This paper presents an experimental investigation on the effect of replacing natural coarse aggregate by recycled aggregate obtained by processing field demolished concrete on the properties of recycled aggregate concrete. The natural coarse aggregate (NA) in concrete was replaced by recycled coarse aggregate (RA) at different percentages. Workability tests and strength tests such as compressive test, tensile test, flexural test and impact test are conducted to study the effect of replacing NA by RA. Test results show that for different percentage replacements of natural coarse aggregates by recycled aggregates there is a reduction in strength of concrete with the increase in the percentage of replacement. For replacement of natural aggregates by recycled aggregates up to 20%, the reduction in strength was marginal.
