Abstract

This work explores the effectiveness of graphene nanoribbons (GNRs) in modifying the fire resistance of cement paste. The GNRs are added to the ordinary Portland cement at 0.10 wt% of the cement, and the sample is heated to target temperatures after curing for 28 days. Subsequently, the variations of compressive strength and pore structure are inquired by compared to the control sample without nano reinforcing and the sample with the same amount of carbon nanotubes (CNTs).
