Effect of Micro- and Nano-Zeolite/Silica Fume on the Mechanical and Durability Characteristics of Reactive Powder Concrete [PDF]

JES: Journal of Engineering Sciences
Silica fume is an essential additive in Reactive Powder Concrete (RPC), as it promotes hydration and densifies the microstructure. In this research, silica fume was partially or fully replaceded with zeolite, introducing a novel 1:1 calcinated zeolite ...
