A relationship between compressive strength of a given concrete and its resistance to penetration by a steel probe fired into the concrete surface is presented to a compressive strength range varying from 50 MPa to 90 MPa using an alternative firing apparatus to the standard apparatus Windsor Probe Test System.engHigh Strength ConcretePenetration resistance testsIn situ compressive strengthWindsor Probe Test SystemAlternative Firing Apparatusjournal article
