Mechanical performance of glass-based geopolymer matrix composites reinforced with cellulose fibers [PDF]

, 2018
Glass-based geopolymers, incorporating fly ash and borosilicate glass, were processed in conditions of high alkalinity (NaOH 10-13 M). Different formulations (fly ash and borosilicate in mixtures of 70-30 wt% and 30-70 wt%, respectively) and physical ...

STABILIZED MORTAR CONTAINING METAKAOLIN

, 2022
Several residues have potential for use in mortars and concrete, such as wastes from kaolin production (KW). So, this article aimed to study the use of metakaolin (MK) from the KW as partial replacement for Portland cement in stabilized mortars with 10% and 20% content in order to also contribute to the stabilization time.

Highly porous mullite ceramics from engineered alkali activated suspensions [PDF]

, 2018
Air may be easily incorporated by vigorous mechanical stirring, with the help of surfactants, of activated geopolymer-yielding suspensions. The cellular structure is stabilized by the viscosity increase caused by curing reactions, configuring an ...

Metakaolin

, 2017
Metakaolin (MK) is known to be a highly pozzolanic material that can be used in concrete. MK is usually produced by heating kaolin-containing clays, within the temperature range of about 600–900 ℃. This chapter summarizes the utilization of metakaolin in relevant worldwide standards, mainly in Europe and North America.

Enhancing printability of 3D printed concrete by using metakaolin and silica fume

Structural Concrete, EarlyView.
Abstract This study investigates the effects of incorporating metakaolin (MK) and silica fume (SF) on the fresh and hardened properties of 3D printed concrete (3DPC). Five mix designs were prepared with MK replacement levels of 0%, 10%, 12.5%, and 15%, along with one mix containing 10% MK and 5% SF.

Optimization and predictive modelling of biodiesel production from waste cooking oil catalyzed by blast furnace slag geopolymer using RSM and machine learning

The Canadian Journal of Chemical Engineering, Volume 104, Issue 1, Page 6-30, January 2026.
Abstract Biodiesel production from waste cooking oil (WCO) has emerged owing to growing interest in sustainable energy sources. Geopolymers synthesized from industrial wastes, such as blast furnace slag (BFS), are promising catalysts because of their environmental benefits and catalytic properties.
