MECHANISATION OF CONCRETING
CONCRETE MATERIALS AND QUALITY CONTROL
Taken from : Ambuja Technical Literature Series -14
MATERIALS FOR MECHANISED CONCRETING
The success of Mechanised Concreting is greatly dependent on the quality of concrete materials used and efficiency with which they are batched and
mixed at the production plant and transported as concrete to various sites. While it is absolutely necessary to have efficient and automatic equipment to
assure good quality concrete, it is equally important to have very dependable and consistent quality of concrete material supply at the production plant also.
This is an important factor which requires to be studied before the production plant is set up. It is important to identify the material suppliers well in advance so that they can deliver materials of desired quality and quantity.
Alternatively the production plant can be set up at the material source itself by the concrete producers. As aggregates (coarse and fine) are the maximum requirement weightwise it is often observed that plants are generally located at the aggregate source itself and the processed aggregates are transferred to the production plants by means of series of conveyors.
WHAT IS QUALITY ?
Traditionally quality is related to cost and performance. In concrete too 'quality' means high performance concrete and generally good quality concrete materials too are available at a higher cost.
In concrete, specifiers give their requirement for temperature, workability, pumpability, strength, durability and any other specific requirement. Hence,
quality is attained when the concrete supplied at site meets these specifications. As far as the material component of concrete production is concerned it is essential to do proper checks on the input material first and later proper check on the output material i.e. concrete.
