Fabrication and analysis of mechanical properties of PVC/Glass fiber/graphene nano composite pipes

The aim of this work is to examine the conventional moulding method for manufacturing the PVC/Glass fiber/graphene nano composites. Uniform graphene dispersion is observed with the matrix for better bonding. The Mechanical properties of the manufactured nano composites have been done in this work. Three important standard tests were evaluated for the performance of Nano-Composites developed. The composites were developed as flat specimen for pipe applications. The three standards test which includes axial tension, compression and transverse compression is studied. The graphene nano composites were varied 0.5%, 1%, 1.5% and 2 percentages. Based on the results it can be concluded that the increase in the percentages of graphene made a uniform dispersion, which leads to increase in the compressive strength of the Nanocomposite. Increase in the axial compressive strength and stiffness was observed and the increase in the trend value is mainly observed in 1.5 wt% and 2 wt% respectively. The Graphene dispersion and fractured surface morphology of nano composites were examined using scanning electronic microscopy (SEM).It can also be used as an alternative for metal pipes in industries

Investigation of ferronickel slag powder for marine applications by using MIP method

The main aim of this work is to study the performance of the ferro-nickel slag in the powder form and to analyze the permeability performance using MIP method. The test is carried out under two different conditions. It is performed in clean water and a marine environment. Under these conditions different admixture conditions were examined. The change in impermeability of soil and cements for various admixture conditions were examined and the values were measured. A Mercury Intrusion Porosimeter (MIP) was used to examine the pore structure. Permeability values shown increasing trend in both clean water and in a marine environment. The Impermeability values shown increasing trend in marine environment compared with the clean water. During experimentation when Ferronickel slag powder exceeds 20 percentage. The impermeability reduces gradually and it gets decreased.40 percentages of ferronickel slag powder obtained were seemed to be optimum. Based on the results obtained from Mercury Intrusion Porosimeter (MIP), synergetic integration of ferro nickel slag powder on mixing with the soil-cement creates a micro-aggregate effect and the porosity of soil-cement which in turn increased the resistance for sea water erosions
