Effects of mixing water salinity on the properties of ...

2020-10-20  Existing studies on SSC or seawater concrete have been largely limited to the use of mixing water with a salinity level close to the world-average ocean salinity. Against this background, the present paper reports the first ever systematic study on the effect of salinity of mixing water on the properties of concrete.

Quality of Water for Making Concrete: A Review of

2021-6-4  Pilar Alaejos and Miguel A. Bermudez have studied the effect of sea water curing on properties of reinforced cement concrete. Different tests conducted are, compressive strength, porosity, chloride penetration rate and capillarity. The result shows that, sea water curing does not affect compressive strength, or the porosity of concrete specimens cast with sulfate resistance cement. However, it increase the chloride concentration at the concrete surface which results hygroscopic effects and lead to water absorption and capillary suction. Chloride penetration coefficients are initially higher in sea water curing concretes,

Effect of Saline Water on the Properties of Concrete

Chemical analysis of the saline water was carried out before and after use. Temperature and pH of the saline water was monitored. Forty-Eight concrete cubes were cast of 150 x 150 x 150 mm size and tested for their compressive strength at 7, 14, 21 and 28 days. The setting time reduces with saline water. The concrete of FS, SF and SS at 28 days ...
