Ready-mix concrete - Wikipedia

Ready-Mix Concrete is concrete that is manufactured in a batch plant, according to a set engineered mix design. Ready-mix concrete is normally delivered in two ways. First is the barrel truck or in–transit mixers. This type of truck delivers concrete in a plastic state to the site. Second is the volumetric concrete mixer. must be accounted for by the engineers and finishers  Missing: anchors ‎| Must include: anchors

Soil Mix Walls - Deep Excavation Design and Construction

Mechanical soil mixing is performed using single or multiple shafts of augers and mixing paddles. The auger is slowly rotated into the ground, typically at 10-20 rpm, and advanced at 2 to 5 ft (0.5 to 1.5 m) per minute. Unreinforced soil mix walls are typically used as hyrdaulic barriers.
