Concrete Crack Resistance Research Based on Temperature Stress Test-A Short Review
摘要
Abstract
The working principle and development history of cracking frame and temperature stress testing machine were introduced. Some research work on the crack resistance of early age concretes based on thermal stress test during the past 40 years were reviewed. According to the previous studies in Nanjing Hydraulic Research Institute, the influence of aggregate types and temperature histories on the crack resistance by temperature stress testing machine were investigated. Some main aspects for thermal stress test that need to be further investigated were discussed, including standardization of testing machine and test method, controlling of restraint degree, measuring accuracy of Young's modulus, quantification of concrete cumulative damage induced by to-and-fro movements, and calcu-lation method of early age creep, et al.关键词
