Methods for Mixing of Concrete Their Procedure & Precautions!
Ready mix concrete is particularly useful on congested sites or in road construction where there is little space or no space available for a mixing plant or for storage of aggregates. In this method, quality control of concrete is easy as the batching and mixing of concrete is done at the mechanized central batching plant. This method of mixing is very useful for several places i.e. in congested area, at night concreting work, at large construction site etc.
Ready Mix Concrete Batching, Mixing, Transporting, and Handling
The concrete mixer can mix up to 9m 3. It can have tilting or non-tilting drum, open top revolving blade or paddle. Typical complete mixing times of this machine is minimum of 1 min. for up to 1 m 3 or less mixer capacity plus 15 seconds for each additional m 3 or fraction thereof.
Hand Mixing of Concrete -Procedure and Precautions
Concrete is mixed by any two methods, based on requirement as per quality and quantity of concrete required. Normally for mass concrete, where good quality of concrete is required, mechanical mixer is used. Mixing by hand is employed only to specific cases where quality control is not of much importance and quantity of concrete required is less. Stone aggregate is washed with water to remove dirt, dust or any other foreign material before mixing.
Mixing Concrete by hand, cement mixer or using ready mix
Mixing Concrete . When it comes to mixing concrete, there are three options to choose from: Mix by hand - where less than ¼m³ of concrete is needed, it can be mixed by hand by a reasonably fit person.

mixing time of one minute plus 15 seconds for every cubic meter (yard), unless mixer performance tests demonstrate that shorter periods are acceptable and will provide a uniform concrete mixture. Short mixing times can result in nonhomogenous mixtures, poor distribution of air voids (resulting in poor frost resistance), poor
