Abstract: This research aimed to study on compressive strength and water permeability of concrete mixed with ground bagasse ashes having different loss on ignition (LOI). Three different sources of bagasse ash were ground separately until the particles retained on a sieve No. 325 of 2.5?0.5 percent by weight. Portland cement Type I was partially replaced by ground bagasse ashes at the rates of 10, 20, 30 and 40 percent by weight of binder. All concrete mixtures had binder content of 300 kg/m3 while water to binder (W/B) ratio was kept at 0.60. The slump of fresh concrete was controlled between 5-10 cm by using superplasticizer. Compressive strength and water permeability of concretes were tested at the ages of 28 and 90 days. The results showed that the use 10 and 20 percent of ground bagasse ashes to replace Portland cement Type I could produce the compressive strength of concrete higher than that of the control concrete and reduce the water permeability to be lower than that of the control one. Concrete containing 20 percent of ground bagasse ashes by weight of binder gave the highest compressive strength and lowest water permeability of concrete. Concretes containing 30 and 40 percent of ground bagasse ashes by weight of binder exhibited the lower of compressive strength but had lower water permeability than that of the control concrete. In addition, the above results also suggested that LOI of ground bagasse ashes between 9.1-19.4 percent does not play any significantly role on the compressive strength and water permeability of concrete.
