Concrete is the most familiar building element. The densest and strongest
concrete is that in which cement paste fills the voids with the sand and the resulting mortar fills the voids in the coarse aggregate. Every grain of sand should be entirely coated with cement. Before the invention of the mixing machine, the entire mixing process used to be done by hand, shovel, shallow box. But now due to the high demand in construction, different types of mechanical procedures and
machines are used for mixing.
As technology has changed, the basic
mixer design has also evolved.
Concrete mixers can be divided into general
mixers and forced
mixers. Nowadays,
twin shaft mixers, vertical axis
mixers, and drum
mixers are the most commonly used
mixing machines.
The followings are the types of
concrete mixing
machines.
