Pouring Concrete: 8 Step Process (with Pictures
Oct 09, 2020 · A concrete truck may be able to pull up to the site and pour right into the forms. If the site is on the other side of the house or building, the truck may pour into wheel barrows or a concrete pump to get the wet concrete to the site. Concrete should not be placed when temperatures will drop below 20F.

Shotcrete - Wikipedia
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 1907 invented by Carl Akeley.: 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

Concrete Pumping - How to Pump Cement - Concrete Network
Line length: Concrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.

A Guide To Pouring Concrete in the Rain (updated 2021
Rain falling on top of freshly laid concrete can damage the surface and compromise a level and floated finish.Even worse, if too much extra water works its way into the concrete mix, this can result in weak concrete overall.. For this reason, it's important to never lay the concrete onto wet surfaces or trenches filled with water if there's a risk that the water may mix into the concrete.
