Description
C Arvind Kumar and colleagues tested coal bottom ash in 2026 as a partial sand substitute in eco-efficient concrete. Thermal plants landfill most bottom ash, while natural aggregate mining depletes river and quarry sand. Mixes replaced river sand or quarry sand with ash from 0% to 100%, tracking workability, compressive strength, and split tensile strength over curing.
Workability fell as ash content rose. River-sand mixes stayed within about 5% of control strength at later ages, while quarry-sand mixes lagged 6% to 25% at 28 days but closed to near control by 180 days. Gradient boosting predicted strength best at R-squared 0.99 within the dataset. Bottom ash thus offers a durable, waste-cutting aggregate option, pending broader validation.
