| Abstract: | In this paper,waste concrete is crushed to produce recycled aggregate instead of coarse aggregate to prepare recycled concrete.Test results show that the concrete prepared with recycled waste,workability of which meets the construction requirements,strength and durability of which meet the engineering needs,has such characteristics as low density,low brittleness,crack resistance and good thermal insulation.Application-benefit analysis shows that the use of recycled concrete instead of concrete with low or m... |
