What are the Factors Affecting Concrete Pumpability? - The

Lightweight aggregate is porous and absorbs a significant amount of water in the concrete under pumping pressure. Eventually, pipeline blockage will occur. In addition, after the removal of pump pressure, the absorbed water comes out of the aggregate and leads to bleeding, especially during concrete slab placement.

Lightweight concrete

Pumping lightweight concrete can be achieved, but care needs to be taken so that the concrete mix doesn't separate. For pumpable mixes it is usual to use a natural sand, i.e. not to have a lightweight aggregate for the fine portion of the mix and to have a high workability so that increased pump friction and blockage is avoided.

Portable Concrete Pump - Small Concrete Pumping Machine

The concrete pump conveys wet concrete pumps through pipelines and the length of pipelines, power of the engine, rotating peed, the pressure of the pump all have an impact of the conveying distance. For portable concrete pumps, they can reach 120-180 meters vertically, and 300 – 600 meters horizontally.
