In this embodiment, a foamed ceramic plate 130 and a middle layer 110 on both sides are respectively provided with a foamed ceramic particle concrete layer 150 therebetween. The material of intermediate level 110 is rock wool, and intermediate level 110 can be the rock wool board, and rock wool has excellent fire prevention heat preservation performance.
The foamed ceramic particle concrete layer 150 comprises the following raw materials in parts by weight: 500 portions of cement, 330 portions of ceramic particles passing through a plus 8 mesh sieve, 480 portions of ceramic particles passing through a minus 8 to a plus 16 mesh sieve, 420 portions of ceramic particles passing through a minus 16 mesh sieve and an auxiliary agent. In general, sand is used as the aggregate in the general concrete layer, and in this embodiment, ceramic particles passed through a +8 mesh sieve, ceramic particles passed through a-8 to +16 mesh sieve, and ceramic particles passed through a-16 mesh sieve are used as the aggregate in the foamed ceramic particle concrete layer 150 instead of sand. The concrete contains porous ceramic particles, so that the overall weight of the concrete can be effectively reduced, the concrete is much lighter than common concrete in specific gravity, the load is reduced, and the foamed ceramic particle concrete layer 150 has better specific gravity and mechanical properties. And since the foamed ceramic particle concrete layer 150 contains porous ceramic particles, the foamed ceramic particle concrete layer 150 has excellent heat preservation, heat insulation and sound insulation properties.
It should be noted that the mesh is often used as a unit of material particle size or mesh size. The larger the mesh number, the finer the particles, a quantifier commonly used in laboratory samples to break down particle size. Generally, the mesh number × pore size (micrometer number) is 15000. For those skilled in the art, a "- (negative sign)" is often added before the arabic numeral of the mesh number to indicate that the granule passes through the selected sieve, and a "+ (positive sign)" indicates that the granule fails to pass through the selected sieve. For example: "-80 mesh" means particles that pass through an 80 mesh screen; "+ 120 mesh" indicates particles that do not pass through a 120 mesh screen.
In the present application, the ceramic particles are made from waste material of foamed ceramics. The foamed ceramic waste is relatively common in the building industry and low in acquisition cost. The foamed ceramic waste is used as a main source of ceramic particles, so that on one hand, the burying treatment cost of the ceramic waste can be effectively saved, and the environmental burden is reduced; on the other hand, the ceramic waste is used for replacing natural resources such as sand stone and the like, so that the sand stone can be saved, and the pressure of shortage of concrete aggregate resources is relieved.

Hydroxypropyl methylcellulose and carboxymethyl starch ether play a role in water retention agent and retarder, prolong the operable time, have the function of adhesion enhancement, and can also reduce the cement consumption. The water retention of the hydroxypropyl methyl cellulose and the carboxymethyl starch ether ensures that the concrete is slowly solidified, and the strength after hardening is enhanced.
The redispersible emulsion powder is a water-soluble redispersible powder adhesive, and the powder can be quickly redispersed into emulsion after contacting with water, and has high binding capacity and unique performance. Besides endowing the mortar with excellent alkali resistance, improving the adhesive bonding property, the breaking strength, the waterproofness, the plasticity, the wear resistance and the workability of the mortar, the mortar has stronger flexibility in the flexible anti-crack mortar. Preferably, the redispersible latex powder comprises one or more of copolymer rubber powder of vinyl acetate and ethylene, ternary copolymer powder of ethylene, vinyl chloride and vinyl acetate laurate, ternary copolymer powder of vinyl acetate, ethylene and vinyl ester of higher fatty acid, vinyl acetate acid homopolymerization rubber powder and copolymer rubber powder of styrene and butadiene.
The defoaming agent comprises one or more of higher alcohol fatty acid ester compound, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropylene amine ether, polyoxypropylene glycerol ether, polyoxypropylene polyoxyethylene glycerol ether and polydimethylsiloxane. The performance of the lightweight concrete can be further adjusted and optimized by adjusting the compounding and the dosage of the auxiliary agent.

A gasket is provided between the head of the bolt 160 and the corresponding foamed ceramic plate 130 to increase the fastening force of the bolt 160. The rear end of the bolt 160 is fastened by tightening a nut, and a washer is disposed between the nut and the corresponding foamed ceramic plate 130 to increase the fastening force of the bolt 160. The gasket is a rubber gasket or a metal gasket.

In this embodiment, the tile glue 134 comprises the following raw materials in parts by weight: 30-40 parts of cement, 55-65 parts of inorganic porous material powder which is sieved by a minus 30-mesh sieve and 0.05-4 parts of auxiliary agent. The raw materials of the inorganic porous material powder comprise one or more of volcanic rock, light partition wall board waste residue or foamed ceramic insulation board waste residue. In the ceramic tile glue 134, the inorganic porous material powder replaces the traditional sand, so that the using amount of the sand is reduced, and meanwhile, the porous structure has a larger specific surface area, so that the density of the ceramic tile glue 134 is reduced, and the bearing capacity of a base body is further reduced. The particle size of the inorganic porous material powder is limited to be sieved by a minus 30-mesh sieve, so that the uniformity of the components of the ceramic tile adhesive 134 can be ensured, and the advantages of the inorganic porous material powder are not lost.
