  • Cellular geopolymer product
    Patent number: 10669214
    Abstract: A method for manufacturing a cellular geopolymer product, which method comprises the steps: (a) forming an activated geopolymer premix by addition to a geopolymer premix of an activator compound that initiates a condensation reaction in the geopolymer premix; (b) casting the activated geopolymer premix in a desired configuration; and (c) generating gas bubbles in the activated geopolymer premix as the condensation reaction proceeds and the activated geopolymer premix stiffens to produce a self-supporting cellular structure; and (d) curing the self-supporting cellular structure to produce the cellular geopolymer product, wherein in step (c) the characteristics of the activated geopolymer premix and the reaction kinetics of the condensation reaction are controlled to achieve formation of the self-supporting cellular structure.

  • Method of making a cementitious product
    Patent number: 8815133
    Abstract: A method of manufacturing a porous cementitious product, which method comprises: forming a cementitious premix; casting the premix in a desired configuration; generating gas bubbles within the premix; and curing the premix, wherein gas bubbles are generated and/or collapsed at specific locations within the premix in order to produce a porosity profile along a cross-section of the product such that the product comprises a relatively low density core region and higher density outer regions.
