Abstract: In this experimental study, the properties of recycled aggregate and coconut shell aggregate concrete are examined and the scope of recycled aggregate and coconut shell aggregate in construction is investigated. The basic properties of recycled and coconut shell aggregate concrete are examined wrtthe natural aggregate concrete. Basic changes in all aggregate properties were determined and their effects on concreting work were discussed. Basic concrete properties like compressive strength, split tensile strength, workability etc. are conducted here for different combinations of recycled and coconut shell aggregate.
