Abstract:

The possibility of using bottom ash and their combination as a fine aggregate in mortar was studied by performing experiments. These materials were used without applying any preprocesses, such as sieving and grinding. The physical and mechanical strength studies on mortar with natural sand replaced with bottom ash at 10, 20, 30, 40, and 50% were examined at constant workability. Test results showed that it can be seen in cement mortar 1:2, 1:3, and 1:5, 1:6 that up to 20% replacement of sand by bottom ash increases and compressive strength decreases gradually compared to reference mix, which may be due to filler effects of bottom ash. In addition, The mortar strength of all mixes considered in the study (i.e., 1:2, 1:3 and 1:5, 1:6) for all replacement levels of sand (within the range considered in this study) satisfies the average compressive strength of cement mortar of comparable mix proportion as IS Specification, Hence, bottom ash can be used with confidence as masonry mortar.
