Coal ash foamed bricks stabilised with hydrated limeactivated GGBS (HL-GGBS) / Mohamad Ezad Hafez Mohd Pahroraji [PDF]
, 2017 Coal-fired thermal power plant produces million tonnes of coal ash as an industrial by-product and is significant to be used as raw material for fabrication of bricks. Coal ash could potentially substitute the traditional materials i.e.

Advanced Science, Volume 12, Issue 26, July 10, 2025.The global energy demand drives the need for advanced energy‐efficient building solutions. While current polymeric‐shell microencapsulated PCMs show promise for thermal energy storage, their use in cementitious materials is challenged by poor shell strength and interfacial bonding. This study develops novel cement‐compatible microencapsulated PCM using

Valorization of Mine Tailings for Sustainable Geopolymer Production
International Journal of Ceramic Engineering &Science, Volume 7, Issue 4, July 2025.ABSTRACT The sustainable production of geopolymers requires innovative approaches to raw material utilization. This study investigates the valorization of sulfidic coal mine tailings as a partial substitute for metakaolin in geopolymer synthesis. A comprehensive protocol involving mechanical grinding, particle size reduction (<5 µm), and thermal ...

Magnetic Resonance in Chemistry, Volume 63, Issue 7, Page 476-494, July 2025.Six calcium silicates with Ca/Si ratios from 1 to 3 have been exposed to aqueous carbonation at ambient conditions and characterized by 29Si and 13C MAS and CP/MAS NMR spectroscopy. The analysis reveals that the structure and composition of the produced silica gel is independent of the starting materials Ca/Si ratio.

Effect of light‐cured pulp capping materials on human dental pulp cells in vitro
International Endodontic Journal, Volume 58, Issue 7, Page 1060-1072, July 2025.Abstract Aim Gold standard as material in vital pulp therapy (VPT) is hydraulic calcium silicate cements (HCSC). To circumvent their prolonged setting time, light‐cured pulp capping materials containing calcium silicate or calcium hydroxide powder are available.
