正交试验分析不同配合比对高流态粉煤灰路基抗压强度的影响

Orthogonal Test Analysis of Impact on Different Mix of Compressive Strength of High Flowing Fly Ash Embankment

通过正交试验方案对水泥、外加剂、水、粉煤灰不同配比的抗压强度进行对比试验。针对遵义至毕节山区高速公路,提出水泥、外加剂对高流态粉煤灰抗压强度的影响,可为设计适应高流态粉煤灰的高强度、凝结时间少的路基提供参考和借鉴。

The compressive strength of cement, additives, water and fly ash with different ratio are compared through orthogonal test. In allusion to Zunyi-Bijie Expressway, the impact of cement and admixtures on the com- pressive strength of high-flow fly ash is put forward. It can provide reference for the design of embankment which can adapt the high strength of high flowing fly ash and condense with less time.
