Pumps for Wet-Mix Shotcreting| Concrete Construction

The number of construction projects using wet-mix instead of dry-mix shotcrete continues to grow, primarily because wet-mix shotcreting can achieve a higher production rate. Contractors using this concrete placing method have a number of pump options. But what’s the best pump type to own or rent? The answer depends mainly on the volume of concrete to be placed.Author: Author/Ward-R-Malisch

Dry Mix Process and Wet Mix Process for Shotcrete

Dry mix process and wet mix process are the two methods of shotcrete construction which are based on the time at which the water is added to the mortar or Shotcrete is a type of concrete or mortar mix that is shot onto a surface at high-speed. The shotcrete process can be performed in two ways, either using a dry mix or by means of a wet mix.

Shotcrete – Wikipedia

pump concrete made with 3⁄ 4-minus aggregate, and can easily handle wet-mix shotcrete, which may contain smaller aggregates. Most models also have watertight valves to keep the mix liquid. “Shotcreting with a mechanical ball-valve pump will take its toll on the equipment, resulting in higher than normal maintenance and repair

Pumps forWet-Mix Shotcreting Tips for choosing the best equipment for the job For wet-mix shotcreting, the aggregate, cement, and water are thoroughly mixed before they’re discharged into the hopper of the delivery equipment. The nozzleman adds compressed air at the nozzle, producing discharge speeds of 150 to 250 feet per second.

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.

concrete pump thinking that it will be suitable for several different types of wet-mix applications. Most concrete pump outputs range from 20 to 50 yd 3/h (15 to 38 m /h). Such pumps are suitable for medium- to high-volume output of wet-mix shotcrete. However, for repair jobs using wet-mix shotcrete, lower output pumps are required; and because …
