Abstract
Generally, the properties of aggregate greatly affect the physical and mechanical properties of concrete. Flat and elongated particles in coarse aggregates, for some construction uses, may interfere with consolidation and be difficult to place. In this study, an experiment to evaluate properties of flat and elongated particles as coarse aggregate in concrete was conducted. The experiments include slump test, air content test and compressive strength test. The test result of slump and change of slump was rapidly decreased by percentage of flat and elongated particles. But it had not a trend by increasing percentage of flat and elongated particles. Compressive strength of hardened concrete does not make any differences in comparison.
