Cast-in-place lightweight wallboard and floor

Abstract

The invention discloses a cast-in-place lightweight wallboard and floor, and belongs to the field of a building material. The cast-in-place lightweight wallboard and floor comprises a plaster mortar board, a steel wire mesh and an inner mold, wherein the steel wire mesh is in a grid shape and comprises an upper layer and a lower layer; a W-shaped support steel wire is arranged between the layers;the inner mold is placed in grids of the two layers of steel wire meshes; the plaster mortar board is prepared from plaster power, pulverized fuel ash, waterproof agents, paper pulp, fiber, red mud, quartz powder, magnesium oxide, magnesium chloride, retarding agents and corrosion inhibitors; and the inner mold is a lightweight material made of expanded polystyrene particles. Waste products such as the plaster power, the pulverized fuel ash and red mud solid powder waste materials in thermal power plants and aluminum manufacturers are used as raw materials; few modified additives are added; the prepared plasterboard can form a continuous waterproof layer; good elongation percentage and breaking strength are realized; the waterproof, sound-proof and anti-seismic effects are good; the acid-resistant and alkali-resistant performance is good; the weather-resistant performance is excellent; the adhesive force is strong; the mildew proof performance, the anti-bacterial performance and the durability are excellent; and in the use process, the construction is fast and convenient.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a cast-in-place lightweight wallboard and floor covering. Background technique [0002] Traditional partition boards are plastered with fired bricks, and fired bricks need to occupy land and fetch soil, and be fired through a kiln, which not only causes serious damage to land resources, but also consumes a lot of energy. With the development of the construction industry, gypsum blocks have been used as partition boards, but their strength is low, their bending resistance and impact resistance are poor, and the wall has no hanging load-bearing capacity, which is prone to cracks. Moreover, the sound insulation effect, waterproof performance, The fire performance and earthquake resistance are very poor, and it cannot be used as an exterior wall partition, so that the use position is limited and the market competitiveness is small. [0003] The development of new wall materials can...
