Abstract :

The construction industry is the largest consumer of natural resources which led to depletion of good quality natural sand (fine aggregate). This situation compels us to explore alternative materials and sugarcane bagasse ash, a waste industrial byproduct is one such material identified for use as a replacement of natural sand. Sugarcane bagasse ash (SCBA) generated from sugar mills is fibrous waste-product usually delivered to landfills for disposal. Using of sugarcane bagasse ash in concrete is an interesting possibility for economy and conservation of natural resources. This research work examines the possibility of using sugarcane bagasse ash as replacement of fine aggregate in concrete. We partially replaced 10%, 15%, 20%, 25% and 30% of natural sand with SCBA. We compared compressive strength, tensile strength and flexural strength with those of concrete made with natural fine aggregate. We also studied chemical properties of SCBA. The test results indicate that it is possible to manufacture concrete containing sugarcane bagasse ash with characteristics similar to those of natural river sand aggregate concrete, provided that the percentage of sugarcane bagasse ash as fine aggregate is limited to 10 percent.
