Abstract: Steel industry is the energy intensive sector directly affecting the growth of the nation. The effect of the restriction put by the government in terms of environmental emissions as well as the costs incurred due to change in environmental practices on the productivity is to be measured. The Green Productivity Index (GPI) is a cumulative index for measurement of the environmental effect and the economic performance. A system model is presented in this paper for analyzing strategy decision making by AHP analysis. A suggestion has been made for implementing the Green Supply chain process for deciding the priority in sequence of Green Manufacturing, Reverse Logistics, Green Marketing, Investment Recovery and Green Purchasing. An attempt has been made to analyze the amount of steel production, energy consumption and emissions in an integrated environmental sustainable framework from primary research data. To benchmark the productivity of a company considering the environmental effect, Gree

Abstract: Based on simple diffusion theory and a timedependent factor (α) for the chloride diffusion coefficient, chloride penetration through concrete was numerically modelled and the service life was predicted. This was done for two reference mixes (normal vibrated concrete, NVC and selfcompacting concrete, SCC) and three other types of sustainable SCC incorporating high levels of cement replacement. All the mixes have a design compressive strength of 50-60 MPa at 28 days with different types of binders. In this study, the non-steady state chloride diffusion coefficients (Dnss) and the surface chloride concentrations (CS), which are mainly used for the numerical modelling of the chloride penetration phenomena, were calculated according to the recommendations of Nordtest methods NT BUILD 443 with the aid of using a developed excel solver tool. The numerical results indicated that the NVC at the same design strength level of the reference SCC showed lower service life and higher depth of cover d
