Definitions

  • This invention pertains to methods of manufacturing cement or concrete building materials. More particularly, the invention relates to methods of manufacturing autoclaved cellular concrete products utilizing waste or by-product from the burning of coal. Thus, the invention relates to both a method for manufacturing building materials and a method for utilizing an environmentally undesirable waste product to produce useful materials.
  • fly ash When coal is burned, airborne by-products, such as carbon dioxide, sulfur dioxide gas and airborne ash, known as fly ash, are produced. In the United States, statutes, such as the U.S. Clean Air Act, have been enacted to reduce the release of these by-products into the environment.

Abstract

L'invention concerne un procédé de fabrication de produits de béton cellulaire traité à l'autoclave, qui repose sur l'utilisation de mâchefer. Le procédé consiste 1) à sélectionner une quantité adéquate de mâchefer, 2) à transformer le mâchefer en fins granules afin d'augmenter sa surface totale et d'exposer ses composés silicatés, 3) à mélanger le mâchefer transformé à de l'eau pour former une suspension épaisse, 4) à mélanger le béton, de la chaux et de la poudre d'aluminium dans la suspension pour former des cristaux de silicate de calcium, 5) à verser la suspension dans des moules pour former divers composants de construction, 6) à faire durcir dans un premier temps la suspension dans les moules à température et à pression atmosphérique ambiantes, et 7) à faire durcir la suspension dans les moules au moyen de la pression de surface, la température et la vapeur afin de transformer les cristaux de silicate de calcium en Tobermorite.
