Investigational Studies on the Strength and Durability Parameters of Concrete with the Impact of Graphene Oxide and Silica Fume
摘要
In the modern world, using nano-materials has become a new area of technological advancement and their effective functionalities have a significant impact on various fields including the construction field by providing insulation, improving strength, and resisting crack formation. Graphene oxide (GO) is poised to make impact on the construction industry in the coming years due to its oxygenated functionalities that enhance dispersibility, surpassing other graphene-based materials. The quality of dispersion is crucial when utilizing GO as a modifier for cement-based products. The abundance of calcium ions in fresh cement paste can hinder the efficacy of GO, underscoring the necessity to investigate the dispersion mechanism of GO. Graphene oxide (GO) is produced as a result of oxidization of the strongest material graphene which imparts strength, toughness, and higher thermal properties, this study was intended to examine the concrete properties for strength and durability properties, made with silica fume (SF) as the partial replacement to cement by 5%, 7.5%, and 10%, the GO content was introduced with 0.02%, 0.05%, 0.1%, and 0.2%, increased performance in the concrete is observed for the combination of finer materials in the mixes, the 0.05% of GO dosage shown higher strength values and superior resistance under acid attack test.
