Embodiment 1
[0023] ① Mixing: Grinding the fly ash, high alumina slag, silicon powder, and clay until the average particle size is less than 400 μm, and then mixing the above raw materials with cement evenly to obtain a mixing material.
[0024] Raw material is made up of following components by weight part:
[0025]
[0026] ② Molding: After the mixture obtained in the mixing step is mixed evenly with water, the weight of water is 350, straw fiber and mullite fiber are added, the flat mold is vibrated, molded, and cured for 72 hours after demoulding.
[0027] The performance parameter of gained building brick is as follows:
[0028] .

Abstract
The invention relates to a building brick based on the utilization of fly ash and a natural material, and belongs to the field of building materials. The light building brick disclosed by the invention uses the fly ash, aluminous slag, silicon powder, clay, natural plant fiber and mullite fiber as raw materials, so that the obtained light brick has the advantages of low density and high strength; besides, the method eliminates the step of sintering, so that the production cost is greatly saved.
Description
technical field [0001] The invention relates to a building brick based on the use of fly ash and natural materials, belonging to the field of building materials. Background technique [0002] Building bricks are an indispensable basic building material for building materials. Lightweight bricks can reduce the load on the floor. The general lightweight bricks are prepared with sillimanite as the matrix, and special additives and a small amount of rare earth oxides are added. Refining, high pressure molding, high temperature firing. Ordinary lightweight heat-insulating refractory bricks are made of clay, high-alumina high-strength floating pearl bricks, low-iron mullite, high-alumina poly light-weight heat-insulating firebricks, and diatomite heat-insulating firebricks. However, the high-temperature sintering temperature is generally above 1000 degrees, and the preparation process consumes a lot of energy and is not environmentally friendly.
