Abstract


This paper presents an experimental study on the durability properties of carbonated alkali-activated slag (AAS) concrete. An ordinary Portland cement (OPC) was also tested for comparative purposes. The durability properties were studied through the measurements of compressive strength, permeable voids, and water absorption and chloride permeation. The results indicated that the AASs showed higher compressive strength at early ages than the OPCs. Contrary, permeable voids and water absorption measurements were lower for AASs than for OPCs.
