Problems solved by technology

The production of this brick not only requires a lot of arable land, but also releases a large amount of harmful gases during the firing process, such as carbon monoxide, carbon dioxide, hydrogen sulfide, etc., which pollute the environment and endanger human health.
Due to the single aggregate and insufficient fineness of raw materials in traditional river sand brick making, the gradation of raw materials cannot meet the requirements, resulting in low product strength and poor appearance

Abstract

The invention discloses a novel energy-saving and environment-friendly brick. The novel energy-saving and environment-friendly brick is prepared from raw materials in parts by weight as follows: 30-50parts of domestic sludge, 20-30 parts of shale, 18-27 parts of fly ash, 7-15 parts of quick lime, 10-20 parts of waste brick powder, 15-25 parts of ceramsite, 10-20 parts of attapulgite clay, 13-22 parts of cement, 5-10 parts of coal gangue, 3-9 parts of bauxite, 1-2 parts of a defoaming agent, 0.5-1 part of a water reducing agent, 0.7-1.2 parts of an early strength agent and 2-5 parts of biochar. The preparation method of the novel energy-saving and environment-friendly brick is simple, cost is low, and a prepared product is high in compressive strength, good in fracture resistance, excellent in performance and suitable for various places.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a novel energy-saving and environment-friendly brick and a preparation method thereof. Background technique [0002] At present, the load-bearing bricks for construction are still mainly clay bricks, and its main component is clay, which is formed by billet making and roasting. The production of this brick not only requires a lot of arable land, but also releases a large amount of harmful gases during the firing process, such as carbon monoxide, carbon dioxide, hydrogen sulfide, etc., which pollute the environment and endanger human health. Due to the single aggregate and insufficient fineness of raw materials in traditional river sand brick making, the gradation of raw materials cannot meet the requirements, resulting in low product strength and poor appearance. Contents of the invention [0003] The present invention provides a new type of energy-savin...
