| 摘要： | This report documents the laboratory investigations of the mechanical behavior and field trials of high performance concrete for highway applications. High early strength (HES) concrete is one of the three categories of high performance concrete examined by the Strategic Highway Research Program (SHRP). The objective of this particular investigation is to obtain information on the mechanical behavior of HES concrete and to demonstrate its use under field conditions. The laboratory investigation consisted of tests for both fresh or plastic concrete and hardened concrete. The plastic concrete tests included slump and air content. The hardened concrete tests included compression tests, tension tests freezing-thawing tests, shrinkage tests, rapid chloride permeability tests, AC impedance tests, concrete-to-concrete bond tests, and tests for bond between concrete and steel reinforcement. Field experiments were conducted in New York, North Carolina, Arkansas, Illinois, and Nebraska to simulate a variety of environmental and exposure conditions. Results of these investigations indicate that HES concretes with enhanced frost resistance can be successfully produced in the laboratory and used in the field for highway pavements. |
