Wadi natural aggregates in Western Saudi Arabia for use in Concrete
Abstract The engineering properties (physical and mechanical) of Wadi Al-Yamanyah natural aggregate were determined. In addition, correlations between these properties have been made. This Wadi is located in the central part of the western province of Saudi Arabia between Makkah and Taif. The aggregate along the Wadi was studied and five major rock units were identified namely granite, granodiorite, gneiss amphibole schist and andesite. These rocks were classified into three aggregate groups: basalt, granite and schist. Ninety aggregate samples were carefully collected and tested. The results of overall aggregate properties pointed out that Wadi Al-Yamanyah natural mixed aggregate is within the international and local specification limits and it is suitable for use in concrete. The estimated volume of natural aggregate in the Wadi is about 2 million $ m^{3} $. The engineering properties of individual aggregate groups were also determined. Basalt and schist groups, which represent about 65% of the Wadi natural aggregate, were of higher quality and low degree of alterations than the granite group. Direct and inverse relationships were found between some physical and mechanical properties for mixed natural aggregate of Wadi Al-Yamanyah with the exception of elongation index ($ I_{E} $). It is recommended to use the derived equations, representing the best fit between the aggregate properties, with care and for rough estimation only.
