Abstract

The invention discloses a kaolinite archaized brick and a preparation method thereof, and belongs to the technical field of restoration of ancient buildings. The kaolinite archaized brick is preparedfrom the following raw materials in parts by weight: 45-55 parts of kaolinite slag, 5-10 parts of coal gangue, 5-10 parts of corn straws, 5-10 parts of fine sand, 20-25 parts of sludge, 5-8 parts of salt gypsum, 5-8 parts of white cement, 0-2 parts of a silicon powder, 0.5-1.0 part of calcium chloride, 0.5-1.0 part of calcium oxide, and 0.5-1.0 part of EDTA disodium. The corn straw pulverized by apulverizer is added to the kaolinite slag and the coal gangue to increase the strength of the archaized brick, reduce the density of the archaized brick and reduce the weight; and the silicon powderadded not only improves the strength of the archaized bricks, but also causes the archaized brick to be blue gray with a vivid antique effect; and the sludge added reduces the cost of the archaized brick, and the sludge can be recycled to save natural resources such as sand and clay.

Description

Technical field [0001] The invention relates to the technical field of ancient building restoration, in particular to a kaolinite antique brick and a preparation method thereof. Background technique [0002] Kaolinite is also known as "kaolin" and "china clay". A clay mineral. It was named after it was first discovered in Gaoling Village near Jingdezhen, Jiangxi. Aluminosilicate minerals such as feldspar and pyroxene are formed during weathering. It is earthy or massive, with low hardness, plasticity, adhesion and volume expansion when wet, especially microcrystalline kaolinite (also known as "montmorillonite", "jiaolinite") has greater expansion (can be Up to several times to ten times). The main components of microcrystalline kaolinite and belayite are called bentonite. In addition to being used as ceramic raw materials, papermaking raw materials, rubber and plastic fillers, refractory materials, etc., kaolinite clay can also be used to synthesize zeolite molecular sieves ...
