Lastly, the values of long-term dry shrinkage of crushedsand 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。

A part of fly ash might be replaced with stone powder in high-paste RCC, but the content of stone powder in crushedsand should be not more than 20%.
所以,在富胶凝材料碾压混凝土中可以用石粉取代部分粉煤灰,但人工砂中的石粉含量不宜超过20%。

Joint filling 48 hours after macadamize, use the mixture of cement and crushedsand with 1:0.5 to fill, after that, use the water to clean roughly the tile surface.
