Properties of Concrete Blocks Made from Sugar Mill Waste

Abstract. This research is an experimental study of the properties of concrete blocks made from sugar mill waste. The properties that are reviewed are weight, water absorption, and compressive strength. The concrete blocks were made with five treatments for sand substitution with sugar mill waste (SMW) which were controls B0 (0%), B1 (6.25%), B2 (12.5%), B3 (18.75%) and B4 (25%) with a ratio of cement water of 0.4. Each treatment group was 30 samples so that the total sample was 150. The results showed that a high percentage of SMW caused a decrease in the weight of the blocks and increased water absorption. The addition of SMW on the aggregate affects the compressive strength of the blocks. A high percentage of SMW causes a decrease in the compressive strength of concrete blocks. The results of the statistical analysis showed that the addition of 12.5% SMW (B2) had an effect on the weight and absorption of the blocks, while the change in the compressive strength of the concrete block occurred with the addition of 6.25% SMW (B1)
