Description
技术领域technical field
本发明涉及一种以裂隙粘土为主要原料的免烧砖及其制备方法，属于建筑材料技术领域。The invention relates to a non-burning brick with fissured clay as the main raw material and a preparation method thereof, belonging to the technical field of building materials.
背景技术Background technique
裂隙粘土是裂隙很发育的一种特殊粘土，其广泛分布于河南南部和西部，尤其在山区和丘陵垄岗地区分布广泛。裂隙粘土中含有较多的黏粒，矿物成分以伊利石、石英为主，并含有蒙脱石，化学成分以硅、铝、铁为主。裂隙粘土在天然条件下一般处于坚硬或硬塑状态，其密度较大，含水量小，粘粒含量较高，胶结较好，因此具有较高的强度和较低的压缩性。裂隙粘土具有一般粘土没有的特殊结构—裂隙结构，其地质特性也不同于一般粘土，如吸水时会膨胀软化，使土体结构破坏以致崩裂，严重影响强度，因此其特殊的性质大大制约了其在建筑工程上的应用。Fractured clay is a special clay with well developed fissures. It is widely distributed in southern and western Henan, especially in mountainous areas and hilly ridge areas. Fractured clay contains a lot of clay, the mineral components are mainly illite and quartz, and also contains montmorillonite, and the chemical components are mainly silicon, aluminum and iron. Fractured clay is generally in a hard or hard plastic state under natural conditions, with high density, low water content, high clay content, and good cementation, so it has high strength and low compressibility. Fractured clay has a special structure that ordinary clay does not have—crack structure, and its geological properties are also different from ordinary clays. Application in construction engineering.
免烧砖又称非烧结砖或新型墙砖，因其具有密实度大、吸水性好、耐久性好、强度较高等优点，且与烧结砖相当的产品质量和综合性能，已经成为烧结砖的新型替代材料。与烧结砖相比，免烧砖还具有以下优势：(1)节约土地资源，废物利用。免烧砖大多以工业废渣为原料，无需使用好土，可以保护耕地，同时能够大大利用工业废渣。(2)节约能耗，保护环境。免烧砖不需烧结和蒸养，大大降低了烧结砖生产过程中燃煤的使用，具有良好的社会和经济效益。(3)工艺简单、节约人力物力，降低生产成本。Unburned bricks, also known as non-sintered bricks or new wall bricks, have become the most popular sintered bricks because of their advantages of high density, good water absorption, good durability, high strength, and the same product quality and comprehensive performance as sintered bricks. New alternative materials. Compared with sintered bricks, unburned bricks also have the following advantages: (1) Save land resources and utilize waste. Most of the non-burning bricks are made of industrial waste residues as raw materials, which do not require the use of good soil, which can protect cultivated land and make great use of industrial waste residues. (2) Save energy and protect the environment. Non-burning bricks do not need sintering and steam curing, which greatly reduces the use of coal in the production process of sintered bricks, and has good social and economic benefits. (3) The process is simple, saving manpower and material resources, and reducing production costs.
