An Experimental Investigation on Concrete in Marine Environment (Sea Water)

In this present investigation, the durability studies of concrete in marine environment were determined. The cements like OPC, PPC and PSC was used to make the concrete. The physical property such as fineness, setting time, specific gravity etc for cement and fineness modulus, water absorption etc for aggregates was calculated. Mix design for normal concrete M35 was calculated based on trial mixes and code IS: 10262-2009. The compressive strength of concrete was calculated for M35 concrete by using OPC, PPC and PSC at 3, 7, 28, 60, 90 and 120 days. The curing of specimens was done in normal water and sea water after casting. The split tensile and flexural strength of concrete was calculated for M35 concrete by using OPC, PPC and PSC at 3, 7, 28, 60, 90 and 120days. The curing of specimens was done in normal water and sea water after casting. Finally, we were compared all the results and concluded that PSC (Portland slag cement) was gave better durability results to compare with other cements.
