Evaluation of engineering properties of scoria in central Harrat Rahat, Saudi Arabia
Abstract Although black scoria deposits occur extensively in western Saudi Arabia, there has been little work undertaken on its engineering characteristics as a light-weight aggregate which can be used in concrete for structural, masonry and insulating purposes. In an attempt to remedy this, central Harrat Rahat was selected for an engineering evaluation of scoria deposits in the vicinity of major cities where it may provide an easily accessible resource for natural aggregate. The petrography of the scoria and the deleterious material content were found to be acceptable by ASTM standards, but grading analyses indicated it would need to be processed before use. The other physical properties of the scoria such as bulk density, specific gravity and absorption indicated that samples from Jabal Halat Ash Shaykh quarry gave acceptable results. The porosity of the scoria is relatively high and some of the pore spaces are not interconnected. The material is pozzolanically active and can be also used as an additive to Portland cement.
