Coarse Aggregate. Coarse aggregates are retained on a 4.75mm sieve and typically include materials such as gravel, cobble, and boulders. The choice of maximum aggregate size depends on specific conditions, with 40mm size used for normal strength concrete and 20mm for high-strength applications. Applications of Coarse Aggregates

All-in aggregate, also known as Ballast, is a mixture of material from various sizes from a pit, crushing plant or river bed. This type of aggregate is commonly used for repairing small cracks and pavement foundations. The basis for these sizing standards originates from ASTM C 33, "Standard Specification for Concrete Aggregates."
Maximum Aggregate Size. Maximum aggregate size can affect HMA, PCC and base/subbase courses in several ways. In HMA, instability may result from excessively small maximum sizes; and poor workability and/or …
Source: ASTM Standard C33/C33M The second column in the table shows the aggregate size range that is always decided prior to use. For example, if we are to prepare a concrete mix using an aggregate sample that contains a maximum particle size of 63mm and a minimum particle size of 37.5mm, we'll look through the second row and …
• Larger aggregate diameters reduce the quantity of cement and water needed. 20 mm aggregate . Common aggregates • Crushed Stone and Manufactured Sand. Stone is quarried, crushed and ground to produce a variety of sizes of aggregate to fit both 'coarse' and 'fine' specifications. • Gravel
Aggregate is classified into two general sizes: coarse grained and fine grained. Coarse aggregate is rock retained on a 3/8-inch (#4 U.S. sieve). Fine aggregates pass the 3/8-inch sieve and are retained on a #200 U.S. sieve. 6. Fine Aggregate. Fine aggregate consists of natural sand, manufactured sand, or a combination.

Or in the other, when the least dimension of aggregate is less than the 60% of its mean dimension then it is said to be flaky aggregate. Elongated Aggregates When the length of aggregate is larger than the other two dimensions then it is called elongated aggregate or the length of aggregate is greater than 180% of its mean dimension.
Quality Counts. Make sure that your concrete producer purchases good-quality aggregate as verified by regular aggregate test results in compliance with ASTM C 33, "Standard Specifications for Concrete Aggregates." A history of good performance of a local aggregate also provides an indication of how well the material performs in service.
