Strength properties of self-compacting concrete prepared with recycled coarse aggregate and manufactured sand

There is great demand in the construction industry to adopt new processes which have negative impact on the environment. This paper presents the utilization of recycle coarse aggregate and manufactured sand on the strength properties of self compacting concrete (SCC). SCC mixtures were prepared with different replacement levels of recycle aggregate and Msand with a Water/Binder ratio of 0.36. Fresh properties and mechanical properties of these SCC mixtures were tested and the results were compared with EFNARC guidelines and also with past literature papers. Combining these two materials in production of SCC presents environment and economic advantages of using these materials leading to an new material which can be used in construction industry.
