Concrete mix construction using local materials in Karak and Tafila area

Concrete construction is much common compared to steel or timber in Jordan. Locally, aggregates are available in two different types crushed and wadi (valley) rounded stones. The valley stone is not highly used as crushed stone is mined on surface in known sites (Karak and Tafila). Also fine materials are mined for other construction jobs such as plastering, tiling, and roofing surface (in Karak). The current research aims to introduce the use of round aggregates in concrete compared to crushed aggregate on concrete grades of 15, 20, and 25 Mpa. The Results on crushed and round aggregates are beneficial to have the variety in resources in aggregate and properties of concrete. The new employment of rounded valley aggregate is part of the sustainability in construction process and resources which is required essentially and has less dust evolution on environment, in addition to the opportunity in having new jobs for local people and improvement on their socio-economic levels of living.
