The graphical abstract illustrates a circular waste to value pathway in which coal fly ash is upgraded by isolating unburned carbon and converting it into functional carbon materials. Through carbonization and activation, UC‐derived carbon is transformed into high surface area electrodes for supercapacitors, supporting sustainable energy storage and ...

Innovative Application of SRG for Strengthening Continuous RC Beams
Steel‐reinforced grout (SRG) effectively strengthens continuous reinforced concrete beams, enhancing flexural capacity by up to 81%. Using geopolymer mortar promotes sustainability while steel fabrics outperform carbon, glass, and PBO alternatives. Low‐density SRG provides superior bonding and structural efficiency, offering a practical solution for ...
