Mechanical properties and durability performance of fly ash based mortar containing nano- and micro-silica additives

The aim of this paper is to investigate the influence of nano-silica (NS) and micro-silica (MS) on the properties of fly ash based geopolymer mortar. The use of such additives has the potential to provide greener and cheaper concrete with enhanced properties. A screening study was conducted to compare the performance of mortar containing varying percentages of NS and MS (up to 15%). The performance of each specimen was determined through tests...
