Environmentally Friendly Pervious Concrete for Treating Deicer-Laden Stormwater: Phase II [PDF]
In Phase I of this project, graphene oxide (GO)-modified pervious concrete was developed using coal fly ash as the sole binder. The primary objectives of Phase II of this project were (1) to evaluate the stormwater infiltration capacity of GO-modified ...

Enhancing the Reactivity of Dicalcium Silicate Using Aluminum and Sulfur Ions Co‐Doping
ABSTRACT Belite‐rich cements are a lower‐energy and lower‐CO2 alternative to Portland cements, but the low hydraulic activity of belite remains a major limitation. This study explores the impact of aluminum and sulfur co‐doping on the structure and hydration of synthetic dicalcium silicate (C2S).

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 ...

(Micro)-structural comparison between geopolymers, alkali-activated slag cement and Portland cement [PDF]
Concurrently to research conducted on ordinary Portland cement (PC), new types of binders were developed during the last decades. These are formed by alkali-activation of metakaolin or ground-granulated blast furnace slag (GGBFS) and are named, respectively, geopolymers (GP) or alkali-activated slag (AAS).
