design and optimization of mechanical properties of reduced-graphene oxide- loaded cement

graphene oxide (go) is a graphite-based product. go prepare a new distance to interact with cement matrix. go due to the high specific surface area, high intrinsic mobility and high young’s modulus leads to a remarkable enhancement in mechanical properties of cementitious material matrix.

in the present study, the effect of reduced-graphene oxide (r-go) on the mechanical properties of portland cement paste was investigated. response surface methodology based on central composite design (ccd) was used to predict the interaction effects of curing time (7-21 days) and go amount (0.02-0.1%) on the compressive strength and flexural strength of the r-go–cement composite.

by optimization of parameters, the compressive strength and flexural strength was increased by 48% and 74% compared with cement without r-go. the obtained results demonstrated that the r-go is a promising filler of cement-based composites to enhance the mechanical properties of cement.
