Crushed Stone Grades. The following list gives a rundown of crushed stone grades and their best uses. While there may be slight variances in the naming convention of crushed stone the following are the most common names and sizes: Crushed stone #5 – Sizes are from 1″ down to fine particles. For road and paver base.
The effects of aggregate type, size, and content on the behavior of normal and highstrength 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
