| 摘要： | Very early strength (VES) concrete is one of three high performance concretes being examined by the Strategic Highway Research Program (SHRP). This report details the laboratory investigation of the mechanical behavior and field trials of high performance concrete for highway applications, and more specifically, VES concrete. The laboratory investigation consisted of tests for both the fresh or plastic concrete and the hardened concrete. Tests for the plastic concrete included slump, air content, unit weight, and concrete temperature. The laboratory tests for the hardened concrete included compression tests, tension tests, freezing-thawing tests, shrinkage tests, rapid chloride permeability tests, AC impedance tests, and tests for concrete-to-concrete bond. The results of the laboratory work indicated that VES concretes with enhanced frost resistance can be successfully produced in the laboratory and utilized in the field for highway pavements. |
