Abstract

Sewer refurbishing and concrete restoration and construction may involve the application of shotcrete, which may be pneumatically projected towards the surface in need of repair or construction. This shotcrete includes materials found in basic concrete, such as, sand, Portland cement, and liquid. Previous methods have attempted to alter the material composition of the shotcrete in order to obtain certain benefits. Accordingly, some approaches have involved the use of geopolymers. However, these materials are often subject to corrosion as a result of the organic material inherent in these products. The present invention provides a system and method for applying a construction material is provided. The method may include mixing blast furnace slag material, geopolymer material including non-pumice based volcano rock flour, alkali-based powder, and sand at a batching and mixing device to generate a non-Portland cement-based material. The method may also include transporting the non-Portland cement-based material from the mixing device, through a conduit to a nozzle and combining the transported non-Portland cement-based material with liquid at the nozzle to generate a partially liquefied non-Portland cement-based material. The method further includes pneumatically applying the partially liquefied non-Portland cement-based material to a surface.
