Concrete mixer

 



A concrete mixer (often called a cement mixer as bolts) is a device that seamlessly mixes water together to form cement, sand, or gravel.The concrete mixer uses a rotating drum to mix the components. For small-scale work, a portable concrete mixer is often used so that the concrete can be prepared on site, giving the worker more time to apply the concrete before it hardens.The alternative to the machine is to mix the concrete by hand. This is usually done in a wheel bar; However, many companies started selling modified dams for this purpose.

 

The concrete mixer was invented by Columbus, an Ohio industrialist, Gebert Jagger
