Abstract

Recently, interest has grown in using alternatives to cement and aggregates to improve concrete and reduce its environmental impact. This study explores the use of cherry pit waste (CPW) as a partial substitute for coarse aggregates in self-compacting concrete (SCC) at varying rates (0–25%). Rheological, compressive strength, and ultrasonic pulse velocity tests were conducted. The results showed that CPWs reduce flowability but increase cohesion. The 5% CPW mix achieved the highest compressive strength. All the mixes remained acceptable, with classifications from SF3 to SF1. Due to CPWs’ lower density, both wet and dry weights decreased, making this a viable lightweight concrete option.
Keywords: cheery pit waste (WCP); compressive strength; flowability; rheological properties; ultrasonic pulse velocity (UPV) cheery pit waste (WCP); compressive strength; flowability; rheological properties; ultrasonic pulse velocity (UPV)
