Lastly, the values of long-term dry shrinkage of crushed sand concrete were observed and predicted by using RBF neural network model.
最后，用R BF神经网络模型预测了石屑混凝土的长期干缩值。
The freeze-resistance of crushed stone dust concrete was better than natural sand concrete. The impermeability of crushed stone dust and natural sand concrete is nearly.
石屑混凝土的抗冻性较天然河砂混凝土要好，抗渗性与天然河砂混凝土相当。
