Assessment of the Mechanical Properties of High Strength Mortar Incorporating Silica Fume and Graphene Nanoplatelets: Experimental and Mathematical Modeling

Cement-based mortar is recognized as a popular and cost-effective material for the rehabilitation repair of reinforced concrete structures. However, development high-performance cement-based in high demand order to not only enhance compressive strength but also prolong lifespan minimize maintenance costs much possible. In current study, high-strength mortars incorporating both silica fume graphene nanoplatelets (GNPs) were investigated evaluated based on flexural strength. The powder was added amounts ranging from 0.5% 2%, by cement weight, while partial replacement (10%). optimal content determined using response surface methodology (RSM). addition, field emission scanning electron microscopy (FESEM) used assess proposed at micro-scale level. outcome revealed that graphene-based imparted superior mechanical properties compared control mixture. containing 10% 1% increased 33% 35%, respectively. This positive result attributed refinement nanopores tiny cracks inclusion GNPs, which supported microstructure testing. RSM model shown be capable optimizing predicting with less error. It possible conclude will serve sustainable near future.
