14. AGGREGATES - cvut.cz

14.5 Determination of Particle Shape of Coarse Aggregates . Particle shape and surface texture are important for proper compaction, deformation resistance and workability. Rounded particles create less particle-to-particle interlock than angular particles and thus provide better workability and easier compaction. Flat or elongated particles tend to impede compaction or break during compaction ...

A good and efficient granular constituents should contain all the above mentioned shape of aggregates to fill the space between other shapes of aggregates. However, if you are asking about the ratio of each of the above aggregates, I should say that angular aggregates must constitute the majority of the aggregates for a more suitable construction.

Aggregate | Definition of Aggregate by Merriam-Webster

"Aggregate" is commonly employed in the phrase "in the aggregate," which means "considered as a whole" (as in the sentence "In the aggregate, the student's various achievements were sufficiently impressive to merit a scholarship"). "Aggregate" also has some specialized senses. For example, it is used for a mass of minerals formed into a rock and for a material, such as sand or gravel, used to ...

Aggregate in Concrete - The Concrete Network

Contractors placing decorative exposed-aggregate concrete, where appearance is a prime concern, should pay special attention to the aggregate shape, texture, color, and overall appearance to yield the best looking final product (Photo 8). When placing architectural concrete, you should test trial mixes and place mock-ups to ensure that all parties are satisfied with the materials selected.
