Abstract

The maintenance and repair work in the civil engineering infrastructures develops the production of huge wastes which causes the growth of waste piles, additional costs in construction projects and some environmental problems. If this waste is recycled and used again in construction projects, it will help to overcome the problems discussed earlier. Moreover, if natural aggregates are supplemented by recycled aggregate, it will preserve the natural resources and also put a pause in the deterioration of natural landscape.

This thesis addresses the importance of using recycled aggregate in concrete structures. Its practical feasibility in construction projects is studied in light of the work done by the previous researchers. The concrete mix with optimum amount of recycled aggregate is developed which is further evaluated for the mechanical properties in accordance of ASTM and AASHTO guidelines. Moreover, the optimized mix is evaluated for the benefit to cost analysis. It is then concluded that the use of recycled aggregate in concrete structures is feasible both in quality and cost point of views.
