Definitions

  • Aerated concretes have a significant number of advantages. Firstly, they are often environmentally friendly to produce, decreasing harmful greenhouse gas emissions. They are typically energy saving to both produce, and in operation, particularly in building related applications, where the aerate nature of the material has comparatively high heat insulation properties.
  • a general method of making AAC or LCC requires the use of aluminum powder for aeration.
  • Aluminum dust generated in the process of making AAC creates an occupational health and safety concern for workers involved in its production.
  • Aluminum powder is potentially explosive if exposed to certain chemicals, static electricity, high temperature and humid conditions.
  • use of aluminum powder as a source of aeration in AAC or LCC is often un-controllable and results in a non-homogenous void structure within the final product which deteriorates the structural properties of the building panel.
  • a plurality of very fine filaments of carbon 9 are also included.
  • the filaments of polymer and carbon, 7 and 9 respectively, combine with the geopolymer 3 to form a micro concrete through the walls between the gas filled voids 5. This creates an advantage where the material maintains its air pores during the pouring, and curing process, and mitigates the problem of gas bubble migration or merging.
  • the building panel has significantly increased flexure load resistance, and can also withstand greater vibration loads from exposure to geological events, such as earthquakes and tremors.

Abstract

La présente invention concerne un mélange de béton aéré comprenant une matrice de vides remplis de gaz de taille sensiblement uniforme et distribués de manière uniforme à l'intérieur d'un matériau géopolymère, les vides remplis de gaz conservant sensiblement leur position et leur forme, pendant le procédé de durcissement du géopolymère ainsi qu'après son achèvement. L'aération est introduite dans le géopolymère à l'aide d'une mousse qui est doucement mélangée dans le mélange de sorte qu'elle est apte à conserver son effet d'aération sur le géopolymère. Une pluralité de fines fibres de polymère peuvent ensemble, ou individuellement, être incorporées dans le géopolymère, et les fines fibres de polymère sont réparties de manière sensiblement uniforme à travers le matériau géopolymère et intercalées entre la matrice des vides remplis de gaz.
