Pengaruh Pemanfaatan Abu Tumbuhan Perumpung Terhadap Peningkatan Kuat Tekan Beton K300

Keywords: Trunk Ash, Perumpung, K300

Abstract

Perumpung (Eulalia japonica) is a wild plant that usually grows on the banks of river. The locals consider this plant as a waste/pest, but the authors are interested in researching perumpung because they are similar to bamboo, sugarcane and other fibrous plants. In this study, the authors aims to compare the compressive strength of normal concrete with the compressive strength of concrete added with Perumpung ash at 28-days-old K-300. The study used a cube-shaped test object (15 x 15 x 15 cm) with 6 samples for each condition. The total number of test objects is 48, which consists of 8 conditions, namely normal conditions and 5%, 7.5%, 10%, 12.5%, 15%, 17.5% and 20% addition of perumpung ash by cement weight. The results obtained that the compressive strength of 28-days-old concrete under normal conditions was 316,060 kg/cm2 and the addition of 5% ash was 331.583 kg/cm2, 7.5% was 337.181 kg/cm2, 10% was 341.813 kg/cm2, 12 ,5% is 347,045 kg/cm2, 15% is 353,889 kg/cm2, 17.5% is 311,160 kg/cm2 and 20% is 298.44 kg/cm2. From the results above it can be concluded that the addition of 15% Perumpung Ash to the concrete mixture increases the maximum characteristic concrete compressive strength by 353.889 kg/cm2.
