As the usage of fine aggregates is increasing day by day so we have to use economical alternatives. We replaced sand with proportions of steel mill scale in self compacting concrete. After curing of 28 days different test were performed and results were obtained. Results showed that upon 40% replacement of sand with steel mill scale the strength increases and goes on decreasing afterwards.
Project Objective
- To determine the effects of partial and full replacement of Sand with Steel Mill Scale on the properties of the self-compacting concrete.
- To carry out life cycle assessment of self-compacting concrete.
- Socio-Economic Benefits Steel mills scale is a waste product produced during the manufacturing of steel in steel industries. Most of the industries used to dump this waste in river water, lakes, etc. Which is harmful to aquatic life. So it’s a good idea to use waste materials in some proportion in concrete. This will be beneficial for the environment because the use of fine aggregates will be reduced to some extent as we will be replacing them with waste materials. Steel mills scale being a waste material is more economical than sand, so economical concrete can be made.
- Project Methodology
•Materials
•Trails (For SCC)
Trials were done for the selection of suitable w/c ratio and some other tests were performed like V-funnel and L-box tests to check the flow of concrete.
•Sample Preparation
Cylinders were made for 7 different mixes.
•Testing
Compressive tensile flexural and several other tests were done at intervals of 7,14 and 28 days.
•Results
obtained results showed an increase in strength up to 40% addition of steel mill scale.
•Life Cycle Assessment
It will be done using LCA and Revit.
1. We will be able to study the effect of steel mill scale in different proportions on the strength of concrete.
2. We will be able to make high-density concrete.
3. Life cycle assessment of SCC.
