Concrete Pumps - Types and Selection - The Constructor

The concrete pumping to different heights like in the construction of high-rise building can be performed by boom concrete pumps. Boom concrete pumps allow the pipeline to reach along, upwards and below. Hence tight spots can be cast by these pumps. Obstacles during the concrete casting path can be easily overcome by such pumps. 2. Line

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined.
