GO/C2S Nanocomposite as an Environmentally-Friendly Material for sustainable Development of Cement Structure

Abstract

In the present work, Graphene Oxide (GO) nano particles with 0.1, 0.2, 0.4 and 0.8 weight percentages (wt.% ), synthesized by Hummer method entered into the Di-Calcium Silicate (C2S) matrix (synthesized with using Pechini method and their nano structural and mechanical characteristics studied by XRD (X-ray diffraction), FTIR (Fourier transform infrared), GPS 132 A, 4- probe techniques and emission factor analyses. To study and examine GO-C2S nano composites as an environmentally- friendly Material for sustainable Development of Cement Structure 4- capacitor form, with Metal (Al) /GO-C2S composite/ Si substrate are fabricated. The quality factor and dissipation factor were measured by GPS 132 A tool. The obtained results show that sample with 0.4% wt. of GO nano particles has 0.625 fraction emission factor and higher quality factor (32.4), measured at two frequencies of 120 KHz and 1 KHz. Therefore C2S/ GO nano composite with 0.4 wt.% GONs can be therefore introduced as a good additive to reduced emission factor for production of cement and dissipation factor.
