Embodiment Construction

[0015] A kind of durable aerated brick, it is made by the raw material of following weight kg:

[0016] CFB desulfurization fly ash 17, soda ash 1, limestone powder 5, hollow glass microspheres 5, calcium sugar 1, cement 20, gypsum 19, hydrogen peroxide 15 with a concentration of 18%, alum 4, jade powder 2, sodium diacetate 2, Polypropylene fiber 2.8, calcium chloride 1, modified filler 32;

[0017] The modified filler is prepared from the following weight kg raw materials: silane coupling agent KH540 2, bamboo charcoal powder 1, potassium feldspar 15, carbide slag 28, rice husk charcoal 0.8, clay 1, kaolin 30, sebacic acid Dioctyl 0.5, tricresyl phosphate 2, calcium formate 2;

[0018] The preparation method of described modified filler is:

[0019] Take potassium feldspar and calcium carbide slag, mix them evenly, and crush them. The obtained powder is flash-fired in a flash-fired kiln at 900°C for 5 seconds, then taken out and cooled, and mixed with kaolin, dioctyl sebaca...

Abstract

The invention discloses a durable air-added brick. The durable air-added brick is prepared from the following raw materials in parts by weight: 10-20 parts of CFB desulfurized coal ash, 1-2 parts of sodium carbonate, 3-5 parts of limestone powder, 3-6 parts of hollow glass bead, 1-2 parts of sugar calcium, 20-30 parts of cement, 15-35 parts of gypsum, 8-15 parts of hydrogen peroxide with the concentration being 10-20%, 2-4 parts of alum, 1-2 parts of jade powder, 1-2 parts of sodium diacetate, 1.5-2.8 parts of polypropylene fiber, 1-2 parts of calcium chloride and 35-48 parts of modified filler. The durable air-added brick disclosed by the invention has the advantages that the firm and durable effects are achieved, simultaneously the volume weight is low and the service life is long.

Description

technical field [0001] The invention relates to the field of aerated bricks, in particular to a durable aerated brick. Background technique [0002] Aerated bricks refer to aerated concrete blocks produced by high-temperature autoclaved equipment.
