摘要

With rapid economic development in China, the frequency of that new buildings replace old buildings increases gradually in rural areas, which inevitably results in the emergence of a large amount of waste clay brick. The processing of construction waste takes up a lot of land resources and worsen the existing rural environmental pollution situation, using waste clay brick to prepare recycled coarse aggregate concrete not only can effectively eliminate construction waste and reduce the consumption of original coarse aggregate and thus the cost of buildings, but also solves a series of environmental problems-it conforms to the concept of "green building" and stands in line with the strategic objectives of sustainable development. This paper researched on the influence of recycled coarse aggregate gradation and water cement ratio to the strength of recycled concrete at first, then experimentally verified the application feasibility of recycled coarse aggregate self-compacting concrete.
