Sugarcane bagasse ash can be defined as residue from the burning process of sugar cane bagasse. At the sugar mill, sugarcane bagasse is utilized as fuel for boilers used to process sugarcane. The burning process residue is mainly ash that contains considerably high silica content, therefore, it can be used as an alternative to substitute cement in concrete mixture. Sugarcane bagasse ash used in this research was previously sieved before utilized as concrete mixture constituent.<p>Sugarcane bagasse ash that is used was one that passed a 600 mm (0,6 pm) sieve. Besides sieving, the ash was not furthermore processed before used at the concrete mixture.<p>In this research, the effect of using sugarcane bagasse ash as a substitution of cement to the compressive strength of concrete is evaluated. The substitution percentages are 0 %, 5%, 10% and 15%. Curing process was conducted in water as curing media for planned curing period. Compressive strength of concrete containing sugarcane bagasse ash was compared to that of normal concrete (without sugarcane bagasse ash addition). Each concrete composition was tested for its compressive strength at 3, 7, 14 and 28 days.<p>Compressive test result shows that utilization of sugarcane bagasse ash does not give positive contribution to the compressive strength of concrete. Of all samples, normal concrete have higher compressive strength compared to sugarcane bagasse ash concrete. This is caused by the sugarcane bagasse ash particle size and degree of crystallinity. <br />
