Effects of Sodium Chloride Solutions on Compressive Strength Development of Concrete Containing Rice Husk Ash

The study investigated the effects of sodium chloride (NaCl) solutions as curing medium at concentrations of 5% and 10% on compressive strength of concrete cubes containing 5% rice husk ash (RHA). Concrete cubes containing 5% RHA in NaCl solutions show early compressive strength increase at 3 and 7 days over control cubes; at 28 days concrete cubes containing 5% RHA cured in NaCl solutions recorded higher strength loss compared to control cubes.Keywords: Sodium chloride, concrete, compressive strength
