What are the Different Types of Gravel? (with pictures)
Gravel is often used as an aggregate in concrete. Manmade gravel, like crushed rock and crushed stone, can come in a variety of sizes. When making these types of gravel, natural stone is mechanically broken up and sifted through differentsized mesh screens.
Aggregate Size
Aggregate size fractionation is based on the premises that: (1) organic matter binds mineral particles together. Aggregate size fractionation can then be used to separate the organic matter responsible for aggregation (Puget et al., 1995) and (2) aggregates of different sizes correspond to different microbial habitats and provide contrasting conditions for decomposition (Beare et al., 1994 ...
The Effect of Maximum Coarse Aggregate Size on the ...
aggregate sizes of 10 mm and 20 mm conducted by Su and Cheng (2013) concluded that normal strength concrete with compressive strength lower than 60 MPa, larger maximum aggregate sizes would yield a lower compressive strength, but for high strength concrete with compressive strength greater than 80 MPa the effect of aggregate size was insignificant.

Based on the size of the particles of aggregates, following classifiion is made: Fine aggregate: aggregate particles smaller than 5 mm (3/16 in.) or ASTM sieve size Coarse aggregate: aggregate particles equal to or larger than 5 mm (3/16 in.) or ASTM sieve size 2) Petrographic ( Geological) Classifiion
Aggregates
01/03/2017 · Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydrauliccement concrete, or iron blastfurnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the mm (No. 4) sieve, are called coarse aggregates. Those particles passing the mm (3/8 inch)

Aggregate size| Concrete Construction Magazine
The larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower waterratio than the smaller sizes. 3. The advantage of small aggregate in the waterratio strength relationship may or may not be sufficient to offset the effects of its higher mixing water demand.
