Abstract
Concrete is commonly used as building material due to its high compressive strength and durability. Looking forward into the technologies, the use of recycled materials in concrete production has grown in popularity. For example, recycling of ceramic roof tiles waste as an aggregate in concrete will help to alleviate industrial waste disposal issues while also preserving natural aggregate supplies. In this work, unglazed fired roof tile waste (URTW) at 40, 50, and 60 wt% was investigated to potentially replace natural sand fine aggregate in producing new green concrete. The aim of this paper is to report on the mechanical properties of the new green concrete produced. A total of 12 concrete specimens, 100 mm × 100 mm × 100 mm each, were tested. Three concrete specimens were kept as control specimens, 9 specimens with URTW as fine aggregate at 40%, 50%, and 60% weight fraction as fine aggregates were accordingly prepared according to M25 grade of concrete (BS1881-108:1983). Eventually, all specimens were tested for its workability which is slump test (BS 1881:part 102), water absorption test and compressive strength by using compression testing. It was found that the strength gradually increases with the 40, 50, and 60 wt% of URTW as the fine aggregates. The strength achieved by the concrete (41.00 N/mm2 ) is above than the target mean strength of M25 (25.00 N/mm2 ). However, it is also observed that the use of URTW influence the workability of the concrete mixture, here the workability of concrete mixture with 60 wt% of URTW is reduced compared to 20 and 50 wt%. Thus, it can be concluded that the promising percentage of weight for URTW used as fine aggregate in the concrete mixture is at 50 wt%.
