Microstructural Analysis and Synthesis of Organic Geopolymer Matrix

Abstract

Organic polymer resins generally cannot withstand temperatures exceeding 300°C, making them non-fire-resistant. However, inorganic alumino silicate polymers, synthesized by sodium silicate and sodium aluminate, have good thermal properties. This article discusses the synthesis of a geopolymer resin matrix based on different concentration ratios. The compositions of various constituent elements for the geopolymer matrix were varied, and hardeners were added with liquid solutions. The primary materials used are liquid sodium aluminate solution and sodium silicate solution, which are mixed with smaller quantities of fly ash and metakaolin. Several samples of geopolymer matrix were prepared and cured at elevated temperatures to remove water content. There was minimal shrinkage during curing. Microstructural tests were conducted to confirm the formation of a viable geopolymer resin, and the results confirmed the successful development of the geopolymer.
