PEMANFAATAN ABU SAWIT SEBAGAI BINDER PADA SELF- COMPACTING CONCRETE (SCC)

Abstract

This study analyse the workability and compressive strength of Self-Compacting Concrete (SCC) by using palm oil ash as mineral admixture for binder. Workability examined was flowability, fillingability, and passingability using a Slump Cone, V-Funnel and L-Box. Palm oil ash added in the mixture was 5%, 10%, 15%, and 20% from weight of the binder. Research showed the flowability and fillingability of SCC decreased with addition of palm oil ash in the mixture. Passingability increased with percentage of ash addition in the mixture. The optimum of flowability using T50 and slump flow was obtained at mixture with using 10% addition of palm oil ash. While the optimum flowability was determined for mixture with 5% ash using V-Funnel. Passing ratio of all mixtures was in the range from EFNARC, 2002. The maximum compressive strength of SCC was 34.82 MPa at 28 days concrete age for mixture using palm oil ash of 10%.
