Mobile volumetric mixers batch concrete by volume and continuously mix concrete as the dry ingredients, water, and admixtures are fed into a mixing trough that is typically an auger system. The concrete must conform to ASTM C685 (AASHTO M 241).
Current research focuses on assessing productivity, cost, and delays for concrete batch plant (CBP) operations using Artificial Neural Network (ANN) methodology. Data were collected to assess cycle time, delays, cost of delays, cost of delivery, productivity, and price/m3 for the CBP.

Mixing and Transporting Concrete 1.0 Introduction The successful placement of concrete is dependent upon careful mixing, the proper equipment, and adequate transportation. This site will define, analyze, and demonstrate the importance of each in the overall process
18/3/2017 · It is important to compact the concrete fully because: Air voids reduce the strength of the concrete. For every 1% of entrapped air, the strength falls by somewhere between 5 and 7%. This means that concrete containing a mere 5% air voids due to incomplete compaction can lose as much as one third of its strength.
Check to ensure accuracy and dependable operati on of the proposed equipment and methods prior to the start of concreting operations and after ma king any changes in the location or arrangement of the batching plant. Plant calibration is the responsibility of the Producer/Contractor.
