高强度再生骨料和再生高性能混凝土试验研究

Experimental research on high strength recycled aggregate and recycled high performance concrete

本文作者认为对高强度再生骨料的研究将越来越重要。介绍了再生高性能混凝土的概念,通过试验研究了高强度再生骨料对混凝土基本性能的影响,成功地配制出坍落度为245mm、28天强度达54 9MPa的再生混凝土。特别地,应用全部再生骨料配制的混凝土的三年强度达到了96 1MPa。作者认为,再生高性能混凝土的开发有助于扩大再生混凝土的应用。

In this paper,the author consider that the research on High Strength Recycled Aggregate(HSRA) will be more and more important.The conception of Recycled High Performance Concrete(RHPC)has been introduced,the influence of HSRA on the basic properties of concrete has been studied by test and the RHPC with slump of 245mm?compressive strength of 549MPa for 28 days had been prepared successfully.Especially,the strength of the concrete prepared with entirely HSRA was up to 961MPa at 3 years.The author consider that the exploitage for RHPC is helpful in expanding the use of recyeled concrete.
