The desirable and undesirable properties of aggregates for concrete have been thoroughly reviewed in a number of texts on concrete technology (Orchard 1976; American Society for Testing and Materials 1978; Murdock, Brook & Dewar 1997; Fookes 1980; Neville 1995). In practice, difficulties are frequently encountered in translating these ...
consists of three fourths of the concrete mix. In addition to the concrete mix materials are composed of water, cement and additives, if necessary. Because the total quantity of aggregate in a concrete mixture is large, the strength and durability of a concrete depends on the characteristics of aggregate itself (Jeffery, 2010).
