| Abstract: |
| 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-cas... |
| Key words: recycled aggregate precast concrete product strength durability |
