Development of Sucrose and Citric Acid as the Natural Based Admixture for Fly Ash Based Geopolymer

Geopolymer is the state of the art binder in concrete technology. It utilizes alkaline solution to activate alumina and silica precursors from source material and forms aluminosilicate-based binding material. Nevertheless, the presence of high calcium content in the source material can reduce the...
