HighlightsThe produced SCBA in 800C and 30min is optimal in terms of reactivity.SCBA and nanosilica were found to be effective up to 20% of binder weight.The SP dosage of the SCBA and nanosilica blends was higher than the control sample.SCBA and nanosilica reduced the permeable pores due to filler effects.SCBA and nanosilica improved the migration coefficient at later ages.
AbstractInfluence of nanosilica and sugar cane bagasse ash (SCBA) on the mechanical and durability properties of mortar, is investigated in this study. Sixteen mortar mixtures were designed with a particular water to binder ratio of 0.485 and a sand to binder ratio of 2.75. Test specimens were prepared with 3% and 6% replacement of cement weight with nanosilica and a 10–30% replacement of cement weight with SCBA. A compressive strength test was applied to evaluate the mechanical performance of mortars containing nanosilica and SCBA. In addition, transport tests, chloride permeability, electrical resistivity and mercury intrusion porosimetry of single, binary, and ternary blended mortars were conducted to investigate the influence of replacement materials on durability properties of mortars. Nanosilica improved mechanical and durability properties of mortar, while SCBA did not have a substantial influence on mortar performance according to lower strength and durability at early ages. The addition of SCBA in mixtures containing nanosilica intensely decreased compressive strength at the ages of 3days and 7days. However, ternary mixture results showed the best performance in the long term.
