Abstract

The invention relates to a light aggregate assembly type sheet material and a production technology thereof. The sheet material is prepared from the following raw materials in parts by weight: 200 to 400 parts of cement, 100 to 200 parts of water, 350 to 460 parts of ceramsite, 0.2 to 0.4 part of foaming agent, 0.1 to 0.4 part of porcelainizing agent, 0 to 0.2 part of thickening and water retaining agent, 0 to 2 parts of water reducer, and 0 to 2 parts of plasticizer. The preparation method comprises the following steps: preparing raw materials according to the formula mentioned above, evenly mixing water, cement, a thickening and water retaining agent, a water reducer, a plasticizer, and a porcelainizing agent to obtain slurry, adding a foaming agent into the slurry to carry out foaming, then adding ceramsite, evenly mixing, pouring the mixture into a mould, carrying out curing for 24 hours, cutting, and performing maintenance. The provided light aggregate assembly type sheet material has the advantages of little thermal conductivity, good thermal performance, good soundproof and thermal insulation effect, low water absorption, high compression strength, and large hanging force, meets the requirements on wall strength, and integrates the advantages of foam concrete and light aggregate.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a light aggregate assembled plate and a production process thereof. Background technique [0002] For traditional wall structures, for high-rise structures, internal partition walls are mainly aerated blocks, masonry, hollow bricks, self-insulating blocks, etc.; for multi-storey buildings, mainly cement bricks or hollow bricks, red bricks. These materials have many problems: (1) they need to be built one by one, which greatly reduces the efficiency of construction; (2) there are many joints in block materials, and the construction quality is not easy to guarantee, especially the flatness and verticality of the wall (3) Traditional block materials need to mix mortar on site, and the construction process is cumbersome; (4) The joints of block materials are mortar, which has poor integrity; (5) Traditional block materials have low strength and are generally us...
