摘要：

The implementation of a step-by-step concrete mixture design procedure to determine an optimized aggregate gradation is described. The procedure uses both the modified coarseness factor and percent retained charts to establish an optimal blend of user-selected aggregates, criteria that are usually not implemented simultaneously. The design process is iterative and depends on the gradations of available aggregates, the cementitious material content of the concrete mixture, and the maximum aggregate size. The procedure can be implemented using a spreadsheet and, unlike traditional approaches, is capable of blending aggregates with significantly different specific gravities.
