Construction and Building Materials 156C, 1150-1157 (September 2017). https://doi.org/10.1016/j.conbuildmat.2017.09.072 Highlights - The influence of graphene oxide (GO) addition on a NHL mortar was studied - Better results were obtained with water dispersed GO in comparison to powder GO - Mineralogical testing did not identify the GO compounds on mortars - GO in 0.05 and 0.1 wt.% lead to a slight improvement of mechanical characteristics - GO in 0.1 wt.% provided better durability to liquid or vapour water action New composite of natural hydraulic lime mortar with graphene oxide Paulina Faria 1 , Paulo Duarte 2 , Davide Barbosa 3 , Isabel Ferreira 4 1 CERIS and Department of Civil Engineering, Universidade NOVA de Lisboa, Portugal, [email protected] 2 LAQV - REQUIMTE, Department of Chemistry, and CENIMAT/I3N, Department of Materials Science, Universidade NOVA de Lisboa, Portugal, [email protected] 3 Department of Civil Engineering, Universidade NOVA de Lisboa, Portugal, [email protected] 4 CENIMAT/I3N and UNINOVA, Department of Materials Science, Universidade NOVA de Lisboa, Portugal, [email protected] Corresponding Author: * [email protected] Keywords: Graphene oxide; natural hydraulic lime; mortar; microstructure; mechanical property; physical property
