Les caractéristiques mécaniques et la microstructure du béton des granulats recyclés a hautes performances

Abstract : As various kinds of building which were constructed in the early days of our country's foundation in China are close to the service life, the concrete industry in China faces two major challenges: the first one is the resource crisis, the pouring of concrete need to use a large number of natural aggregate; the second one is the environmental crisis, the construction waste which is produced by abandoned concrete and scrapped structural concrete may not only takes up the valuable land but also causes environmental pollution. Currently the research and utilization of recycled concrete is very little in my country. In the view point of sustainable development, the recycled aggregate concrete which is made from recycled concrete aggregates of waste concrete, fly ash, granulated blast-furnace slag and so on can greatly resolve the problem of coordinated development between resource and environment. Therefore, this article is mainly based on experiment and research, and had studied the basic properties and micro structure of the high performance recycled aggregate concrete. The main content is as follows: 1, Study and know about the concept of double interface, use the electrical scanner to observe the morphology and the interfacial transition zone of the high-performance recycled aggregate concrete. 2, A serious experiments and researches about basic mechanical properties of the high-performance recycled aggregate concrete were carried out , the experiment result indicated that the cube compressive strength ,axial compressive strength ,tensile splitting strength of high-performance recycled aggregate concrete are little lower than those of high-performance natural aggregate concrete on the same strength.
