Utilization Of Sugarcane Bagasse Waste As Green Concrete Using Local Aggregate

Abstract

Waste in the form of sugarcane bagasse which is processed by burning to turn it into ash has the same content as the main ingredients that make up Portland cement, namely silica (SiO2) and ferrite (Fe2O3), so that sugarcane bagasse ash can be used as a pozzolan which, apart from replacing some of the cement, can also increase the compressive strength of concrete. . The research method is testing concrete making materials and sugarcane bagasse ash. Tests were carried out for variations in the addition of sugarcane bagasse ash at 0%, 3% and 5%. The fine aggregate used in this research is fine coarse aggregate originating from Barito Sand. The coarse aggregate used in this research is coarse aggregate measuring 10 – 20 mm cotton crushed stone originating from Barito Kuala. The results of the concrete mix are made according to SNI 03-2834-2000 regarding the calculation of concrete mix planning (mix design). From the test results, it was found that the materials used, such as water, cement, sugarcane bagasse ash from Landasan Ulin and coarse aggregate crushed stone, 1-2 crushed cotton stones from Barito Kuala, can be made for a concrete mix proportion of K-250 kg/quality. cm2 varies starting from 0% or normal concrete, 3% bagasse ash and 5% bagasse ash.
