Abstract: To compound C50 in the constructiion of box-girder of the superstructure of Huanghuayuan bridge, medium sands made in Jianyuang are rreplaced by composite mortars made up of machine-processed sands and sands made in Quhe. The practical application and the analysis of experimental data sow that working behavior and mechanics performance of the composite mortars are basically similar to that of concrete compounded by the medium sands made in Jianyang. Besides, the application of the composite mortars has attained remarkable economic benefits. Thereby, the development, spread and application of this kind of technology in city of Chongqing will be certain to bring about tremendously great economic benefits.

Key words: machine-processed sands, C50, engineering practical summary
