Correlation of ultrasound pulse velocity with Mechanical properties and water absorption in Phosphogypsum- crushing sand-lime-cement building bricks

The present work focuses on the ultrasonic pulse velocity of crushing sand ?lime-cement-phosphogypsum building bricks produced under a static compaction of 20MPa. It is observed that these bricks have sufficient Ultrasonic pulse velocity Tests were also conducted to study the relationship between ultrasound pulse velocity (UPV) with strength of bricks.. The results suggest that compressive and flexural strength values may approximately be determined without a destructive testing by using the non-destructive UPV measurements.
