Abstract
Abstract The paper describes a basic analytical method for calculating the surface area of fine aggregate particles (sands and fillers). Equations were derived for direct determination of the specific surface using data of actual size distribution, fineness, and shape properties of the particles. Practical calculation examples are given and compared with other conventional methods and with experimental determination of the surface area. In general, the method is flexible and affords a desirable degree of accuracy according to a proper partitioning of the size range into fractions. Results of the calculated surface areas were very close to values obtained experimentally. This indicates the advantages of the suggested method over some other useful methods for surface area calculations. The suggested method is basic and general and can be applied to any technology where the surface area of fine particles is an important factor.
