摘要
比较分析现今混凝土早龄期拉伸徐变的测试方法,自行设计一套可用于测试混凝土早龄期拉伸徐变的框架系统,实现对混凝土早龄期拉伸徐变的定量评价。以水灰比为0.58的普通混凝土为研究对象,验证该试验方法的可靠性。试验结果表明:该试验系统可有效测试出混凝土早龄期拉伸徐变的大小,符合试验设计原理与目的。
The current test methods for the tensile creep of concrete at early age are studied. A test frame system is developed to examine the tensile creep of concrete at early age, which fulfills the quantitative evaluation on the tensile creep of concrete at early age. A series of tests are made on ordinary concrete with 0.58 W/C ratio to verify the reliability of the test method. The test resuhs demonstrate that the tensile creep of concrete at early age can be effectively obtained by the mentioned test method and that the principle and purpose of the test design can be satisfied.
