25/2/2019 · After water, concrete is the most widely used substance on Earth. If the cement industry were a country, it would be the third largest carbon dioxide emitter in the world with up to 2.8bn tonnes
A concrete pump is a machine used for transferring liquid concrete by pumping.There are two types of concrete pumps. The first type of concrete pump is attached to a truck or longer units are on semi-trailers. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately.

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is
Concrete blocks are made in various weights and sizes and they are used to make about two-thirds of masonry walls in the US. Engineers have designed kinds of concrete for certain uses. Air-entrained concrete is good in harsh weather and is used for roads and airport runways.
