Abstract

Due to the growing quantity of solid waste resulting from building damage, it is suggested that roof tile waste could be used in mortar in place of sand. This study aims to determine the physical and mechanical properties of mortar produced with waste roof tile as one of the ingredients. In this investigation, 15%, 25%, 35%, and 50% of the roof tile weight was substituted for sand. The specimen is a cube measuring 5 x 5 x 5 cm, with a testing age of 28 days. Consideration was given to four forms of testing: compressive strength, tensile strength, water absorption, and mortar density tests. The results demonstrated that the unit weight of sand in both its loose and compacted states is greater than that of roof tiles. While roof tiles have a higher water absorption rate than sand (26.8% vs. 6.0%), the compressive strength of all roof tile mortar variations was greater than the 13.07 MPa of the control mortar. When more roof tiles are used in place of sand, mortar's tensile strength typically decreases. The ratio of tensile strength to compressive strength ranges from 1.61 percent to 2.49 percent, which is less than the 3.9 percent ratio of the control mortar. The average quantity of water absorbed by mortar with roof tiles is 8.3%, and the greatest amount of water is absorbed when 50% of the mortar is replaced with sand. Roof tiles with a 35% composition and a 7.7% water absorption rate are recommended as an alternative to sand. This form of roof tile mortar is nearly identical to Type M mortar, which can be used to create structural concrete. Roof tile waste has the potential to be used as a substitute for sand in mortar mixtures, it can be concluded.
