内外条件对混凝土拉仲徐变的影响

Effect of Internal and External Conditions on the Tensile Creep of Concrete

由于进行混凝土拉伸试验很困难。所以当前对于混凝土拉伸徐变的研究较少．本文收集了有关的试验资料，分析了影响拉伸徐变的几个重要因素，其中包括掺舍料、水灰比、湿度交换、加荷龄期等．总结了拉伸徐变的变化规律，其目的是让人们进一步了解混凝土的拉伸徐变及它对混凝土结构产生的影响．

The research on the tensile creep of concrete is made in this paper. Results indicate that mineral addictive, w/c ratio, drying conditions or sealed conditions and the age at loading have much influence on the tensile creep. The change law of the tensile creep is summed up. This article suggests that the influence of the creep on the construction be consid ered.
