Problems solved by technology

[0003] Therefore, the addition and use of clay is abandoned in the prior art, but cement, slag waste, etc. are used for processing and preparation. , blue ash, iron oxide black, tea residue powder, silicon dioxide, silt, etc. are prepared as raw materials. The prepared blue brick has good mechanical quality and avoids the use of clay. However, it is found in actual use that this kind of process The strength and other qualities of the green bricks still need to be better enhanced and improved

Description

technical field [0001] The invention belongs to the technical field of blue brick processing and manufacturing, and in particular relates to a preparation method of high-strength blue bricks for repairing ancient buildings. Background technique [0002] In the traditional craft, blue bricks are fired from clay, which is blue-gray, giving people a sense of elegance, calmness, simplicity, and tranquility. In recent years, it has become one of the products highly recommended by designers. Due to the high firing temperature, it has a certain The degree of vitrification has the advantages of high flexural strength, wear resistance, acid and alkali resistance, and long life. The traditional firing process is as follows: the clay is molded and dried in the shade, and then fired in the earthen kiln, it needs to go through carburizing, color preservation and other processes before it can be cooled out of the kiln. The whole process lasts about two weeks, making The production effici...
