Estimation of the Pumping Pressure from Concrete …

A new method is proposed to estimate pumping pressure based on concrete composition without experimental measurements. Previous studies show that the pumping pressure depends on the interface friction between concrete and the wall of the pumping pipes. This friction is determined by the thickness and the rheology of the boundary layer formed at the interface. The latter is mainly formed …

Boom stability control: A new solution to reduce …

In operation, as the boom is maneuvering and pumping concrete, the tip can oscillate 4 to 6 feet (1.5 to 2 meters). To manage the oscillation, additional workers are typically required to hold the boom tip hose, and concrete pumping speed may also be decreased.

Making Concrete Pumpable| Concrete Construction …

2020/1/28· He notes that water content is often higher in lightweight concrete than in standard-weight concrete and that sufficient aggregate moisture is critical in successfully pumping lightweight concrete. The critical factor is to make sure the lightweight aggregate is saturated surface-dry as it goes in so that it will not absorb water from the mix, especially under the pressure of pumping.

Concrete Pump Blockage - Causes & Clearing - The …

Another thing to look for are bends that are too short, too sharp, or too numerous, all of which increase concrete pumping pressure. Variations of pipeline diameter, such as when a larger diameter hose is coupled with a smaller one, may cause blockages or rock jams because the concrete can''t flow as quickly through the smaller diameter pipeline.
