Popis: The aim of the research was to explain how the addition of graphene oxide [GO] to concrete influences performance parameters such as compressive, tensile, and flexural strength, air permeability, sorptivity, absorbability, frost resistance, and thermal conductivity. It was found that the addition of GO in most cases decreased the compressive strength. Nevertheless, an improvement of selected parameters has been observed, eg, an increase in flexural strength by 7% and a split tensile strength by 6% for concrete with GO in the content of 0.005%. Concrete mixes with higher fluidity and improvement of homogenization procedures are suggested for future research areas.
