It is important to note that some gradations will have a range of stone sizes in that particular gradation. For example, a CA11 or CA7 (generally ¾") gradation may include individual stone sizes of 1" down to ½". When you're shopping for crushed stone, it's handy to know what the different grades mean.
The Different Types Of Aggregate. The categories of aggregates include gravel, sand, recycled concrete, slag, topsoil, ballast, Type 1 MOT, and geosynthetic aggregates (synthetic products commonly used in civil engineering projects used to stabilise terrain). Let's detail a few of them.
R5 aggregate is 9 to 18 inches, and R6 aggregate is 12 to 24 inches. R5 and R6 are the most common varieties of rip rap because they are the most versatile. Their heavy weight and mid-range size work well at reinforcing the edge of ponds, rivers, streams and lakes, as well as deterring pedestrian traffic.
Aggregate Gradation • Also known as "sieve analysis" • It is the distribution of particle sizes • "Well-graded" aggregates: particles evenly distributed among sieve sizes require less cement and water than "poorly graded" aggregates • Careful choice of aggregates provides for optimization of cement, water and admixtures

Opening sizes and mesh diameters for test sieves are often duplicated between these two standards, making it easier to select the proper sieve size for your material. The above table is a list of all available sieves in U.S. and metric sizes for both ASTM E11 and ISO 565/3310-1. Sieve mesh opening sizes range from 5in (125mm) down to #635 (20µm).
Aggregate Sizing Explained - Chaney Enterprises . best For example coarse aggregate has a standard grading requirement for each different size from #1 to #8.

sieve is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate." Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.). ASTM C 33 ("Standard Specifications for Concrete Aggre-
Jul 07, 2014· A coarse aggregate which has the sizes of particles mainly belonging to a single sieve size is known as single size aggregate. For example 20 mm single size aggregate mean an aggregate most of which passes 20 mm IS sieve and its major portion is retained on 10 mm IS sieve. All in Aggregate.
A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate is a nominal size of 3/8 to 0.094 inch. More specifically, a #57 aggregate is the combination of #5 and #7 aggregates ranging from 1 to 0.19 inch.

One such coarse aggregate is crushed burnt bricks obtained from the production of burnt bricks (Maher, 1987). 1.2 OBJECTIVES OF STUDY. The purpose of this research is to compare the compressive strength, flexural strength, and fracture energy of normal and high-strength concretes with different aggregate types, sizes, and contents.
Aggregate specifications have an allowable range of different stone sizes, expressed as a percentage of the total weight of sample. This gradation specification is reported on a table or chart (see example ). The below nominal maximum …
Middle-Grade Sizes. Size #57 is another of the more popular gravel sizes. This particular size of gravel ranges in diameter from 3/4th of an inch (1.9 centimeters) to 1 inch (2.54 centimeters) in diameter. This gravel is often used for paving walk or driveways, at it can be walked and driven on with relative ease.
In practice, there is no maximum size for aggregate. But usually the highest you'll want to go for structural applications is 40mm, unless you're heading a mass concreting project such as a dam. Then you can go up to 150mm. Fine Aggregate Fine aggregates are any aggregates less than 4.75mm in size per piece. This includes sand, silt and clay.
Aggregate gradation is of 4 types as explained below: 1.Well-Graded: An aggregate sample is said to be well-graded if it possesses all the required sizes in the required proportions. In other words, such a sample has a wide range of particle sizes present in the mix.
A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate is a nominal size of 3/8 to 0.094 inch. More specifically, a #57 aggregate is the combination of #5 and #7 aggregates ranging from 1 to 0.19 …
Generally, as the grade number goes up, the size of the stone goes down. #1 – The # 1 crushed stone grade is the largest of the crushed stone grades and includes stone between 2-4 inches long. This material is great for larger jobs or for filling in larger holes. #3 – This size of the stone ranges from 1/2 to 2 inches long.

Based on the grain size, the aggregates are classified into two types. Fine Aggregate. Coarse Aggregate. The fine aggregates are used in concrete as a filler material to fill the voids. The coarse aggregates are used in concrete to develop the strength of the element. The difference between the fine & coarse aggregate are listed below.
