Short-Term Mechanical Properties of High-Strength Concrete

High-strength concrete (HSC) short-term mechanical properties were to be determined through a comprehensive experimental program. Rupture beam modulus and two different concrete cylinder sizes with three different target compressive strengths with a 10 to 18 ksi (69 to 124 MPa) range were subjected to three different curing durations and methods. To improve predictive equations for HSC rupture modulus and elastic modulus, test results were combined with data from the literature. Cylinders moist-cured for seven days exhibited the highest compressive strengths of the three different curing methods at the ages of 28 and 56 days. The lowest compressive strength, in contrast, generally resulted in one day heat curing. It was shown in the study that a 0.2 Poisson's ratio can be adequately used for HSC.
