| 摘要： | Data in this handbook are based upon a comuter model of dry packed, monosized particles adapted from the therories developed by Aims (1967) and Toufar (1967). The model has been demonstrated to adequately describe similar dry packing of powders with varying size distributions in terms of the Rosin-Rammler D' coefficient. The model has been successfully applied to the system cement/fine aggregate/coarse aggregate and has modeled Cement and Concrete Assoication, Portland Cement Association and Pennsylvania Department of Transportation recommended concrete formulations. The results theoretically support the location of recommended concrete formulations in a region of ternary particle mixing which possess the maximum dry packing density. The handbook consists of graphical representation of selected formulation variables and tables detailing packing densities for mix proportioning. |
