Naturally occurring concrete aggregates are a mixture of rocks and minerals (see Table 5-1). A mineral is a natu- The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following section: Grading.
Aggregates comprise as much as 60% to 80% of a typical concrete mix, so they must be properly selected to be durable, blended for optimum efficiency, and properly controlled to produce consistent concrete strength, workability, finishability, and
