Sustainable Development of Mortar Using Fly-Ash Waste with Incorporation of Carbon Nanomaterials

This study investigates capillary section test (CST), electrical resistivity, acid and sulfate attack on HVFA-based mortar incorporated with 0.005% of Graphene Oxide (GO). The CST test results indicated that the introduction of GO in HVFA-based mortar led to the lowest water absorption levels observed. The electrical resistivity was found to be 52.17 k-ohm-cm for 0.005 wt% of GO at curing age of 90 days. Moreover, compressive strength of HVFA-based mortar was found at 10.91 MPa and 32.35 MPa for acid and sulfate attack, with the incorporation of GO at curing age of 90 days. Moreover, the study aimed to develop sustainable, cost-effective, and more durable HVFA-based mortar.
