HIGH-COMPRESSIVE-STRENGTH CONCRETE

摘要

The information contained herein constitutes the third and final report on high-compressive-strength concrete. The first report consisted of a review of the state of the art (Technical Documentary Report No. AFSWC-TDR-62-56). In phase two approximately 150 mixtures were proportioned to study the effect of mixture variables on the ultimate strength (Technical Documentary Report No. RTD TDR-63-31140 ). In this report are presented the results of the previous two phases, and results of physical and thermal tests of high-strength concrete including creep, shrinkage, thermal properties, heat rise, and stress-strain relations. Procedures for proportioning, mixing, placing, using, testing,, and inspecting high-strength concrete are discussed as well as the practical application of high-strength concrete to structural works. Recommendations are made for additional studies to fully utilize the properties of high-strength concrete.
