Abstract This research studied the infiltration effects of chloride in concrete mixed with rice hull ash, dark husk ash and crushed dust to replace sand. The experiment carried out by making cylindrical concrete specimens with mixture of rice hull and dark husk ash instead of cement at the consequent percentages of 0, 10, 20, and 30 by weight and also the use of crushed dust instead of sand at the consequent percentages of 0, 10, 20, and 30 by weight. These concrete specimens have been soaked in marine environment at Cha-Am Beach, Petchburi province of Thailand for 90 days, tested for chloride infiltration in the concrete specimens by Colorimetric technique. The finding stated that chloride infiltration in all concrete samples was at 50% compared with the standard concrete. The best resistance of chloride infiltration was the one sand 10% replacement of crushed dust. According to the study, it showed that concrete specimen with rice hull ash and dark husk ash mixture caused Pozzolanic reaction effecting for more density, durability and thus decreasing of chloride infiltration in long term.
