(DSCFST) columns have superior strength, stiffness and ductility to that of traditional …

Shrinkage of concrete refers to the volumetric change of concrete due to cement hydration
(ie, self‐desiccation) and environmental drying (ie, water evaporation). It creates …

Despite its established reputation and extensive testing as an alternative to conventional
cement, geopolymer continues to heavily rely on natural aggregates. The disposal of waste …

Ultra-high performance concrete (UHPC) encounters hindrance in pursing carbon neutrality
and extended applications due to the dosage of cementitious materials and high energy …

Sand and gravel are the world's most exploited resources, even surpassing fossil fuels; they
are mostly used for producing concrete. On the one hand, due to restrictions on the use of …
