Abstract

The invention relates to a building material and a preparation process thereof, and in particular relates to a heat insulation brick containing ceramsites and a preparation method thereof. The technical scheme of the invention is as follows: a ceramsite heat insulation brick is provided. The ceramsite heat insulation brick comprises the following raw material in parts by weight: 20-40 parts of ceramsite, 20-40 parts of steel furnace slag, 5-10 parts of fluorite tailings, 8-9 parts of coal ash, 5-10 parts of white mud and 1-3 parts of activating agent. The ceramsite heat insulation brick has the beneficial effects that 1, if the brick disclosed by the invention is used in a building to build a wall body, the self-weight of the building is reduced by about 30% as compared with the traditional clay brick, basic building cost of a foundation is reduced, and project cost is reduced; 2, compression strength is high; 3, heat insulation, heat isolation and sound isolation properties are good;4, the brick has fire-resistant and seismic performance and is good in durability; and 5, the brick does not crack and is good in frost resisting property. The heat insulation brick is strong in practicability when in use; and because the heat insulation brick is light and high in strength, construction efficiency is high, and the heat insulation brick is suitable for various building structures.

Description

Technical field [0001] The invention relates to a building material and its manufacturing process, in particular to a thermal insulation brick containing ceramsite and a preparation method thereof. Background technique [0002] Although ordinary red bricks made with clay ingredients, embryos, and roasting can be used for load-bearing walls, they are already forbidden and have poor thermal insulation performance and do not meet energy-saving requirements. Common and lightweight concrete hollow blocks have been widely used. Among them, ordinary concrete hollow blocks are mainly made of coarse aggregates such as pebbles and crushed stones, engineering sand as fine aggregates, and ordinary Portland cement as binders, mixed with water, and formed by vibration molding and curing. Its apparent density is still large, and its thermal insulation performance is poor, and it cannot effectively replace ordinary red bricks. [0003] Ordinary light concrete hollow blocks are mostly made of coa...
