Iron tailing unfired water permeable brick and preparation method thereof
The invention discloses an iron tailing unfired water permeable brick and a preparation method thereof. The iron tailing unfired water permeable brick is prepared from the following raw materials in parts by weight: 100-250 parts of cement, 400-600 parts of iron tailings, 200-300 parts of gravels, 40-100 parts of desulfurized fly ash and 100-120 parts of water. The process of the unfired water permeable brick is simple, the utilization rate of tailing solid waste is high, the problem that a large number of tailings are accumulated in a concentrating mill is solved, the water permeable brick for the ground surface can be provided for urban construction, and the prepared unfired water permeable brick is light in weight, good in strength, high in durability and abrasion resistance, good in crack resistance and toughness, low in cost, small in energy consumption and free of pollution to the environment.
本发明公开了一种铁尾矿免烧透水砖及其制备方法，由以下重量份数的原料制得：水泥100份～250份、铁尾矿400份～600份、碎石200份～300份、脱硫灰40份～100份和水100份～120份。本发明制行的免烧透水砖，工艺简单，对尾矿固体废弃物利用率高，既解决了选矿厂大量的尾矿堆积问题，又能为城市建设提供地表用透水砖，制备的免烧透水砖重量轻，强度好，耐久性和耐磨性强，抗裂性和韧性较好，成本低廉，对能源消耗小且对环境无污染。
