Abstract

The invention discloses an archaized brick prepared by using montmorillonite and illite and a preparing method thereof and belongs to the technical field of ancient building restoration. The archaizedbrick prepared by using the montmorillonite and the illite is prepared by the following raw materials in parts by weight: 15-25 parts of montmorillonite, 15-25 parts of illite, 5-10 parts of chlorite, 15-25 sludge, 5-10 parts of salt gypsum, 5-10 parts of white cement, 3-5 parts of modified vegetable fibre, 0-1 part of iron black, 0.5-1.0 parts of EDTA disodium, 0.5-1.5 parts of calcium hydroxideand 0.5-1.5 parts of sodium hexametaphosphate. The archaized brick prepared by using the montmorillonite and the illite, disclosed by the invention, has the advantage that a problem that cracks are easy to generate on a montmorillonite sintered brick is avoided by using the montmorillonite and the illite as main raw materials and using a pressing method to prepare the archaized brick. The archaized brick prepared by using the method disclosed by the invention has the advantages that the compressive strength is good, the freezing resistance is good, GB / T82392014 standard requirements are satisfied, the color of a brick body is a caesious color, the color is more vivid, and the archaized 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 by utilizing montmorillonite and illite and a method thereof. Background technique [0002] Exterior wall bricks are traditionally fired bricks. In the firing process, clay is mainly used as raw material. After the blank is formed, it is fired in a kiln to make green bricks or blue tiles. For excessive use of clay, the government has taken relevant compulsory measures to prohibit the use of clay as a raw material. Raw materials are used to produce building materials, and the traditional process of firing green bricks or green tiles takes a long period and high cost. [0003] At present, there are many reports on the use of montmorillonite to prepare sintered bricks, but montmorillonite minerals are one of the minerals that have the greatest impact on the processing and product performance of sintered bricks and tiles. Although m...
