Abstract

In the present work, the interlocking blocks was modified by partial substitution of lateritic soil (LS) with bagasse ash (BA). The effect of ordinary Portland cement (OPC) to LS ratio of 1:3 1:5 1:7, 1:9 and 10, 15 and 20 wt.% of BA content on the engineering properties of interlocking blocks was investigated. The chemical and physical properties of LS and BA were determined by X-ray fluorescence spectrometer, sieve analyzer, and scanning electron microscope. The engineering properties of modified interlocking blocks were compared with interlocking blocks without replacement of BA. The results show that BA was a porous material with high water adsorption. The adding BA to interlocking blocks decreased compressive strength, dry density values and lead to high void within interlocking blocks structure. The interlocking blocks at OPC:LS ratio of 1:5 with 15 wt.% of BA were perfectly suitable for inside and outside building construction. ฉ 2019, Thai Society of Higher Eduation Institutes on Environment.
