Abstract

The invention relates to an autoclaved aerated concrete block prepared from natural granite chips and a preparation method of the autoclaved aerated concrete block. The blank of the autoclaved aerated concrete block comprises the following basic material components: 2450-3500kg of granite, 480-700kg of cement, 420-620kg of quick lime, 30-120kg of slaked lime, 42-150kg of flue gas desulfurization gypsum, 37-50kg of magnesia, 1.5-2.5kg of aluminite powder and 0.05-0.1kg of a foam stabilizer. The natural granite chips replace ordinary natural sand to serve as silica raw materials so as to prepare the autoclaved aerated concrete (AAC) block, so that the requirements on novel building materials are met, and a certain effects of regulating river and sand, protecting the environment and protecting ecology are achieved.

Description

technical field [0001] The invention belongs to the technical field of building wall materials, and in particular relates to an autoclaved aerated concrete (AAC) block prepared by using natural granite chips and a preparation method thereof. Background technique [0002] With the in-depth implementation of building energy-saving policies, autoclaved aerated concrete has increasingly become the first choice for building wall filling materials due to its unique properties such as light weight, high strength, thermal insulation, and fire resistance. Since the first autoclaved aerated concrete plant was built in the 1960s, after more than 40 years of development, China has now become the country with the most extensive application and the most mature technology. Compared with traditional bricks, [0003] Autoclaved aerated concrete (AAC) blocks have greatly improved the speed and quality of construction. In developed countries such as the United States, Japan, and Europe, auto...
