Mechanical Properties of Field Demolished Aggregate Concrete

This paper studied about the mechanical properties of field demolished aggregate concrete. The demolished concrete from previous construction, after surface treatment is used as aggregate known as recycled aggregate. The present work is studied by replacing the recycled aggregate with natural coarse aggregate from 0% to 50% at every increment of 10% in M 30 grade of concrete.
