| 摘 要： | 研究了湿排低钙粉煤灰的含水量、水泥用量与水泥稳定低钙灰作半刚性基层材料的强度之间的关系,设计了强度预测方法。该方法在考虑了室内与现场试验原材料含水量差异的基础上,通过给定水泥用量、实测压实混合料含水量和干密度,能够准确迅速地预测出压实混合料的强度。

| Abstract: | The relationships between water content of wet low-calcium fly ash and cement content and strength of cement stabilized fly ash used as semi-rigid base course materials are investigated,the prediction method is also designed.On the basis of water content difference from laboratory.and in situ raw materials,through cement contents are given,water content and dry density of compacted mixtures are measured.In situ,compaction strength of mixtures could be predicted accurately and quickly. |

| Keywords: | fly ash cement water content compaction strength prediction |
