Effect of polymer admixtures on metakaolin-based geopolymer
Original language description
Geopolymers are presented in many studies as binders alternative to ordinary Portland cement. Several inorganic materials have been used as raw materials for the production of geopolymers. One of them is metakaolin which is produced by dehydroxylation of kaolin. Metakaolin has a much larger surface area than cement, resulting in an increase in water demand to maintain workability. Polymer admixtures may contribute to reduction of this demand. However, another problem should be considered: plasticizers which improve rheological properties in cement technology are not effective for geopolymers. The aim of this study was to analyze the effect of different polymer admixtures on the compressive and flexural strength, pore size distribution and microstructure of alkali-activated metakaolin material. The results revealed that a maximum compressive strength of 18.6 MPa was achieved by adding 1.5% of VINNAPAS 7016 F, and a maximum flexural strength of 2.2 MPa when adding 0.5 or 1% of the same polymer admixture.
