PROPERTIES OF AGGREGATES FOR CONCRETECivilBlog

Sep 03 2017 · For example the density of concrete is determined by the density of the aggregate. Soft porous aggregates can result in weak concrete with low wear resistance while using hard aggregates can make strong concrete with a high resistance to abrasion. Aggregates are of two basic types Coarse crushed rock gravel or screenings.

3 Aggregate Properties

The hardness of the minerals that make up the aggregate particles and the firmness with which the individual grains are cemented or interlocked control the resistance of the aggregate to abrasion and degradation. Soft aggregate particles are composed of minerals with a low degree of hardness. Weak particles have poor cementation.
