A method of manufacturing geopolymer tubes comprises forming a geopolymer composition comprised of an aluminosilicate source and an alkali activator, wherein the geopolymer composition has a fluid consistency and a shear thinning index of greater than 1.05, transferring the geopolymer composition into a tubular mold, rotating the mold to shear and distribute the composition onto the inner wall of the mold until the geopolymer composition reaches non-flowable consistency, and curing the geopolymer in the mold to form geopolymer tubes. A method for making geopolymer tubes with the disclosed geopolymer composition comprises shearing the geopolymer composition in a tubular mold at a high rotational speed to significantly reduce apparent viscosity to form the tubular shape, at least in the initial process stage. A ceramic tube made from the geopolymer composition of the present invention is used as a membrane or adsorbent for filtration applications.

This invention relates to an adaptable Geopolymer cement composition for application in oil and gas wells having a wide range of downhole temperatures. The base Geopolymer cement composition has an acceptable rheology of below 200 cP and can be tailored by the inclusion of various chemicals to control properties such as thickening time over a wide range of temperatures and densities. The disclosed Geopolymer cement composition is pumpable, mixable and stable. The composition can also be adapted to have expandable and swellable properties.

A structural material composition comprises: a geopolymer matrix, the geopolymer matrix formed from an alumina silicate source and an alkaline activator; and an antibacterial agent (e.g. biocide and/or heavy-metal based antibacterial agent) encapsulated in an antibacterial agent carrier to form a first plurality of encapsulated antibacterial agent particles. The first plurality of encapsulated antibacterial agent particles is integrated with the geopolymer matrix during polymerization.
