The influence of rice husk ash addition on the properties of metakaolin-based geopolymers [PDF]

, 2016
This paper investigates the replacement of metakaolin (MK) with rice husk ash (RHA) in the production of alkali-activated binders or geopolymers. The influence of the RHA addition on compressive and flexural strength, as well as water absorption and ...

Elevated Temperature Behavior of Bagasse and Human Hair Fiber‐Reinforced Fly Ash Geopolymer Composites

Engineering Reports, Volume 7, Issue 12, December 2025.
This study demonstrates that human hair fiber‐reinforced fly ash geopolymer composites outperform bagasse‐based counterparts at elevated temperatures. They show higher mechanical strength, less thermal weight loss, and stronger fiber–matrix bonding, making them promising sustainable reinforcements for thermally demanding applications.
