In addition, cube specimens were also considered for quality control methods and compared against cylinders. Different UHPC mixtures, specimen shapes and sizes, fiber content, and curing regimes were adopted in this study. This seminar presents an assessment and development of the maturity method for UHPC as a quality control method to provide accurate strength predictions. Robust Methods for UHPC Early-Strength Determination and Quality Control for ABC - pdf of presentationÄescription: To take advantage of the high compressive strength of ultra-high performance concrete (UHPC), which can reach about 10 ksi after one day and about 20-22 ksi after 28 days of casting, a quality control method is needed to verify such strength at all ages.
