Properties of Calcined Clay-Based Geopolymer Mortars in Presence of Alccofine Powder and Recron Fiber
Geopolymer mortars were prepared by treating calcined clay (CC) with sodium hydroxide and sodium silicate solutions in the presence of alccofine powder (AF) and recron fiber (RF). Alccofine powder increased the compressive strength of geopolymer mortar due to increased geopolymerization and filling of the pores. Recron fiber on the other hand decreased the strength. This was due to water absorption by the fiber. SEM was used to study the morphology. Rapid chloride permeability test showed that geopolymer mortar in the presence of AF is much more durable as compared to other mortars in the absence of AF. Durability of mortars in sulfuric acid indicated that geopolymer mortar containing AF is quite durable as compared to that containing RF. The overall results have shown that calcined clay of high surface area on reaction with concentrated NaOH (14 M) in the presence of AF gives mortar of high strength even at room temperature curing.
