Abstract
As the economy and industrialization have grown, the foundry industry has produced a significant amount of ceramic mold casting waste (CMCW). To promote resource utilization, this study investigates recycling CMCW as a partial replacement for lightweight aggregates in lightweight concrete. This study investigated the durability of lightweight concrete mixes with varying CMCW content, using surface electrical tests, ultrasonic pulse velocity measurements, non-steady state accelerated chloride penetration tests, and carbonation resistance experiments. Then, the results indicate that a lightweight concrete containing 80% CMCW exhibited greater density and uniformity, greater resistance to chloride ion penetration and better resistance to carbonation. These findings suggest that CMCW can be an effective and sustainable replacement for lightweight aggregate in lightweight concrete, improving their durability and environmental performance. This research contributes to the development of sustainable construction materials and provides insights for the use of CMCW in the foundry industry.
期刊介绍:
For concrete and other cementitious derivatives to be developed further, we need to understand the use of alternative hydraulically active materials used in combination with plain Portland Cement, sustainability and durability issues. Both fundamental and best practice issues need to be addressed.
Magazine of Concrete Research covers every aspect of concrete manufacture and behaviour from performance and evaluation of constituent materials to mix design, testing, durability, structural analysis and composite construction.
