摘要: 在住建部"十三五"规划关于加强再生建材生产技术和工艺研发政策的指导下,文中提出了将再生骨料运用到清水混凝土工程中的建议,对再生骨料清水混凝土的制备工艺进行了设计,通过试验分析不同体积率的抗裂纤维掺入对再生骨料清水混凝土性能指标的影响,给出了掺入纤维的体积率建议;针对实际工程中再生骨料清水混凝土的质量缺欠,从模板工程、表面颜色差异和表面气孔等方面,分析了缺欠产生的原因,提出了施工工艺的优化建议。

Abstract: Under the guidance of the policy about strengthening the production and development technology of recycled materials in the“13th Five-Year”plan of the Ministry of Housing,the proposal of applying recycled aggregate to the project of fair-faced concrete is put forward in this paper.The preparation process of recycled aggregate concrete is designed and the effect on the performance index of recycled aggregate concrete with different volume rates of anti cracking fiber is analyzed by the experiment,so as to give the suggestion of volume rates of fiber.In view of the lack of quality of recycled aggregate concrete in actual engineering,the deficiency is analyzed from the aspects of template engineering,surface color difference and surface porosity.The reasons and optimization suggestions to the deficiency are put forward.

Key words: recycled concrete, fair-faced concrete, anti cracking fiber, construction technology
