Controlling the Quality of Construction Aggregates

Although construction aggregates are a manufactured product and usually represent the greatest quantity of any material used on a project, they are uniquely different from other materials. Because of economic considerations, aggregates must be provided from local resources. Thus, once an aggregate resource has been selected through proper geological and engineering evaluations, the inherent physical properties (specific gravity, abrasion loss, sulfate loss, and so on) and chemical properties of the aggregates produced are essentially fixed. There are a few deposits in which selective mining and special processing procedures are required to improve the properties and upgrade the quality of the aggregate. These special considerations are not considered in this paper; rather, it is limited primarily to control of aggregate
