The iron tailings were mixed in various proportions with different combinations of cement, sand, and sodium silicate to obtain or value-added product out of iron tailing waste which is suitable for use in the construction industry. Bricks were made using a variety of compositions of iron tailings, Ordinary Portland Cement, sodium silicate, and sand in cuboid mould (9″X 5″X 3″). The bricks were dried for 24 hours, and then kilned at 115 ± 10°C for 24 hours. Mechanical features such as water absorption, compressive strength, and efflorescence are tested. The maximum compressive strength rating of 8.58 N/mm² was recorded with ratios of 8:2 (Iron tailing and cement). However, in process of making it economical, the ratio of 9:1 has opted and this ratio complies with the requirement of the Indian standard (IS: 1077:1992) of the common burnt clay building bricks. Water absorption for the proposed bricks is less than that of burnt clay bricks. The lower capillary pore can prevent the formation of efflorescence. This process, with the same parameters, can be exchanged commercially, and a large number of wastes of iron ore can be used to make bricks. Therefore, the technological processes identified in this paper can convert large amounts of hazardous waste into the environment into value-added products. Iron tailing can be seen as a stable addition to clay soils, its use when restricted to making bricks. This research helps to open a new area of research.

印度卡纳塔克邦Donimalai矿山的铁矿石尾矿用于砖块制造

将铁尾矿以各种比例与水泥，沙子和硅酸钠的不同组合混合，以从铁尾矿废料中获得或增值产品，适用于建筑行业。在长方体模具（9“ X 5” X 3“）中，使用铁尾矿，普通波特兰水泥，硅酸钠和沙子的各种成分制成砖块。将砖干燥24小时，然后在115±10℃下煅烧24小时。测试了机械特性，例如吸水率，抗压强度和风化性。最大抗压强度为8.58 N / mm ²记录的比率为8：2（铁尾矿和水泥）。但是，在使其变得经济的过程中，选择了9：1的比例，该比例符合印度标准的标准（烧成粘土砖）的标准（IS：1077：1992）。所提出的砖的吸水率小于烧制的粘土砖。下部毛细孔可防止风化的形成。具有相同参数的此过程可以进行商业交换，并且可以使用大量的铁矿石废料来制造砖块。因此，本文确定的技术过程可以将大量危险废物转化为环境，转化为增值产品。铁尾矿可以看作是粘土的稳定添加物，仅在制造砖块时才可使用。这项研究有助于开辟一个新的研究领域。
