Influence of Aggregate on Concrete Strength. The rougher the surface of the aggregate and the greater the area in contact with the cement paste the stronger a concrete will be. Rounded particles result in lower strength than crushed aggregates. Larger size aggregates lead to lower strength in concrete.
angle 0 a crushing energy is applied to the soil aggregate between the plates. Part of Fj must be used to overcome gravitational forces generated by the aggregate and plate mass in addition to crushing the aggregate. In contrast the force normal to the vertical plate on pivot b F2 reacts only to force caused by crushing action on the aggregate.

Concrete and aggregate used in your construction projects has to meet strict regulations and quality standards. As these standards are often compulsory concrete and aggregate testing by an independent thirdparty is necessary to help assure compliance.
Each crusher is designed to work with a certain maximum size of raw material and often delivers its output to a screening machine which sorts and directs the product for further processing. Typically crushing stages are followed by milling stages if the materials need to be further reduced.
Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing degradation and disintegration Therefore an L.A. abrasion loss value of 40 indicates that 40% of the original
