Characteristics of Aggregates - Civil Snapshot
The characteristics of the aggregates influence the properties of the concrete. Weak, friable, or laminated aggregate particles are undesirable. Aggregates containing natural shale or shale like particles, soft and porous particles, and certain types of chert should be especially avoided since they have poor resistance to weathering.
