A concrete mixer is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. A typical concrete mixer uses a revolving drum to mix the components. For smaller volume works, portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to use the concrete before it hardens. An alternative to a machine is mixing concrete by hand. This is usually done in a wheelbarrow; however, sever

instance, the mixer typically specified to batch UHPC is a high shear/energy mixer (e.g. pan). Currently, little information is known as to whether a beneficial or negative impact may be experienced in concrete properties (e.g. flow, strength, MOE) when a lower shear/energy mixer (e.g. drum/ready-mix truck) is used.
Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
A concrete mixer is a device that homogeneously combines concrete, aggregate such as sand or gravel, and water to form concrete - a powered device that mixes concrete with water and aggregate, such as sand or pea gravel, to make concrete.
