Mine tailing brick for roads and preparation method thereof
The invention discloses a mine tailing brick for roads and a preparation method of the mine tailing brick. The mine tailing brick comprises tailing slag, medium sand, cement, water and additives. Thepreparation method comprises the following steps: S1, dry mixing; S2, wet mixing; and S3, pouring and molding. According to the preparation method, two times of processing molding are adopted throughdry method and wet method, so that the strength and moisture of the molded product are easy to control; the molded product is pressed in a molding cavity, so that brick preparation is more convenient,no firing is needed, no steaming is needed, energy is saved, no pollution is caused; in pressing, a vacuum mechanism is adopted for extracting air, on one hand, the downward pressure of a pressing plate can be larger, the reverse abutting force of air on the pressing plate is eliminated, and on the other hand, air holes in the brick can be eliminated, so that the strength of the brick is higher.
一种道路用矿山尾矿砖块及其制备方法，包括尾矿渣、中砂、水泥、水以及外加剂，S1、干式混合：S2、湿式混合：S3、浇筑成型：本发明通过干式法、湿式法两次加工出型料，使得型料的强度、湿度均易把控；型料在型腔内被压成型，可使得砖块的制备更为简便，不用火烧、不用蒸养，既节约能源，又无污染；在压制时，真空机构抽气，一方面可使得压板的下压力更大，消除空气对压板的反向抵触力，另一方面可消除砖块内有气孔，使得砖块的强度更高。
