Experimental Study on Metakaolin and GGBS Based Geopolymer Concrete

Effect of Glass Powder and GGBS on Strength of Fly Ash Based Geopolymer Concrete

In this study, the effect of glass powder (GP) and ground granulated blast furnace slag (GGBS) on the compressive strength of Fly ash based geopolymer concrete has been investigated. The mass ratio of fine aggregate (fA) to coarse aggregate (CA) was maintained constant. NaOH flakes dissolved in water was used as activating liquid and mixed with fly ash (FA) to produce geopolymer paste or cement...

Study of Metakaolin-Based Geopolymer with Addition of Polymer Admixtures

In the present work, metakaolin-based geopolymer including different polymer admixtures was studied. Different types of commercial polymer admixtures VINNAPAS® and polyethylene glycol of different relative molecular weight were used as polymer admixtures. The main objective of this work is to investigate the influence of different types of admixtures on the properties of metakaolin-based geopol...

Rheology of Geopolymer: Comparative Study between Portland Cement and Metakaolin Based Geopolymer

Metakaolin based geopolymers are presented in many studies as an alternative to normal Portland cement. Previous studies have focused on their chemical and mechanical properties, their microstructures and their potential uses, but very few on their rheological behaviour. Our work highlights the main differences that exist between geopolymer and Portland cement. These materials behave as Newtoni...

The heavy metal adsorption characteristics on metakaolin-based geopolymer

Application-Oriented Chemical Optimization of a Metakaolin Based Geopolymer

In this study the development of a metakaolin based geopolymeric mortar to be used as bonding matrix for external strengthening of reinforced concrete beams is reported. Four geopolymer formulations have been obtained by varying the composition of the activating solution in terms of SiO₂/Na₂O ratio. The obtained samples have been characterized from a structural, microstructural and mechanical p...
