Abstract

The invention belongs to the technical field of aerated block production, and especially relates to tailing slag aerated blocks, and a production method thereof. The production method comprises stepsof raw material treatment and blending, aging treatment, rolling treatment, standing treatment, and autoclave curing treatment. The appearance of the tailing slag aerated blocks is excellent; no surface crack is caused; size standard is reached, the durability is excellent; the compressive strength and the rupture strength are capable of satisfying building requirements; full utilization of tailing slag is realized; and the production method is green, and is friendly to the environment.

Description

technical field [0001] The invention relates to the technical field of aerated bricks, in particular to a tailings slag aerated brick and a production process thereof. Background technique [0002] Traditional solid clay bricks are heavy, which not only wastes national clay resources and high prices, but also cannot meet the requirements of some special building bricks. Therefore, many advanced areas have completely banned the use of red bricks, and instead strongly advocated aerated bricks. Compared with traditional clay bricks and ordinary concrete bricks, aerated bricks are not only light in weight, but also have the advantages of thermal insulation, excellent sound insulation performance, strong earthquake resistance, good processing performance, good high temperature resistance, and strong adaptability. However, the current production technology of aerated bricks is not mature enough, which makes the development of aerated bricks technology slow and unable to meet the n...
