Compatibility of cement and pfa with plasticizer was studied through the slumptest of concrete from the aspects of cement, pfa and plasticizer.
通过混凝土坍落度试验，从水泥、粉煤灰及塑化剂三方面研究了水泥及粉煤灰与塑化剂的适应性问题。

The equivalent discrete element model of the conditioned sands is provided, on the basis of which the DEM numerical model of the slumptest and the shear test of the conditioned sands are established.
提出了改性砂土的等效离散元模型，在此基础上建立改性砂土坍落度实验和直剪实验的离散元数值实验模型。
