Problems solved by technology

However, there are still many defects in the current foamed concrete. For example, concrete is a brittle material. During use, it is subjected to various physical, chemical or mechanical effects from the environment, which will cause its volume to deform. When the deformation exceeds a certain limit, it will eventually lead to cracking. destroy

Abstract

The invention provides radiation-resistant anti-cracking heat-insulating concrete, which comprises the following raw materials in parts by weight: 60 to 70 parts of cement, 3 to 6 parts of zirconium oxide, 3 to 6 parts of magnetite, 5 to 10 parts of inorganic fibers, 1 to 3 parts of a water-reducing agent, 35 to 45 parts of sand, 35 to 45 parts of coal ash, 7 to 10 parts of sodium dodecyl benzene sulfonate, 3 to 5 parts of bone glue, 5 to 10 parts of polyvinyl alcohol, 3 to 6 parts of silicon micropowder and 60 to 70 parts of water. The heat-insulating concrete provided by the invention guarantees excellent strength on the premise of reducing the cost, has excellent radiation resistance and toughness, overcomes the defects that the foam concrete has low toughness and low strength and is liable to crack in the prior art, and has heat-insulating and sound-insulating properties, impermeability, erosion resistance and other performance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a radiation-proof and crack-proof thermal insulation concrete. Background technique [0002] Foamed concrete is a kind of foaming agent that is fully foamed mechanically through the foaming system of the foaming machine, and the foam is evenly mixed with cement slurry, and then cast-in-place construction or mold molding is performed, and a large amount of concrete is formed through natural curing. A new type of lightweight thermal insulation material with closed pores; it has special properties such as thermal insulation, sound absorption and sound insulation, and lightweight porous, making it widely used not only in housing construction, but also in various industries such as roads, bridges, and tunnels. fields have been widely applied. However, there are still many defects in the current foamed concrete. For example, concrete is a brittle material. Durin...
