| Summary: | Abstract This study explores the compressive performance of a composite material composed of cement, sand, glass fiber, and bottom ash (BA) derived from a refuse-derived fuel (RDF) incineration facility. The objective was to identify the optimal mix ratios for incorporating BA and glass fibers into a soil–cement matrix to enhance strength characteristics. A series of unconfined compression tests were carried out on specimens cured over different periods, with evaluations focusing on strength gains after 90 days. The samples were prepared using Bangkok construction sand at an optimal moisture content of 6.19%. Glass fiber was added in volumetric proportions of 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%, with fiber lengths of 3, 6, and 12 mm. Cement content was varied at 2%, 4%, 6%, 8%, and 10% by dry weight, while BA was introduced in volumes of 5%, 10%, 15%, 20%, 25%, and 30%. All specimens underwent curing for 7, 14, 28, 60, and 90 days before testing. The analysis identified 8% cement, 1.0% glass fiber at 6 mm length, and 20–25% BA as the most effective combination for maximizing compressive strength within the 28–90 day curing range. These findings suggest the feasibility of using glass fiber and RDF-derived bottom ash as sustainable additives in cementitious mixtures, contributing to material circularity and reduced cement demand in Thailand’s construction sector. |
