Abstract : Due to the shortage of space for land reclamation in Qena Governorate, it is difficult to dispose tons of construction, Adoption of recycled aggregate from concrete waste. Most of studies held in Qena Governorate on recycled aggregate produced from construction and demolition wastes, focused on using recycled aggregate as granular material for base coarse roads and for concrete mixes for concrete hollow blocks. The percent of fine recycled aggregate in the all recycled aggregate was about 9.0% so it was excluded from the study. 0 % and 40 % of coarse recycled aggregate was used in the experimental tests. Two kinds of natural fine aggregates were used, Qena sand and crushed stone. The experimental tests focused on, physical properties density and workability, and mechanical properties compressive strength, flexural strength and bond strength between concrete and steel in raft foundation for example. More than 70 concrete specimens were tested for the study. The tests showed that the workability of recycled aggregate is lower than the workability of natural aggregate concrete ,the slump test was about 1.0cm slump for 40 % coarse recycled aggregate concrete and increases as the percent of recycled aggregate decreases . The compressive strength of recycled aggregate concrete with 40 % recycled aggregate, is about 85% of natural aggregate concrete. The compressive strength increases as the Percent of recycle aggregate in concrete mixes decreases. Keywords- Recycled Aggregate, Compressive Strength, Raft Foundation, Natural Aggregate
