Abstract

The invention discloses a preparation method of an autoclaved aerated concrete block. The preparation method comprises the following steps: S1, preparing an additive A from aluminum powder paste, sodium sulfate and sodium abietate; and preparing fly ash, bagasse, juncus roemerianus powder, lime powder, gypsum powder and the additive A into ball billets, and curing to obtain lightweight aggregate; s2,preparing fly ash, ceramic tile waste, glass waste, quicklime and gypsum powder into a mixture; s3, preparing sodium hydroxide, rosin powder, triethanolamine and sodium silicate into an additive B; and S4, preparing a brick blank from the lightweight aggregate, the mixture, cement and the additive B, and maintaining the brick blank to obtain the autoclaved aerated concrete block. The invention further discloses the autoclaved aerated concrete block which is prepared by the preparation method of the autoclaved aerated concrete block. According to the autoclaved aerated concrete block, the construction waste, the household waste and the industrial waste are reasonably utilized, waste is turned into wealth, resource waste and environmental pollution are reduced, and the autoclaved aerated concrete block which is high in compressive strength and breaking strength and light in weight is prepared.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a method for preparing an autoclaved aerated concrete block and an autoclaved aerated concrete block. Background technique [0002] my country is a big country in the production of architectural ceramics. The annual production of ceramic tiles is about 3 billion square meters, with a mass of 20-24 kilograms per square meter, and about 60-72 million tons of raw material consumption per year. The fuel consumption per square meter is about 1.4-1.5 liters, and the annual fuel consumption is 420-450 million liters. It can be seen that the energy consumption in the production process of traditional architectural ceramics is very huge, and the ceramic tile production process needs to be fired at a high temperature of 1100-1220 ° C, and a large amount of waste gas CO is also emitted during the firing process. 2 , CO 2 It intensifies the greenhouse effe...
