Studying on the Recycled Concrete of Performance and Prospect

摘要

With the continuous deepening of environmental awareness, Re-use of building materials attracts great attention to our field. Through the analysis and research of a large number of domestic and foreign literature, this paper mainly focused on the four performance comparison and analysis which are Compression Strength Frost resistance Drying shrinkage, Impermeability and chloride ion permeability. From the comparison and analysis we can draw the conclusion of reliability on the economy and performance of recycled concrete. Thus, combining environmental protection and the sustainable development of the constructional industry, this paper puts forward that the technological development of recycled concrete topics still need further study. It also points out the development of recycled concrete application contribute a lot to the fundamental solution to the ecological environment caused by wasting of massive concrete, increasing shortage of natural aggregate. At the same time, it also shows that the prospects of recycled concrete development.
