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 discloses radiation-proof anti-cracking heat-insulating concrete. The concrete comprises the following components in parts by weight: 70-100 parts of cement, 10-20 parts of zirconia, 4-12 parts of silica powder, 5-10 parts of sodium silicate, 10-20 parts of sodium fluosilicate, 10-20 parts of barite, 5-12 parts of carbon fiber, 4-12 parts of colemanite, 3-9 parts of TPU, 8-18 parts of Cyanolite honeycomb powder, 5-12 parts of polyethylene methyl ether methacrylate, and 3-9 parts of calcium lignosulphonate. A preparation method is simple, the prepared concrete has excellent radiation-proof, anti-cracking and heat-insulating performances, and overcomes the defects that the concrete in the prior art is poor in toughness, low in strength and easy to crack.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular 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. During use, it ...
