A phase-change roof self-insulating ceramsite concrete

Abstract

The invention relates to phase-change roof self-insulation ceramsite concrete, and belongs to the technical field of building materials. The problems that existing ceramsite concrete is low in strength property and poor in energy storage effect can be solved. The phase-change roof self-insulation ceramsite concrete comprises, by mass, 30%-40% of cement, 20%-35% of pottery sand, 8.0%-13% of phase-change material, 10%-20% of ceramsite and 5.0%-8.0% of coal ash. The phase-change material uses the ceramsite as a loaded carrier. According to the concrete, the phase-change material is added and loaded onto the ceramsite, hence, a good energy storage effect can be achieved, and a large amount of heat can be stored or released when phase change happens; the phase-change latent heat range is wide, indoor temperature fluctuation is reduced, and cost is lowered; meanwhile, the strength property of the concrete can be guaranteed.

Description

technical field

[0001] The invention relates to a phase-change roof self-insulating ceramsite concrete, which belongs to the technical field of building materials. Background technique

[0002] With the development of the economy and the improvement of people's living standards, people have higher and higher requirements for the indoor comfort of buildings, and the problem of energy saving in buildings has become increasingly prominent. The active development of new energy-saving wall materials not only meets the needs of building energy conservation, but also meets the requirements of the national wall material innovation policy. In recent years, various places have done a lot of work in this area, among which the rapidly developed ceramsite and ceramsite concrete are an important aspect. Artificial ceramsite raw materials come from a wide range of sources, and ceramsite concrete has light weight, high strength, thermal insulation, and durability. , earthquake resistance a...
