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.

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 ...

Atomistic simulations of water‐driven structural and mechanical changes in N–A–S–H gels
Journal of the American Ceramic Society, Volume 108, Issue 12, December 2025.Abstract This study employs molecular dynamics simulations to investigate the effect of varying water content (0–25 wt.%) and Si/Al ratio (1–3) on the atomistic structure and elastic properties of sodium aluminosilicate hydrates (N–A–S–H) gels. Results show that water molecules break the aluminosilicate framework by forming hydroxyl groups on AlO4 and ...

Microstructure and hydration of interstitial in clinkers produced over molten steel
Journal of the American Ceramic Society, Volume 108, Issue 12, December 2025.Abstract Scalable electrical production of clinker is possible under reducing conditions, and the reactivity of C3A produced in such conditions has only been superficially described. We examined electric clinkers made over molten steel with a range of fineness and compared them against commercial clinkers.
