再生骨料在混凝土预制件中应用的可行性研究

Feasibility Research on Recycled Aggregate Used in Pre-cast Concrete Component

研究了再生骨料的制备、组配以及再生骨料混凝土的抗冻、干燥收缩、抗碳化等性能,并对再生骨料混凝土预制构件进行了工程应用试验.结果表明,再生骨料混凝土在强度以及耐久性能方面与普通混凝土相对比几乎相同,完全能满足JASS 10规定的预制混凝土构件的质量标准,用再生骨料预制钢筋混凝土构件完全可行.

Pre-cast reinforced concrete component products with designed strength of 40 MPa were prepared with calcium containing expansive agent,blast furnace cement B and low absorption recycled aggregate as one of effective methods to use recycled aggregate.It is concluded that recycled concrete exhibits almost the same performance on strength and durability compared with common concrete,which meets all requirements set forth in standard of JASS 10,and it is feasible for recycled aggregate to be used in the pre-cast reinforced concrete product.
