INFLUENCE OF CEMENT AND MIX COMPOSITION ON CONCRETE DETERIORATION IN THE MARINE ARABIAN GULF ENVIRONMENT . PROCEEDINGS OF 3RD INTERNATIOAL CONFERENCE ON DETERIORATION AND REPAIR OF REINFORCED CONCRETE IN THE ARABIAN GULF, BAHRAIN, OCTOBER 21-24 1989. VOLUME 1.

This paper evaluates the durability performance of concretes made with Type V, Type I and blended OPC-blast (Ordinary Portland Cement) furnace slag cement using Dhahran limestone and Ras Al Khaima gabbro coarse aggregates, exposed to the splash zone marine environment of the Arabian Gulf. The study entailed making eleven mixes with water to cementitious materials in the ratio of 0.40 and cement factors of 400, 300 and 250 kg/cu mtr. The test specimens have been positioned on a especially erected concrete platform 1.2 m above the MSL which forms part of a national weathering exposure station located on the north side of the border station at the King Fahad Causeway. The results reported after two years of exposure show that significantly more scaling occurs in concrete made with Dhahran limestone compared with concrete made with Ras Al-Khaima gabbro. The scaling in blended OPC-blast furnace slag concretes is higher than in Type V/I cement concrete. At a depth of 0.625 inches, chloride concentrations were found to be 3 to 5 times higher in Type V/I cement concretes than in blended OPC-blast furnace slag concrete. Cement content has a pronounced effect on the scaling of concrete made with Dhahran limestone aggregates, and on chloride penetration in Type V/I cement concretes. Blended OPC blast furnace slags showed increased scaling for higher cement contents. For the covering abstract of the conference see IRRD 828897.
