Tool-Center-Point Control of a Concrete Pump Using

Concrete Pump Hazards & Safety - Concrete Network

The primary concern when utilizing a pump truck during a pumped concrete pour is safely positioning the truck where the boom can reach the concrete placement site. The key word here is "safely." Improperly positioned, a pump truck can cause death or serious injury, making a nightmare out of what may have appeared to be a standard, "every day" pour.

Using Concrete Pumps for Shotcreting| Concrete

Nov 01, 1995 · In wet shotcreting, a concrete pump delivers ready mixed concrete with a predetermined water-cement ratio to the shooting nozzle at a rate of approximately 3 feet per second. Compressed air traveling at 150 to 200 feet per second is then introduced at the nozzle, a precise dose of fluid accelerator is usually injected into the propellant air. The mix of air and accelerating agent breaks up the

Concrete placement can be accomplished by either a tremie supported and maneuvered by a crane or the discharge end of a concrete pump. Frequently contractors will use multiple-tremie systems with each hopper supported by bracing or walkways in the cofferdam.
