Abstract:

The investigation aimed to adopt sea water both for mixing and curing of concrete as the potable water is a scarce commodity on the planet Earth. At least sea water can be adopted in the construction industry as an alternative ingredient to potable water. Two concrete mixes viz, M30 and M35 using ordinary Portland cement (OPC) of 53 Grade as per the Guide lines of concrete mix proportioning with a slump of 100 to 150mm were considered. The mixes were prepared with “Potable water mixing and Sea water curing” & “Sea water mixing and Sea water curing”. A total specimen of 54 cubes, 54 cylinders and 54 beams including specimens for reference concrete were cast for both the mixes and exposed to 7days, 28days and 90days period of curing. The compressive strength behaviour, modulus of rupture and flexural strengths were investigated. The reference concrete was prepared with OPC using only potable water both for mixing and curing. The study reveals that there is no considerable reduction in compressive strength due to mixing of sea water and also due to mixing and curing with sea water compared to its target strength.
