摘要: Abstract A key theory in concrete mix design is maximizing aggregate packing density (PD) of mixture. Different methods have been presented by researchers to estimate PD One such method computer simulation that has become increasingly common over the last decade; however, it usually a time-consuming procedure. In current study, based on proposed for estimating PD. this method, aggregates with specific shapes, grading and PDs are substituted monosized spherical aggregates. An equation also determining diameter equivalent The coefficient friction between determined way will equal actual used simulate laboratory experiments conducted present authors other researchers. Comparisons reveal high accuracy simple predicting mixtures.
