Abstract

The present invention relates to an autoclaved aerated concrete plate produced by using Yellow River sand. The base material components of the concrete plate billet comprise 2450-3500 kg of Yellow River sand, 480-700 kg of cement, 420-620 kg of quick lime, 30-120 kg of slaked lime, 42-50 kg of desulfurized gypsum, 37-50 kg of magnesite, 4.0-4.5 kg of aluminum powder paste, and 0.05-0.1 kg of a foam stabilizer. According to the present invention, the Yellow River sand is adopted to replace the ordinary natural sand so as to be adopted as the siliceous material, and the prepared ALC plate has characteristics of high compressive strength, high stiffness, low deflection value, high bonding strength between the billet and the steel bar, good flatness, substantially-improved construction efficiency, project cost reduction, and broad market prospects.

Description

technical field [0001] The invention belongs to the technical field of building wall materials, and in particular relates to an autoclaved aerated concrete slab prepared by using sand from the Yellow River 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 my country built the first autoclaved aerated concrete plant in 1965, after more than 40 years of development, it has become the country with the most extensive application and the most mature technology. Compared with traditional bricks, aerated concrete blocks have greatly improved the construction speed and quality. In developed countries such as the United States, Japan, and Europe, aerated concrete panels, as a symbol of b...
