再生混凝土的性能研究

On performance of recycled concrete

为节能环保,将废弃的混凝土块加工制造粗骨料代替天然的砂石骨料,制造成再生骨料混凝土,从坍落度、弹性模量、强度、抗冻性、抗碳化性五方面,介绍了再生混凝土的性能,指出再生混凝土和普通混凝土性能相似,其用于城市建设中减少了对砂石资源的开发浪费。

In order to enhance the energy-saving and environment protection, the paper processes the wasted concrete blocks to produce the coarse aggregate to replace the natural gravel aggregate, makes the recycled aggregate concrete, introduces the recycled concreteJ s performance from the col lapsibility, elastic modulus, strength, freezing resistance and carbonation resistance, and points out the recycled and common con-cretes can be adopted in the urban construction, so as to reduce the development and waste of the grave resources.
