| Popis: | Nanotechnology has already had an effect on a number of areas, including civil engineering. Cementitious composites containing a variety of nanomaterials have been identified as a novel material with enhanced microstructure, mechanical, and durability properties. In the world of civil engineering, graphene oxide has recently emerged as one of the most promising nanomaterials. However, adding graph oxide to the cement mortar improves compression strength, tensile strength division, and bending strength. The ultra-high-resolution field scan microscope (FE-SEM) showed that the cement matrix was well dispersed and no aggregates were found in samples with fracture surfaces of 0.08 percent GO to weight from cement. When comparing the growth of calcium silicate hydrates in GO cement mortar to regular cement mortar, SEM results showed that GO cement mortar grew faster (C-S-H Gel). |
