Abstract
Pakistan has vast potential of concrete aggregates due to having numerous mountainous ranges.
However, the properties of these aggregates are yet to be explored as scant research has been carried
out in this area. In this study, an experimental approach was adopted to compare the engineering
properties of widely used coarse aggregates in Pakistan. Aggregate samples were gathered from four
various quarries in accordance with ASTM sampling procedure and their physical as well as
mechanical properties were evaluated through laboratory testing according to ASTM and BS
standards. Tests were performed on Margalla, Sargodha, Barnalla and Mangla crushes. Different
concrete specimens were also prepared using the above mentioned aggregates and tested for their
mechanical properties (compressive, tensile and flexural strengths). Test results revealed that the
aggregates from evaluated quarries are suitable to be used in concrete. Each sample of aggregates
have different characteristics which is very important keeping in view the type of construction,
economy and its environment. It was observed that Margalla aggregates resulted in better concrete
mechanical properties, while Sargodha aggregates showed improved physical characteristics
