Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

Structural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

High temperature fracture behavior and damage evolution of recycled aggregate concrete produced from metakaolin modified parent concrete

Structural Concrete, EarlyView.
Abstract The increasing use of recycled aggregate concrete (RAC) offers significant environmental benefits by reducing construction and demolition waste; however, its fracture performance and damage evolution under elevated temperatures remain insufficiently understood, particularly when recycled aggregates are derived from metakaolin modified parent ...

Characterization of LUSI Mud as Geopolymer Raw Material [PDF]

, 2012
The mud of mud volcano samples were collected from an eruption site named ‘LUSI’ (Lumpur “mud” –Sidoarjo), East Java, Indonesia for characterization. Analysis showed that, the major constituents of mud are SiO2 and Al2O3 which are higher than those in ...

Assessing Distinctive Physiochemical Properties of Geopolymers, Their Green Development and Utilization in Wastewater Treatment

Water and Environment Journal, EarlyView.
This review examines the physicochemical properties of geopolymers, focusing on the effects of calcium content, heavy metal impurities and acid activation. It distinguishes geopolymers from other alkali‐activated materials based on structure and synthesis precursors. Their use as water treatment adsorbents is compared with ceramic filters, highlighting

Refractory Metakaolin Geopolymers: Achieving High Mechanical Strength and Near‐Zero Shrinkage After Exposure to 800°C

Journal of the American Ceramic Society, Volume 109, Issue 11, November 2026.
ABSTRACT Metakaolin‐based geopolymers are candidate binders for refractory and fire‐resistant components because they combine ceramic‐like thermal stability with low‐temperature processing. Their use is still restricted by a trade‐off: Formulations that develop high strength shrink substantially near 800°C, while formulations that remain dimensionally ...
