Description
Summary:•Desliming significantly affects the UPV and UCS properties of CPB.•Binder type plays an important role for UCS and UPV of CPB.•The UPV of CPB increases with increasing binder dosage and reducing w/c ratio.•There is a linear relation between UCS and UPV of CPB.•The UCS of CPB can be estimated by ultrasonic UPV test. Ultrasonic pulse velocity (UPV) test is one of the most popular non-destructive techniques used in the assessment of the mechanical properties of concrete or rock materials. In this study, the effects of binder type/dosage, water to cement ratio (w/c) and fines content (
