Statistical Study of the Effectiveness of Surface Application of Graphene Oxide as a Coating for Concrete Protection

Improving the protection of concrete by applying graphene oxide (GO) as a surface treatment has become objective present study. This study focuses on performing statistical analysis to different levels GO application an exterior coating, thus observing effectiveness coating and optimization material for protection. Four tests were performed define durability, such pressurized water penetration, capillary absorption, freeze-thaw resistance carbonation resistance. The results showed increase in durability with any level surface, considering that optimum amount impermeability is 26.2 µg/cm2, since it was possible reduce penetration 45%, absorption 57% detachment 25%. However, rate 52.4 reducing almost 60%. In conclusion, if going be exposed less aggressive environments, mild sufficient its protection, more necessary GO. performance significantly increased degree concrete, increasing service life proving promising
