Abstract: As with other types of concrete mixtures, construction with high-strength concrete requires assurance that sufficient levels of in-place strength are reached at specific times. An experimental investigation of concrete with compressive strengths in excess of 6,000 psi was undertaken to investigate the application of combining the maturity and the pullout test methods for evaluation of greater in-place concrete strengths than previously reported. Relationships are reported between pullout test and compressive strength results for several mixtures, and the logarithm of maturity and the pullout test results for a mixture cured in two different environments.
