Relative Characteristics of Various Nano-Cement Composite

Abstract

A comparative study between two nano cementitious materials, i.e., Graphene Nanoplatelet (GNP) and Montmorillonite Nano Clay (MNC) cement matrix are considered in this paper. Nanofibers are introduced as an alternative to macro reinforcement to enhance the mechanical property and reduce the crack growth in the cement matrix at the nanoscale. Various analytical simulation has been carried out by ANSYS 15.0 to know the optimum percentage of water. A 3D Represent Volume Element (RVE) is used to simulate nano cementitious material as the material sizes differ. RVE is the minimum volume upon which a measurement can make, yielding an expected value of the entire. The GNPs and MNCs are added to the cement matrix with various percentages (0.02%, 0.08%, 0.1%, 0.15%, 0.17%, 0.22%, and 0.3%) by the weight of cement. After simulating the pullout models with proper boundary conditions, the behavior of nano-cementitious material is observed. A comparative study of all percentage variations revealed that the mechanical property increases up to 0.17% and 0.22% for GNPs and MNCs. It also observed that GNPs cementitious material performs better than MNCs cement matrix.
