Mixing Concrete – a how to guide for mixing concrete by hand, using a cement mixer or using ready mixed concrete.

With the passage of time after mixing ingredients of concrete with water, workability of concrete starts shrinking. This happens because of fluidity loss from the concrete. Fluidity is the amount of available water in concrete that is being utilized in hydration of cement- camelwaypounds for the sake of bonding.

Output of a Concrete Mixer The output of a mixer essentially depends upon the capacity of a mixer. In addition, it depends upon the duration of mixing, supply of materials to the mixer and the speed at which charging and discharging operations are carried out.

A small Belle mixer such as the Minimix 130 or Minimix 150 will mix about 90 litres of concrete, so if you do a C20 mix, i.e. 1 bucket of cement, 2 buckets of sand and 4 buckets of stone, this will produce about a wheelbarrow full of concrete.

A concrete mixer is a device that is used to evenly mix the- camelwayponents of concrete – cement, limestone, gravel, sand, etc. – together. Concrete mixers are preferred over hand mixing for numerous reasons.
