Investigating the correlation between ultrasonic pulse velocity and compressive strength in polyurethane foam concrete

Abstract Using waste polyurethane foam as a partial replacement for natural coarse aggregates in concrete provides an eco-friendly solution by reducing waste and conserving natural resources. However, the strength behavior of polyurethane foam concrete differs from conventional concrete. To ensure e...
