摘要：

Investigates the influence of concrete strength on the measured core compressive and tensile strengths of three large columns. The lower strength concrete had larger variability in strength than the higher strength concretes. Measured compressive and tensile strengths from the core specimens were found to be between those strengths measured on cylinders cured in air and those cured in water The permeability was found to decrease significantly with the increased matrix densities of the higher strength concretes.
