The Mechanical and Thermal Properties of Cement CAST Mortar/Graphene Oxide Composites Materials

Abstract This paper presents the influence of graphene oxide (GO) sheet contents at conditions 0, 0.01, 0.03, 0.05, and 0.1 wt% on mechanical thermal properties GO/CAST 11 LW mortar (GMT) composites for heat insulating brick. The GMT were prepared by a simple mixing method. structure was investigated X-ray diffraction (XRD) Raman spectroscopy (Raman) techniques. small grain sizes confirmed transmission electron microscopy (TEM). are increased with increasing GO contents. A lot functional groups in such as carboxylic acid reacted calcium silicate hydrate, CaH 2 O 4 Si (CSH), hydroxide, Ca(OH) (CH) Ettringite, Ca 6 [Al(OH) ] (SO ) 3 ·26H (CA) phases mortar, which can be considered good composites. insulation values improved interaction CSH, CH, CA cement surface GO. highest compressive tensile strengths low transfer rate about 0.465 W/min observed 0.05 (GMT_0.05) curing age 7 days. Thus, new pathway method to significantly improve
