Abstract

The invention discloses a refractory insulating brick with a solid waste concave-convex core column. According to the weight sum of raw materials, the refractory insulating brick comprises: 70-80wt% of main materials and the balance of auxiliary materials, wherein the main materials comprise magnesium oxide containing solid wastes, and the auxiliary materials comprise aggregates, cement, gypsum and water. The auxiliary materials can also comprise an additive frequently used in the field to improve the performance of a brick material. The moisture content of an insulating brick body is lower than 5%. The brick body is of a concave-convex embedded structure; two bosses at the obverse side of the brick body and a convex part at the side of the brick body are formed into a bulge connection structure; grooves in the back of the brick body and a concave part at the corresponding side of the brick body are formed into an embedded connection structure; a matching structure formed by the bosses at the obverse side and the grooves in the back is circular; the bosses can be embedded into the grooves; a matching structure formed by the concave part and the convex part which are located at the sides is trapezoidal; and the convex part can be embedded into the concave part.

Description

technical field [0001] The invention relates to a thermal insulation brick and a preparation method thereof, in particular to a concave-convex core column solid waste fireproof thermal insulation brick and a preparation method thereof. Background technique [0002] According to a survey in 2012, there are more than 20,000 tailings in my country, nearly 20 billion tons, and billions of tons of solid waste. Not only does it need to occupy a lot of land, but the solid waste is piled up in large quantities, polluting land, or cause disasters such as landslides and mudslides; in addition, the debris and tailings formed by the weathering of solid waste are either washed into the water by water, or penetrate into the groundwater after dissolution, or are blown into the atmosphere by the wind, polluting with water and air as the medium The environment will directly pollute the environment; therefore, the existence of solid waste not only threatens the safety of people's lives and prop...
