Optimizing Concrete Strength with the Partial Replacement of Aggregate with Ceramic Tiles for Sustainable Construction

Abstract

ABSTRACT: The coarse aggregate replacement in part with crushed waste ceramic tiles was explored at varying percentages, ranging from 10% to 50%. Simultaneously, granite powder and ceramic tile powder were employed as substitutes for fine aggregate, each at a 10% replacement rate alongside the ceramic coarse tiles. As a result of continuous innovations and advancements in the construction industry, there has been a significant rise in the utilization of natural aggregates. The generation of solid waste from construction demolitions has also witnessed a substantial increase. Research indicates that approximately from 20% to 30% of materials produced in manufacturing plants end up as waste. To address the constraints of natural aggregate resources and mitigate construction waste, there is a pressing need to repurpose this waste material. Concrete of M25 grade was designed and subjected to testing. Mix designs for different combinations were formulated by altering the percentages of crushed tiles and granite powder in both coarse and fine aggregates. Experiments were conducted on several concrete mixes using variable volumes of discarded shattered tiles and granite powder during seven, fourteen, and 28 days of curing. These examinations included “workability assessments, compressive strength tests, split tensile strength tests, and flexural strength tests”. The results show that larger replacement percentages of granite powder and crumbled tiles boost workability. Additionally, the strength of the concrete exhibited an improvement, particularly with a 30% replacement of ceramic coarse tile aggregate. Explore the use of advanced ceramic composites with improved mechanical properties and durability for enhanced performance in concrete. Investigate the potential use of recycled ceramics or explore novel production methods that reduce energy consumption and greenhouse gas emissions, aligning with sustainable construction practices.
