HIGH PRESSURE CONCRETE PUMPS ScienceDirect Related Information

High-Pressure Pump - an overview | ScienceDirect Topics

High-pressure pumps producing auxiliary high-velocity jets may be employed to improve wheel-cleaning action as illustrated in Figure 8.7. Pump pressures may be up to 100 bar (1500 lbf/in. 2 ). Whereas the primary jet aims to direct the fluid into the grinding contact, the auxiliary cleaning jet may be directed to impinge on the wheel acting against the wheel speed.

Concrete Pumps - Types and Selection - The Constructor

Check high rated concrete pumps and their respective customer reviews. The concrete pumping process is performed under high pressure. A good concrete pump must be able to withstand this long-term pressure. If the quality of the concrete pump is below average, it results in the breakdown and loss for the construction projects 2.

Effect of W/C Ratio on Durability and Porosity in Cement

Water is often added to concrete placing for easy workability and finishability in construction site. The additional mixing water can help easy mixing and workability but causes increased porosity, which yields degradation of durability and structural performances. In this paper, cement mortar samples with 0.45 of W/C (water to cement) ratio are prepared for control case and durability
