Abstract

The invention discloses an environment-friendly low-cost building block and a preparation method thereof, belonging to the technical field of building material preparation. The environmentally friendly low-cost building block contains the following components in parts by weight: 45-55 parts of desulfurized magnesium oxide; 12-27 parts of magnesium chloride; 0.8-1.2 parts of aluminum ammonium sulfate; 0.05-0.5 parts of 24-88 polyvinyl alcohol ; and 90-110 parts of base material. Wherein, the base material is one or more of water slag powder, fly ash or ore washing slag ash. Meanwhile, the present invention also provides a method for preparing building blocks. The base materials used in the building blocks are industrial waste residues generated by mines or steel mills, and the cost of raw materials for the building blocks is close to zero. The formula composition of building blocks is improved, quicklime, gypsum, cement and other components are omitted, and desulfurized magnesium oxide and magnesium chloride are used as the main binders. The combination of base materials such as slag ash can form building blocks with high waterproof and fireproof performance and high strength in a short time.

Description

technical field [0001] The invention relates to an environment-friendly low-cost building block and a preparation method thereof, belonging to the technical field of building material preparation. Background technique [0002] A building block is one of the structural units that make up a building. There are many forms of existing building blocks, the most common being the traditional fire-fired brick blocks. This kind of building blocks generally requires excavation of specific soil, which greatly destroys land resources. At the same time, due to the need for firing, on the one hand, a large amount of resources will be wasted, and on the other hand, the environment will be polluted. At the same time, because the internal and external structures of fired brick building blocks are the same, the external surface is often rough and the surface strength is limited. Therefore, such building blocks have been gradually replaced by existing new building blocks. [0003] At presen...
