Investigating Pozzolanic Reactivity of Ground Ferronickel Slag Through the R 3 Test for Its Potential Use as Alternative Supplementary Cementitious Material

International Journal of Concrete Structures and Materials
This study investigates the pozzolanic reactivity of ferronickel slag (FNS), the fourth most discharged smelting by-product in China. Cumulative heat of hydration (R3) tests were conducted on FNS with varying fineness levels (111.27 to 4.5 μm) to compare

The effect of various chemical activators on pozzolanic reactivity: A review

Scientific Research and Essays, 2012
Pozzolans are being extensively used as a partial cement replacement in the production of Portland cement concrete. The advantages of using pozzolans are lower costs and better durability, however it requires longer setting time and the strength development at the initial age is slower.
