. Visual assessment, mass measurements and XRD analysis took place. The higher contents of limestone in cement and ofsulfate in storage solutions resulted in more intensive concrete damage. Thaumasite was the main deterioration product. The use of mineral admixtures improved the behaviour of limestone cement concrete. After 24 months of exposure, chlorides delay the deterioration of limestone cement concretes caused by sulfates. After 55 months, the presence of chlorides led to a greater mass loss. The specimens containing mineral admixtures showed more intensive deterioration at 24 months when chlori
