Problems solved by technology

[0003] The invention patent with the application number 201210125875.5 published on September 12, 2012 discloses a double-foam pumped thermal insulation slurry and its manufacturing method. The slurry is composed of organic foam particles, cement, water, and cement foaming agent. It can not only effectively utilize the characteristics of good thermal insulation effect and high foaming rate of organic foaming materials, but also use the characteristics of good affinity between inorganic foaming materials and building structures, high strength, fire resistance and durability, and extensive resources. The disadvantages are: The production cost is relatively high, and its application number is 201010101103.9. The invention patent polystyrene particle foamed cement composite material mixing and conveying device has the defects of low production mixing efficiency and no automatic control of production.
[0004] The applicant applied for an invention patent with the application number 201310243692.8 on June 19, 2013, a lightweight aggregate foam concrete and its production method. However, it only involves the production and application of concrete raw materials, and fails to realize its mechanized continuous production and on-site pouring, and after further research by the applicant, it is found that the double-foamed foamed concrete produced by the composition material of this application is lighter aggregate Foam concrete has better flexibility and crack resistance, and the product has lower bulk density and higher strength

Abstract

The invention discloses double-foaming cellular concrete and a site production construction method thereof. The volume weight of the double-foaming cellular concrete ranges from 100 KG/M<3> to 400 KG/M<3>; the heat conduction coefficient is as little as 0.020 W/M.DEG C, and the intensity is up to 5 MPa. The double-foaming cellular concrete can be widely applied to the production of light-weight heat preservation materials such as roof heat preservation materials and external wall heat preservation materials and hanging pieces such as light-weight building hanging beams, and has the purposes of the filling of light-weight hollow bricks and hollow building covers; more importantly, the double-foaming cellular concrete can be applied to the construction of underwater facilities. The site production construction method for the double-foaming cellular concrete is simple in technology and simple and convenient to operate; by special equipment, full-automatic integrated productions, such as automatic foaming, metering and proportioning, are effectively realized; upon automatic control, the production construction of the double-foaming cellular concrete is finished highly efficiently at low cost.
