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.}, keywords = {Reduced-graphene oxide,cement,CCD,Compressive strength,Flexural Strength}, url = {https://www.jcema.com/article_92049.html}, eprint = {https://www.jcema.com/article_92049_4281ddecffbbfcebe8159369b2af705f.pdf} }
