Strengthening of Concrete by Recycling Parking Tiles as a Sand Replacement

Abstract

The usage of natural aggregates has expanded drastically as a result of day-to-day innovations and progress in the building industry, at the same time, the production of solid wastes from the demolitions of projects has increased to an equally high level. Because of these concerns, the concept of recycling demolition debris, such as parking tiles into new products became a reality in an effort to lessen the load of trash headed to landfills and to alleviate the shortage of natural aggregates used in concrete production. The destruction of various road's isn't the sole source of parking tiles debris, it's also produced in the production process. According to research, between 0 to 40 percent of the raw materials used in the production of tiles end up as landfill garbage. Ten percent of the fine aggregate was swapped out for powdered parking tiles powder. Concrete of the M20 quality was developed and evaluated. Different types of mixtures were designed by substituting crushed parking tiles for the coarse aggregates and fine aggregate in varying ratios. Experiments were conducted to determine the flow ability, compressive strength, split tensile strength, and flexural strength of concrete mixes including 7, 14, and 28 days of cured waste broken and Parking tiles powder. An increase in the proportion of replacement with parking tiles powder and shattered tiles improves work-ability, it has been found. Adding parking tiles aggregate to concrete at a proportion of up to 30% boosts the material's strength. The study evaluates the performance of parking waste tiles as a sand replacement. The experiment was conducted by substituting sand with at various proportions, ranging from 10% to 40%. The properties of the resulting parking waste tiles, including compressive strength, water absorption, and density, were measured. The results showed that the use of as a sand replacement material improved the compressive strength. The highest compressive strength was obtained at 30% replacement, while the lowest water absorption was recorded at 40% replacement. Therefore, the study suggests that can be used as a partial replacement for sand in production, leading to improved performance and sustainability.
