摘要
根据加拿大舍布鲁克人行桥采用的活性粉末混凝土配制,研制了适合我国原材料的200MPa级活性粉末混凝土,抗压强度为168.6MPa,抗折强度为21.6MPa。该活性粉末混凝土具有优越的力学性能和耐久性能。由该材料制备的桥梁人行道构件已通过铁道部专家鉴定,拟用于青藏铁路桥梁的实际工程中。
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.
