Pumping of Concrete: System, Working and Problems

Jul 10, 2020 · The pumping system of the concrete pump is an indispensable component of the concrete pump. In construction, it plays a very important role. As one of the main components, it, together with the hydraulic system and the electronic control system, constitute the three main structures of the concrete pump. So what are the characteristics of the

Treating and Recycling Concrete Process Water

May 29, 2010 · Characteristics of concrete process water Concrete process water is caustic and typically has a high pH value ranging between 11 and 12. It contains dissolved solids including sulfates and hydroxides from cement, oil and grease from equipment and derivatives from chemical admixtures.

Concrete - Columbia University

concrete, care should be taken to avoid segregation. For example, if dropped too far, the heavy or big aggregate particles can settle and lighter mix com-ponents, such as water, tend to rise. The concrete is conveyed from the mixing truck to its final desti-nation in dump buckets by cableways or cranes or by pumping through pipelines.

Pump Terms and Definitions

Total head (H) [H tx]– This is the measure of energy increase, per unit weight of liquid, imparted to the liquid by the pump, and is the difference between total discharge head and total suction head. This is the head normally specified for pumping applications because the complete characteristics of a system determine the total head required.

of the concrete substrate prior to repair, are also identified. Limitations and Further Research The scope of this project was large, and not all relevant aspects could be studied. The focus of this study was to identify relevant characteristics of some of the fundamental factors affecting the performance of concrete repairs and bonded overlays.

What Makes Concrete Pumpable?| Concrete Construction Magazine

Nov 01, 1991 · In a pump line, concrete moves in the form of a cylinder or slug separated from the pump line wall by a lubricating layer of water, cement, and fine sand. To keep moving through the line, the mix must be dense, cohesive, and have sufficient mortar. When concrete is pumped, if spaces or voids between aggregates are not filled with mortar, or if the mortar is too thin and runny, pump pressures
