for normal strength concrete (NSC) is based on cylinders or cubes with 150 mm (6 in.) minimum dimensions.1 However, retaining these specimen sizes as a standard for high-strength concrete (HSC) beyond 75 MPa (10,880 psi) and ultra-high-performance concrete (UHPC) may cause problems. Two primary issues arise when using standard compression
If the concrete design strength is 6,000 psi or greater, the initial curing temperature must range from 68 - 78 degrees F. Specimens should be shielded from direct sunlight or radiating heating devices, if used. A minimum-maximum thermometer shall record the temperature of the initial curing period, and then recorded upon retrieval of cylinders
