Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Engineering - Department of Civil Engineering Summary: Gaza Strip doesn't have any source of natural aggregate(NA) to reconstruct the demolished constructions .The mega quantities of highly contaminated construction and demolished wastes with heavy metals have to be reused as recycled aggregate(RA) for structural concrete .Using contaminated RA in concrete mixes will minimize leaching of hazardous materials to surrounded environment. RA is highly water absorbable compared with natural aggregate. The concrete made with RA has low mechanical properties especially tensile strength. To study the effect of RA percentage, Polypropylene fiber (PP) , Siloxane polymer(SP) and seawater in concrete mixes, eight types of concrete mixes were prepared. The results showed large enhancement by 85.0% decrease of water absorption and high concrete resistance to seawater effects by 15% increase in mechanical properties when SP was used. As a reason of using PP fibers, the mechanical properties of RA concrete enhanced so much especially tensile strength by 35.0%
