Abstract

The invention discloses an autoclaved aerated concrete block and a production process thereof. The raw materials comprise the following components in percentage by weight: 25-40% of cementing materials, 5-95% of slurry, 1.5-3.5% of gypsum and the balance gas generating agents, wherein the cementing material is one or a combination of more of fly ash, sand or silicon-containing tailings; the slurryis prepared by adding water into lime and cement, stirring and mixing; and the gas generating agent uses aluminum powder; the production process specifically comprises the following steps: S1, preparation of stone powder, S2, preparation of mixed ash, S3, batching, pouring and standing, S4, turnover cutting, S5, autoclaved curing, S6, finished product classification and finished product packaging, and S7, finished product inspection, classification and warehousing. According to the autoclaved aerated concrete block and the production process thereof, the autoclaved aerated concrete block hasthe characteristics of energy conservation, waste utilization, environmental protection, heat insulation, heat preservation, fire resistance, sound insulation and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an autoclaved aerated concrete block and a production process thereof. Background technique [0002] Autoclaved aerated concrete blocks are made by adding aluminum powder to the ingredients of calcareous and siliceous materials as an air-entraining agent, adding water to stir, pouring into shape, gas expansion, pre-curing and cutting, and then cured by high-pressure steam Porous silicate block, autoclaved air-entrained concrete block The air-generating agent, also known as the air-entraining agent, is the key material for the manufacture of air-entrained concrete. Most of the air-entraining agent is degreased aluminum powder. The aluminum powder mixed into the slurry produces a chemical reaction under alkaline conditions: the aluminum powder is extremely fine, and the hydrogen generated forms many small bubbles, which remain in the rapidly solidified concrete. These a...
