| Abstract: | According to the basic mixing principle and design key point of manufactured sand high performance concrete,the article determines the optimum mix ratio design plan by comparison analyzing the influence of different water to binder ratio and sand aggregate ratio on the performance.Combined with a T-pile construction practice of one bridge,the article also discusses the construction technique and quality control method of this concrete,and performs quality test on the construction of T-pile.The test result shows that all the tech-nique indexes meet the standard requirements and there is no appearance quality problem. |
