Abstract

Previous studies have shown that sugarcane baggase ash (SCBA) can be considered as a pozzolanic material due to its chemical composition. Thus SCBA added replaces the same amount of cement which lessens the main building material. Due to this, percent addition of SCBA in the concrete mix is proposed so that there will be no reduction in binding materials. In this study, crystalline SCBA was used as an additive in the concrete mix. The effect of SCBA as an additive on workability and compressive strength of concrete were investigated. Five different percent weight of cement addition of SCBA (0%, 5%, 10%, 15%, and 20%) at water-to-binder ratio of 0.5 was casted at 6 in. by 12 in. cylinders. Curing periods of 28 and 56 days were considered to assess the pozzolanic reaction in the concrete. Each addition has five specimens each which totals to 50 specimens overall. The slump was determined to be inversely proportional to the amount of SCBA added, such that when SCBA added increases, slump decreases. Compressive strength test results showed an optimum SCBA addition at 10%.
