Abstract

The invention discloses an archaized brick prepared by using red mud slag and a method thereof, and belongs to the technical field of ancient building restoration. The archaized brick is prepared fromthe following raw materials in parts by weight: 45-60 parts of red mud slag, 3-5 parts of water glass, 15-25 parts of sludge, 3-5 parts of salt gypsum, 3-5 parts of white cement, 2-4 parts of siliconpowder, 0.5-1.0 part of EDTA (ethylene diamine tetraacetic acid) disodium, 0.5-1.0 part of sodium sulfate and 1.5-2.5 parts of potassium chloride. According to the archaized brick prepared by using the red mud slag and the method thereof, the industrial waste of red mud slag serves as a main raw material, the white cement and the salt gypsum are added, the three excitation effects of chlorine salt excitation, sulfate excitation and alkali excitation are provided, so that the cementitious activity of the red mud slag is improved, and the water glass and the silicon powder are added, so that the cementitious activity of the red mud slag is further improved. The archaized brick has good compressive strength and frost resistance, meets the standard requirements of GB / T8239-2014, the color ofa brick body is reddish brown and is more vivid, and the archaizing effect is natural.

Description

technical field [0001] The invention relates to the technical field of restoration of ancient buildings, in particular to an antique brick prepared from red mud slag and a method thereof. Background technique [0002] Red mud slag is the residue left after iron or non-ferrous metals are extracted from red mud. With the development of my country's alumina industry, my country's red mud discharge has reached 73 million tons in 2013. The open-air stacking of red mud has caused serious environmental problems such as soil degradation, heavy metal pollution in the water environment, and air pollution. The recycling of red mud mainly includes two aspects, one is to recover valuable metals such as iron and aluminum in red mud, and the other is to directly use it as a raw material for building materials. At present, the red mud reuse rate in our country is only 4%, and there is an urgent need for a recycling method that can consume a large amount of red mud. [0003] At present, m...
