The effects of sugarcane waste and bagasse ash additives on concrete block mechanical properties with non-destructive test methods

Abstract

One of the main problems in providing housing in Indonesia is the high cost of building construction and materials. So far, various studies have been carried out, but alternatives to efficient construction techniques and the provision of building materials in large quantities have not been found. This can provide an alternative to utilizing industrial wastes that are left unattended. Industrial waste which is used as a mixture for concrete, bricks, concrete block, etc. is able to increase the compressive strength. One of the raw materials that can be used is bagasse waste. In Indonesia, a lot of bagasse waste comes from sugar factories. For the factory, bagasse is a waste that is quite troublesome because when the dry season arrives, the bagasse can burn. In addition, the utilization of bagasse waste is still not optimal. Thus, there is a need for research on the utilization of bagasse waste. The objectives of the discussion were: 1) to analyze the effect of bagasse ash with variations of 0%, 5%, 15%, 25% and bagasse fiber with 10% variation; 2) to determine the optimum value of using bagasse fiber ash and bagasse fiber. The research method in this research was quantitative research through experimental. Analysis of test result data was carried out using comparative method and quantitatively. The result of this research was the UPV and Hammer tests show some of the same phenomena. One of them was the difference in the compressive strength value of normal concrete blocks with other variations that are not too far from each other. However, for the bagasse ash variation of concrete block, the bagasse ash concrete block compressive strength was the highest at 5% variation (UPV), while in the Hammer test, its highest value was in the 15% of bagasse ash variation at 28 days-old testing.
