Abstract:
The objective of this study is to evaluate the use of the Windsor probe test (ASTM C 803) to nondestructively determine the in situ compressive strength of normal and high-strength concrete. Tests were performed on 11 mixes with strength varying between 2240 and 18,820 psi (15 and 130 MPa). Two types of probes were utilized. The probes were made of a special high-strength alloy steel and had similar dimensions. For stress relief purposes, one probe type was baked for 3-1/2 hr while the other type was baked for 7 hr. The Windsor probe test was found successful in predicting the in situ compressive strength of normal and high-strength concrete up to 17,080 psi (120 MPa).
