EARLY STRENGTH TESTING OF CONCRETE CORES AND CYLINDERS

During the 1989 construction season in Wisconsin, six projects, which were built by four different concrete paving contractors, were studied to assess the in situ early strength of concrete pavements, the early strength of lightly insulated field-cured concrete cylinders, and the 28-day strength of paving concrete. The projects were also studied to establish the relationship between cylinder and in situ strength typical on paving projects in Wisconsin. The results of testing over 1,500 individual cores and cylinders indicate that most pavements constructed in warm weather attain compressive strengths of 20.7 MPa (3,000 psi) to 24.1 MPa (3,500 psi) in 3 days or less, approximately 95% of the paving grade concrete has a 28-day compressive strength of more than 27.9 MPa (4,050 psi), and the compressive strength of lightly insulated cylinders cured in the field provides a reasonable measure of the in situ compressive strength of the pavement as measured in core tests.
