再生混凝土的生产与应用

APPLICATION AND PRODUCTION OF RECYCLED COARSE AGGREGATE

介绍了再生骨料的制备技术,提出了再生骨料的生产工艺,对比研究了再生骨料的性能和再生混凝土的性能。采用先进工艺得到的高品质再生骨料完全可以满足《混凝土用再生粗骨料》(GB/T25177-2001)和《混凝土和砂浆用再生细骨料》(GB/T25176-2001)的要求,制备出满足结构工程需要的再生混凝土,并应用于工程中。

In this paper,the preparation technique of recycled aggregate is introduced,the production process of recycled aggregate is hereby proposed and the performance of recycled aggregate and recycled concrete are furthermore studied.By means of advanced process,high performance recycled aggregate satisfies the requirements from the code'Recycled coarse aggregate for concrete'(GB/T 25177-2001) and 'Recycled fine aggregate for concrete and mortar'(GB/T 25176-2001).Additionally,the corresponding recycled concrete has been applied in the construction and suffices for the structural engineering.
