Effect of Ceramics Wastes on the Mechanical Properties of Porous Concrete

Aims This study examined the impacts of leftover ceramic tiles in porous concrete to determine whether ceramic tile was a suitable aggregate for making concrete. This drives the purpose of this research which is to identify the effect of the possible use of waste-broken tiles in solid state and the powdered state on the properties of the porous concrete and how the combination of both crushed tiles as coarse aggregate and fine aggregate could effectively work in the hardened porous concrete. Background Without regard for potential reuse or recycling, the amount of ceramic tile in Nigeria has been rising. Due to the limited amount of land, the risk to public health is increased. Finding new landfill-free disposal methods can help to address the rising issue. Continuous reliance on traditional resources for concrete is also causing a shortage of those materials, which raises the cost of construction. Objective The physical properties of the crushed waste ceramic tiles and the mechanical characteristics of the concrete with ceramic tile aggregate were examined to meet the goal of this study. And to compare the results of the concrete made with ceramic tiles and those made with regular aggregate. Methods To achieve the objectives of this research, a series of laboratory experimental procedures were conducted then numerical calculations were done to derive some properties of the aggregates used in the concrete mix. Broken, trash, and abandoned tiles are the source of waste ceramic tiles. Both fine and coarse natural aggregates were completely replaced. A total of 60 cubes were made and evaluated for compressive strength ( f c ) at 7, 14, 21, and 28 days using a nominal mix ratio of 1:2:4 and a water-cement ratio of 0.55. Results From the series of experiments, it was discovered that the strength of the porous concrete decreased with the increase in the number of ceramic tiles. The results showed that at 28 days the f c was 20.14N/mm 2 with 0% ceramic tile coarse aggregate and 14.30N/mm 2 at 20% ceramic tile coarse aggregate. Conclusion This research concludes that the control sample has higher strength and durability than ceramic tiles and recommends that ceramic tile can be used as an alternative construction material for fine and coarse aggregate. With the addition and increase in the percentage of ceramic tile coarse aggregate, the compressive strength of the concrete decreases. Ceramics tiles in concrete reduced the weight of the porous concrete when compared to the concrete bearing crushed granite. Other Though the strength of the porous concrete decreased with the increase in the ceramic tiles, the sustainability aspect of this research must not be overlooked as the concrete is suitable and the use of waste ceramics tiles has a great positive effect on the environment.
