摘要
本文主要研究的是模袋混凝土冻融循环试验下宏观力学特性。通过对不同配合比下做出的模袋混凝土试块,在养护室内养护28天后,放进混凝土快速冻融试验机内,每循环25次测量试块的质量损失率和相对动弹性模量,分析研究模袋混凝土抗冻性及宏观力学特性。
This paper mainly studies the macroscopic mechanical properties of molded bag concrete under freeze-thaw cycles. After the molded bag concrete test block made under different mixing ratios was cured in the curing room for 28 days, it was placed in the concrete rapid freeze-thaw test machine, and the mass loss rate and relative dynamic elastic modulus of the test block were measured 25 times per cycle,to analyze the frost resistance and macroscopic mechanical properties of the molded bag concrete.
