The Effect of Aggregate Properties on Concrete

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.

Strength - Penn State College of Engineering

Concrete mixtures containing rough textured or crushed aggregate would show somewhat higher strength at early ages than corresponding concrete containing smooth or naturally weathered aggregate of similar mineralogy. A stronger physical bond between the aggregate and the hydrated cement paste is assumed to be responsible for this.

METHOD OF TEST FOR RELATIVE COMPACTION OF …

This test method describes the procedure used to determine the relative compaction of untreated and treated soils and aggregates. Relative compaction in this method is defined as the ratio of the in-place, wet density of a soil or aggregate to the test maximum wet density of the same soil or aggregate when compacted by a specific test method.

Effect of Aggregates on the Properties of Concrete ...

Thus rougher the surface as that of a crushed stone, better the bond. Secondly bond is also affected by other physical and chemical properties of aggregate. The determination of bond strength of aggregate is difficult and no accepted test exists. It is judged by the surface of a crushed concrete.

Infact this is not so with crushed aggregate as in mechanical crushing there are chances of attached crack and week fragments in the aggregate which may affect the strength of concrete. 6. Unwashed crushed aggregate surfaces are generally coated with crusher dust, therefore, the rough surface bond benefit of crushed aggregate is not fully utilized.
