Concrete samples of 150mm x 150mm were cast using saline water of four different concentrations- 4g/L, 10g/L, 30g/L, 60g/L. All the four samples were cured by total submersion in pure water. The mixes were prepared in the laboratory in the ratio 1:2:4 of cement, sand and aggregates. The water: cement ratio taken was 0.5:1. For every 1 Kg of cement, 0.5
