| Abstract: | The mixed medium sand concrete is prepared using nature ultrafine sand and machine crushed limestone sand.Under the same mix ratio,the performance such as working performance,compressive strength,shrinkage and creep is compared with the concrete with nature river sand(medium sand) in this paper.The application of mixed sand concrete in the third Peijiang Bridge is successful. |
| Keywords: | mixed medium sand nature medium sand mixed ratio performance Application |
