Abstract

The invention relates to the technical field of building materials, and particularly provides a wallboard and a preparation method and application thereof. The wallboard comprises two side plates and a light concrete layer which is fixedly clamped between the two side plates. The light concrete layer is used as the middle layer, the two sides are used as the side plates, the brittleness of the side plates can be improved, and the tensile crack of the side plates caused by the stress generated by building settlement is improved. The light concrete layers of the two side plates and the middle layer can be used for manufacturing concrete prefabricated parts with composite requirements according to performance requirements and products with different densities. The invention provides a preparation method of a wallboard, which comprises the steps of casting light concrete slurry between two side plates, and curing to obtain a wall body.

Description

Wallboard and preparation method and application thereof
Technical Field
The invention relates to the technical field of building materials, in particular to a wallboard and a preparation method and application thereof.
Background
Along with the continuous development of national economy, civil houses, commercial house buildings and old city transformation, the used partition wall materials are mostly aerated concrete blocks, hollow bricks and calcium silicate board products, the density of the materials is high, the specific gravity is high, so that the bearing load of the building foundation is large, the strength of a bearing frame of the building is required to be improved, and the building construction cost is increased.
Therefore, some domestic enterprises have put forward to produce high-strength light porous partition wall plates to replace traditional concrete blocks, and construction and material costs are improved. The density of the light porous partition wall board is lower than that of the traditional building block, the light porous partition wall board is formed by firing at high temperature, and the light porous partition wall board has the advantages of heat preservation and insulation, fire prevention A1 grade, flame retardance and the like, but the brittleness is higher, the specification of the porous partition wall board is larger in practical application, and when a building is slightly settled, the wallboard is pulled to crack under the stress action. Therefore, the development of the wallboard which is light in weight, low in cost, good in toughness and convenient to assemble on site is of great significance.
In view of the above, the present invention is particularly proposed.
Disclosure of Invention
The invention aims to provide a wallboard, which is used for relieving the technical problems of overlarge weight, poor toughness and high manufacturing cost of the wallboard in the prior art.
The second purpose of the present invention is to provide a method for preparing a wallboard, so as to alleviate the technical problems of the prior art that the preparation method is too high in cost and complicated in process.
The third purpose of the invention is to provide the application of the wallboard in the building.
In order to achieve the above purpose of the present invention, the following technical solutions are adopted:
the invention provides a wallboard which comprises two side plates and a light concrete layer fixedly clamped between the two side plates.
Furthermore, one side end face of the light concrete layer protrudes out of the two side plates to form a tenon, and the other side end face of the light concrete layer is recessed into the two side plates to form a mortise matched with the tenon.
Further, the light concrete layer comprises the following raw materials in parts by weight: 500 portions of cement 400-plus, 330 portions of inorganic porous material particles passing through a plus 8 mesh sieve 270-plus, 480 portions of inorganic porous material particles passing through a minus 8 to a plus 16 mesh sieve 420-plus, 420 portions of inorganic porous material particles passing through a minus 16 mesh sieve 360-plus and an optional auxiliary agent;
preferably, the inorganic porous material particles are mainly derived from ceramic waste materials, including waste materials of foamed ceramics or foamed ceramic wallboards;
preferably, the auxiliary agent comprises at least one of 1-3 parts by weight of hydroxypropyl methyl cellulose, 0.1-1 part by weight of carboxymethyl starch ether and 5-15 parts by weight of heavy calcium;
