In the last two decades the concrete production has increased dramatically leading to the increase in Portland cement production and a huge increase in the production of Green House Gases (GHG) which contribute to global warming.
With the growth in urbanization and industrialization a considerable quantity of industrial byproducts (fly ash, silica fume, slag etc.) are posing serious environmental issues.
The focus of this research is to emphasis the benefits of using the industrial byproducts as supplementary cementitious materials (SCM) as a partial cement replacement in concrete. These materials are both reliable and suitable in promoting the environmental sustainability. This research will also document any existing methods available in applying the cost effectiveness of projects using industrial byproducts as SCM.
A part of the research is to determine the cost effectiveness of using the industrial byproducts as supplementary cementitious materials. And to develop a comprehensive program to extrapolate the cost effectiveness of using them as SCM.
The data obtained from various projects will be used in a model to analyze the cost effectiveness of the project. Based on the data collected from various agencies, a simulation model will be developed.
Simulation model will simulate the cost effectiveness of using different byproducts for projects in the future. The effect on environment will also be simulated by showing the reduction in greenhouse gases.
This research on cost effective analysis will be a future guide to the graduate division in creating a more cost effective and environmentally friendly concrete.
