摘　　要：对比了塞尔维亚多瑙河大桥工程所用天然卵石集料与国内卵石集料的差异,并分别采用两种天然卵石集料配制C50梁混凝土。试验结果表明,采用两种天然卵石作为集料可分别配制出工作性能优良,力学性能和耐久性等性能均能满足设计要求的C50梁混凝土。Differences between domestic pebble aggregate and natural pebble aggregate adopted in Zemun-Borca Bridge are studied. Also, C50 beam concrete is prepared with both two kinds of pebble. Experimental results show that both two pebble aggregates can be adopted to prepare the required C50 beam concrete, which have excellent working performance, mechanical properties artd durability.
