Concrete Mixing

Concrete Mixing

The purpose of proper mixing is to ensure that mass should become homogeneous, uniform in color and uniform in consistency.

There are two types of mixing that are adopted in the field i.e. Hand Mixing and Machine Mixing

(a) Hand Mixing It is done manually and thus inferior to machine mixing as it can’t give homogeneous and uniform concrete.

(b) Machine Mixing It is an efficient and economical way of mixing in which homogeneous and uniform mixing can be ensured. It can further be divided into two categories as given below:

(i)Batch Mixing – The mixing of concrete is done in batches.

(ii)Continuous Mixing – The mixing is done continuously till the plant is working. All the ingredients are fed through screw feeder in a continuous manner. It is used in large works such as dams and bridges.
