Abstract

The invention discloses a non-autoclaved aerated brick which comprises the following components in parts by weight: 2200-2400 parts of fly ash, 1400-1700 parts of weathered sand, 1100-1200 parts of mineral tailing powder, 430-450 parts of ordinary cement, 220-240 parts of water and 43-45 parts of an additive, and further discloses a preparation method of the aerated brick, comprising the following steps: mixing the fly ash, the weathered sand and the mineral tailing powder and pulping; the slurry is pumped into a pouring machine, cement and various additives are added, waste is fully utilized, the environment is protected, high-temperature autoclaving is not needed, energy consumption is low, and the prepared aerated brick is high in strength and more stable in product performance.

Description

technical field [0001] The invention relates to the technical field of aerated bricks, in particular to a steam-free aerated brick and a preparation method thereof. Background technique [0002] Aerated bricks are flexible because of their hollow properties, which can leave a good expansion space for reinforced concrete structures. Aerated bricks have light weight, good thermal insulation performance, strong earthquake resistance, good processing performance, high temperature resistance, etc. It is a wall material that saves soil, utilizes waste, and saves energy, and has been widely used in building structures. [0003] At present, most of the traditional aerated bricks are sand aerated blocks and fly ash aerated blocks, which require high temperature for autoclaving, large investment, high energy consumption, and serious environmental pollution, which cannot meet the requirements of energy conservation and environmental protection.
