| Abstract: | Based on mixing of the reactive powder concrete applied to the Canadian Sherbrook pedestrian bridge, 200 MPa reactive powder concrete made of Chinese materials is developed with the compressive strength of (168.6 MPa) and the flexural strength of 21.6 MPa. The concrete possesses excellent mechanical properties and durability. The pedestrian members of bridges made of the concrete have passed the expert appraise and will be applied to Qinghai-Tibet railway bridges. |
