| Abstract: |
| Steel fiber concrete has found wide application because of its reduction of the stress concentration in tip of thin crevices resulted from loads in elementary concrete for the improvement of rupture. The subject that how to develop and apply the concrete has become one of researching objects with wide technology market. The present paper discusses in detail the work conducted in laboratory scale, and summaries the application effect by analyzing the practical engineering case. |
