Evaluating the Cracking Behavior of Recycled Tile Waste Aggregate Concrete
摘要
The use of recycled ceramic tile waste in concrete has gained widespread attention due to pressing concerns about the scarcity of natural resources and the management of construction and demolition waste. It contributes to the development of eco-friendly construction practices while attempting to reduce the environmental impact associated with tile disposal. This research primarily focuses on investigating the impact of replacing coarse aggregates in concrete with Recycled Tile Waste Aggregates (RTWA) on cracking behavior, an area that has not received much attention in previous research. A comparative study was conducted between beams with natural aggregates and RTW aggregates, specifically targeting the identified optimal replacement ratio of 20%. Three-point bending tests were carried out to systematically investigate crack formation, propagation, and failure mechanisms, providing insights into the material’s flexural performance. In conjunction with evaluating the crack patterns, compressive strength tests were carried out on cube specimens to gain an understanding of the material’s mechanical strength properties. The study reveals that the RTWA-replaced beam exhibits a lower incidence of cracks compared to the beam with natural aggregates. According to the results obtained, RTW concrete showed a 26% higher compressive strength than natural aggregate concrete and a 4.2% decrease in flexural strength performance. The findings of this research project offer the possibility of effectively integrating recycled tile waste aggregates into concrete production.
