Uses of Destructed Concrete in Establishing Simple Houses for Displaced People
The need in the construction sector continues to demand for destructed concrete, especially in times of war, and for low-income displaced people. Lack of natural resources to obtain scrap, is one of the biggest problems facing the concrete production. The environmental pollution is as a result of the building destruction. Waste collects and poses an environmental risk to human health, organisms and nature. Nowadays, great interest has been developed for the reuse of recycled destructed concrete aggregates which represent a very large proportion of the volume of destructive concrete resulting from the wars and the destructions in the Middle East. Low cost and acceptable quality, are also essential for low-income housing. The main goal of this research is to obtain concrete at low cost for this purpose. The experimental out comes indicated that the cubic compressive strength measured for the test specimens; the concrete compression was found to increase as the rate of replacement of the destructed concrete was reduced. The conventional concrete of 25 MPa specific strength at 28 days was used for comparison purposes. The importance of this study is to construct simple houses from recycled destructed concrete for emigrant low income displaced people, after the war and earthquake stopped. Also to study the efficiency of produced concrete as a replaced aggregate through evaluation of some physical and behavioral characteristics.
