For larger jobs such a culvert ballast. Crushed stone #8 – Sizes from 3/8″ to 1/2″. For concrete and asphalt mix. Crushed stone #3 -Sizes from 1/2″ to 2″.
Shotcrete, gunite (/ ˈ ɡ ʌ n aɪ t /), or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique, first used in 1914.: 7 It is typically reinforced by conventional steel rods, steel mesh, or fibers. Shotcrete is usually an all-inclusive term for both the wet-mix and dry-mix versions.
Both gravel and crushed stone are generally acceptable for making quality concrete (Photo 9), although gravel is usually preferred for exposed aggregate. The use of recycled concrete, crushed to proper-size concrete aggregate, has also demonstrated successful performance.
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named .
