Problems solved by technology

The reason is: theoretically, the amount of binder in the high fluidity slurry should not be too small, less than 450kg / m 3 When it is used, it is almost impossible to guarantee the quality of concrete molding, generally it should not be less than 500kg / m 3
In the preparation of lightweight ceramsite concrete floor, the bulk density generally required is 1000-1200kg / m 3 , the amount of cement material is generally 280-350kg / m 3 , increase the amount of cement, its density increases, and the thermal conductivity cannot meet the design requirements

Abstract

The invention particularly relates to a functionalized low-density ceramsite concrete ground material for heating. The material is prepared from, by mass, 25-35% of cement, 20-40% of ceramsite, 30-40% of ceramic sand, 4-15% of ceramsite calcination fly ash, 0.5-1.5% of carbon fibers, 0.01-0.1% of organic nano-micron microspheres, 0.1-1% of tourmaline, 0.1-1% of water reducer, 0.05-0.5% of a water-retaining agent and 0.1-1% of hydrogel. The material has the advantages of being good in application property, high in strength, low in density and capable of decomposing formaldehyde and enhancing floor heating thermal radiation.

Description

technical field [0001] The invention specifically relates to a functionalized low-density ceramsite concrete floor material for heating, which is mainly used as a new building material. Background technique [0002] In response to the challenges of global climate change, resource and energy shortages, and the deterioration of the ecological environment, human beings are following the concept of carbon cycle, oriented by low carbon, developing circular economy, building low-carbon ecological cities, and popularizing low-carbon green buildings. China's green buildings have entered the era of large-scale development. During the "Twelfth Five-Year Plan" period, it is planned to complete 1 billion square meters of new green buildings; by the end of 2015, 20% of new urban buildings will meet the requirements of green building standards. [0003] Building energy conservation is an important part of green buildings. With the implementation of energy conservation standards for low-en...
