Light-weight phase change aerated concrete, building body wall and construction method of building body wall

Abstract

The invention provides light-weight phase change aerated concrete, a building body wall and a construction method of the building body wall. The concrete is prepared from the following ingredients inparts by weight: 35 to 40 parts of fly ash, 10 to 16 parts of glazed hollow beads, 10 to 12 parts of graphite-containing paraffin powder, 12 to 15 parts of quicklime, 10 to 13 parts of cement, 2 partsof gypsum, 0.1 to 0.2 part of aluminum powder, 0.01 part of polypropylene fiber, 0.3 to 0.6 part of water reducing agents, 0.2 part of polyacrylamide and 1 to 3 parts of stearic acid. The light-weight phase change aerated concrete building body wall prepared from the concrete comprises a Z-shaped structure main body, a cuboid structure matched body and a mortar layer. By using a construction method with the steps of weighing, material taking, stirring, casting, cutting, caring, wall body building and integral wall body care, the wall body is obtained. The light-weight phase change aerated concrete, the building body wall and the construction method provided by the invention have the advantage that excellent waterproof performance and heat insulation performance are realized; high stability is realized.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a lightweight phase-change aerated concrete, a masonry wall and a construction method thereof. Background technique [0002] The traditional aerated concrete block is a light and porous building material. It is made of cement, lime, slag, fly ash, sand, gas-generating materials, etc., after grinding, batching, pouring, cutting, steaming It has the advantages of light weight, certain thermal insulation performance and machinability, but it has single variety, high cost, low strength, large drying shrinkage value, difficult to control pouring stability, and general frost resistance. And other indicators do not meet the requirements of the specification, and the scope of application is limited. [0003] Starting from the needs of people's lives, buildings should have a certain thermal insulation performance, and this performance is realized through good thermal insulation material...

AI Technical Summary

Problems solved by technology

Most of the thermal insulation materials in the past are plates, sheets, blocks and other shapes made of fibrous, granular or microporous materials. The limitations of these materials or manufacturing methods have the problem of generally low strength, and these The material mainly relies on the low thermal conductivity of still air to reduce the heat conduction of the material, but it is difficult to prevent the heat conduction in the direction of the temperature gradient, and it cannot automatically adjust the air with the change of the ambient temperature

The six sides of the traditional aerated block are flat and straight, and the masonry wall has poor integrity, weak deformation resistance and low rigidity
