摘要
试验研究了常用混凝土材料拌制的混凝土的低温性能,包括低温强度性能、抗冻性能、热膨胀系数性能等。通过工程实例,介绍根据试验所得数据进行混凝土配合比优化,得出满足设计要求并且经济合理的混凝土配合比。
The low temperature performances of the concrete mixed by normal materials were studied in the experiment, including the cryogenic strength perform- ance, anti-frost performance and thermal expansion coefficient performance etc. Through a practical project example,it was introduced that the concrete proportio- ning was optimized according to the test data, and an economical and reasonable mix proportion of concrete which meets the design requirements was worked out.
