Crushed rocks in grade no. 2 usually range from 1½ inches to 3 inches in diameter, so, depending on your supplier, may contain larger gravel stones that, like #1, are not easy to work with and will need to be moved as individual pieces. Uses of gravel #2 include the following:
The effects of aggregate type, size, and content on the behavior of normal and high-strength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed. The concrete mixtures incorporate either basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (:Y. in.), and
The biggest particle size may have a diameter of around 150 mm, and the smaller aggregate has a diameter of up to 5 to 10 microns. Aggregates are classified accordingly to particle size as follows: 5. Coarse Aggregates. The aggregate particle which retains on a 4.75 mm sieve is known as Coarse aggregate. 6.
Types of Aggregates ... These products are obtained by mining rock and breaking it down to a preferred size. In the case of manufactured sand, the product is obtained by crushing rock to the selected shape or texture, ensuring product and project specifications are met. Sources of crushed stone can be igneous, sedimentary, or metamorphic.
