Title : Calalsil™ Zeolite Geopolymers – Green nanotechnology that replace carbon and energy intensive materials

Abstract:

Abstract: Zeolite geopolymers are formulated using nano-sized colloids of combined metal oxides to provide a green alternative to concrete, brick and fiberglass. While suspended in an aqueous solution, CalAlSil™’s nano-colloids contain sufficient chemical potential to cure to solid structures with physical properties equal or better than standard concrete. This represents a great leap forward in ease of use of structural materials and the ability to produce composites with almost all other granulated materials establish CalAlSil™’s credentials as the green keystone formulation for the circular economy. CalAlSil™’s suspensions are produced using organic and organometallic complexing agents combined with aqueous alkali silicate solutions. Stable suspensions were produced with molar equivalent reactive oxides found in fly ash from black coal fired power stations, ball clay, aluminium trihydrate, and calcium hydroxide. Solutions may be hybridized with a number of biopolymers and standard resins including aqueous acrylic and siloxane suspensions, silicone oil, terpene resin, natural latex, poly lactic acid and numerous polyethers.

CalAlSil™ non-combustible resins and hybridized resins can be used in a range of applications including as coatings to wood, concrete, masonry, steel, aluminum and medium–high energy plastics as well as combining resins in composites using a wide range of granulated and fibrous materials from almost any waste stream. CalAlSil™. The adhesion and cohesive strength of coatings and composites have been measured and compared with similar carbon and energy intensive materials currently in use. This new class of hybrid polymer between inorganic and organic materials provides the next step in materials development for the industrial and built environments.
