Foamed concrete plate and preparation method thereof

Abstract

The invention relates to a foamed concrete plate and a preparation method thereof. The foamed concrete plate is characterized by being composed of the following components: early strength sulfo-aluminate cement, fly ash (two grade or higher), a calcium stearate foam stabilizer, a melamine water reducer, polypropylene fiber, industrial magnesium chloride, aluminum chloride, hydrogen peroxide, and the balance being water. The total weight percentage of the components mentioned above is 100%. The cement foamed plate has the same service life as that of a building. The fireproof and thermal insulation level can reach A1 grade. Moreover, the foamed concrete plate has the advantages of high bonding strength, good weatherability, and low thermal conductive coefficient. The raw materials such as sulfo-aluminate cement and fly ash are environment-friendly materials. The foamed concrete plate is accord with the national industry policy, has a good development prospect, and can replace the conventional products. The foamed concrete plate can be applied to wall thermal insulation in civil or industrial buildings. The thickness of thermal insulation layers can be calculated according to the present design standards for energy efficiency of buildings or city building energy efficiency requirements through heat engineering calculation.

Description

technical field [0001] The invention relates to a foamed cement board and a preparation method thereof. Background technique [0002] In the current building structure, many large buildings are reinforced concrete structures, and the floor slabs are cast on site. In addition, there are also some small buildings that are constructed with cement slabs mounted on columns and beams. In any case, the current cement slabs are Solid, no insulation. In recent years, with the development of the economy, people have increased the urgency of cooling and heating in summer and winter, and the northern region needs boiler heating for more than half a year, which also causes coal-fired boilers to pollute the air, causing some large cities in the north Air pollution has greatly increased the heat preservation requirements for buildings here. At present, some heat preservation measures are limited to adding a heat preservation layer on the exterior, but the protection and heat preservation ...

In recent years, with the development of the economy, people have increased the urgency of cooling and heating in summer and winter, and the northern region needs boiler heating for more than half a year, which also causes coal-fired boilers to pollute the air, causing some large cities in the north Due to air pollution, the heat preservation requirements for buildings here are greatly increased. At present, some heat preservation measures are limited to adding a heat preservation layer on the outside, but the protection and heat preservation of the floor is not enough.
