The Carbonized Life of Fiber Reinforced Concrete Nuclear Waste Storage Containers

Abstract:

The hybrid fiber reinforced concrete containers for keeping nuclear waste (NWSC) were made by the concrete which mixed polypropylene fibers (0.9kg/m3) and 20mm basalt fiber (2.5kg/m3). The carbonation depth model was established by analyzing carbonation depth of ordinary concrete and hybrid fiber reinforced concrete that through the accelerated carbonization testing. And then two kinds of different concrete NWSC carbonation life were predict according to the similarity theory. The results show that the carbonation life of hybrid fiber reinforced concrete NWSC is 67％ higher than ordinary concrete ones, The addition of fiber can improve the resistance ability of concrete. The hybrid fiber reinforced concrete storage container can meet the requirements of the service life-300a when the thickness of the protective layer is more than 32mm.
