Abstract

Concrete is in an ever-increasing needs, making the other composites such as cement and other mixing materials such as coarse aggregate, fine aggregate, water, and other elements increased too. Within the current condition, the materials obtained from nature is decreasing in amount due to exploitation. Various experiments are conducted so as to find alternative natural source to substitute concerete mix composites. There are many sugarcane bagasse scattered around—as Indonesia is one of the biggest sugar producer—and it leads to an experiment to use sugarcane bagasse as a concrete composite. A limbah that was once not valuable now can be beneficial. Concrete mix of sugarcane bagasse ash was added in various proportion. In this case, the bagasse ash is used as an alternative for cement. A variation used in this study is 0%, 8%, 10%, and 12%. The testing object was cylindre 15 cm x 30 cm and compressure strength planningf’c ± = 14,5 MPa (K 175) the concrete’s compressure strength is then correlated in 28 age days. From the research conducted, after underwent 7 days treatment, it is obtained that hasil kuat tekan beton of 28 days old with additional 0%, 8%, 12% of sugarcane bagasse ash in order is 18,17 Mpa, 15,04 Mpa, 10,03 Mpa, 8,62 Mpa. The result shows that the kuat tekan experienced some decrease along the increasing addition of sugarcane bagasse ash in the composites. This also indicates that sugarcane bagasse ash can not be used as concrete composites.
