| Abstract: |
| Based on the research and the application analysis of the concrete aggregate gradation, we point out that we can apply the Talbol method to carry on the aggregate gradation analysis and optimization of mine coarse filling. And an analysis had carried on to the broken waste rock aggregate and the Gobi coarse sand's gradation of the JinChuan mining area. According to the intensity of the orthogonal test that: in the same condition of cement dosage and the weight concentration, the bigger the aggregate accumulation density is, the higher strength of test block is. And under the condition of same cement dosage, with the decrease of water cement ratio, the strength of test block increase observably. |
