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.
