Synthesis and characterization of a concrete based on metakaolin geopolymer
Source abstract
Abstract
Inorganic alumino-silicates polymer or geopolymers are amorphous materials with a chemical composition similar to zeolites and an empirical overall chemical formula: M n [−(SiO2) z −AlO2] n · wH2O where M is an atom of metal (Li, for example), and n, z, w - integers. This paper describes the synthesis and characterization of a concrete based on metakaolin geopolymer. In addition, its physical, mechanical and thermal properties are compared to those of a concrete based on portland cement. It was observed that the compressive strength properties in the concrete based on metakaolin geopolymer were higher than those in the concrete based on portland cement; besides, thermal conductivity was lower for the former than for the later. Those differences are attributed to intrinsic nature of the binding phase.
