Abstract

The invention belongs to the technical field of energy-saving construction materials and provides a construction waste sintering-free brick and a preparation method thereof. The construction waste sintering-free brick comprises the following raw materials in parts by weight: 20-25 parts of basalt powder, 16-29 parts of glass powder, 25-46 parts of arsenic rock, 15-28 parts of construction wastes, 1-3 parts of activated clay waste residues, 5-11 parts of vermiculite, 9-14 parts of high-bauxite fine powder, 11-15 parts of cement, 1-6 parts of calcium oxide, 2-5 parts of a stabilizing agent and 1-2 parts of a gelatinizing agent. The invention aims to provide the construction waste sintering-free brick and the preparation method thereof; the construction waste sintering-free brick overcomes the defect that the strength, the thermal insulation, the energy conservation and other performances of an existing sintering-free brick cannot meet the demands on modern industrial development.

Description

technical field [0001] The invention belongs to the technical field of energy-saving building materials, in particular, a non-burning brick for construction waste and a preparation method thereof. Background technique [0002] A new type of wall material produced by high-temperature calcination is called unfired brick. This product complies with China's "protection [0003] Farmland, energy conservation, adapting measures to local conditions, and local materials" is the general policy for the development of building materials. With the continuous deepening of the reform and opening up policy, the continuous development of the market economy, and the rapid development of urban construction, various municipal projects, public facilities, high-rise buildings, and civil buildings , Housing projects will rise from the ground and will require a large number of new wall materials. However, the existing unburned bricks have properties such as strength, heat preservation, and energy...
