SHORT DESCRIPTION A new method for the synthesis of metakaolin based geopolymer with evenly dispersed nano reinforcements that improve strength and elasticity of material.
ABSTRACT Geopolymer nanocomposites combine a high level of multifunctionality with extraordinary mechanical characteristics. The enhanced-performance low-density multifunctional metakaolin-based nanomaterials are reinforced with multiwalled carbon nanotubes and nanofibers for applications such as structural engineering, aerospace, energy and marine engineering. Current methods of construction lack the ability to evenly disperse the nanomaterials within the solution. This leaves the product porous which limits the performance of the geopolymer. Therefore, a novel method to synthesize uniformly dispersed metakaolin-based geopolymer nanocomposites has been developed by Ange-Therese Akono and Jiaxin Chen. The uniform dispersion results in a less porous final product which strength and fracture toughness. This technology also has the ability to lower CO2 emissions by reducing the amount of carbon dioxide created in the manufacturing process, compared to commercial cement manufacturing. Since there are many different applications for this technology and there is a widely established market, implementation of this method within companies would decrease carbon emissions and increase strength of their product, possibly reducing long term costs.
