Machine-made sand tailing ground fine powder concrete mix proportion design method
The invention discloses a machine-made sand tailing ground powder concrete mix proportion design method, which comprises: S1, determining the initial proportion of cement and machine-made sand tailing ground powder in the concrete mix proportion, adding water, and mixing with the cement and the machine-made sand tailing ground powder to obtain a mixture; s2, filling the standard test container; s3, calculating the stacking compactness of the mixture; s4, the amount of the added water is gradually reduced, the steps S1 to S3 are repeated, and the closest packing density of the initial proportion of the cement and the machine-made sand tailing ground powder is obtained; and S5, changing the proportion of the machine-made sand tailing ground powder, repeating the steps S1 to S4 to obtain the tightest packing compactness of different proportions of the cement and the machine-made sand tailing ground powder, and determining the mixing amount ratio of the machine-made sand tailing ground powder in the cement. According to the method, the filling effect of the machine-made sand tailing ground powder in a concrete gel system can be fully considered, and the mixing amount range of the machine-made sand tailing ground powder in concrete can be more accurately controlled.
本发明公开了一种机制砂尾料磨细粉混凝土配合比设计方法，机制砂尾料磨细粉掺量的设计方法包括：S1，确定混凝土配合比中水泥和机制砂尾料磨细粉的初始比例，加入水与水泥、机制砂尾料磨细粉混合，得到混合料；S2，填满标准测试容器；S3，计算混合料的堆积密实度；S4，逐渐降低加入水的量，重复S1～S3，得出水泥与机制砂尾料磨细粉初始比例的最紧密堆积密度；S5，改变机制砂尾料磨细粉的比例，重复S1～S4，得出不同水泥与机制砂尾料磨细粉比例的最紧堆积密实度，确定机制砂尾料磨细粉在水泥中的掺量比。该方法能够充分考虑机制砂尾料磨细粉在混凝土胶凝体系中所起到的填充作用，更加精确的把控机制砂尾料磨细粉在混凝土中的掺量范围。
