Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows. Cement:
Transporting the concrete mix is defined as the transferring of concrete from the mixing plant to the construction site. The main objective in transporting concrete is to ensure that the water-cement ratio, slump or consistency, air content, and homogeneity are not modified from their intended states.
The process flow for stationary concrete batch plant will start from feeding of aggregates to the feeder bins. Process of concrete mixing plants end at the output of fresh concrete from the mixer. Modern batch mix plant consists of components like feeder bins, conveyor belts or skip hoist, weigh conveyors, weigh hoppers, screw conveyors, cement silos, mixing unit and control panel.
To make 1:1:2 ratio concrete mix according to volume batching, one should take one bag of cement (35 liters) , 1 gauge box of fine aggregate (35 liters) and 2 gauge boxes of fine aggregate (70 liters). If the water-cement ratio is 0.5, then half of the volume of cement which is 25 liters of water should be taken.
Compaction of concrete is one of the important site operations that together enable the fresh concrete to reach its potential design strength, density and low permeability. Properly carried out it ensures that concrete fully surrounds and protects the reinforcement, tendons and cast-in inserts.

Batching. Mixing. Transporting and Handling. In this presentation we will be discussing the batching, mixing, transporting, and handling concrete. The discussion will begin with ordering concrete and the difference between performance and prescriptive specifications.
Prior to placement of concrete, workability of the mix is checked by slump-cone test, in addition to visual test for consistency and homogeneity. To keep the concrete temperature under control (maximum permissible temperature being 32 degree C), chiller systems are provided in the batching plant to cool the water before dispatching into the mixer.
Apr 10, 2014 · What Is Volume Batching of Concrete? Batching of concrete means measuring different ingredients of concrete (i.e. cement, sand, coarse aggregate and water) before mixing it. When this measurement is done on the basis of volume, we call it Volume Batching. Below are mentioned some of important points to remember before adopting volume batching method in …

A concrete plant or batching plant is very important equipment for the concrete construction. With the help of concrete batching plant, concrete used for the construction is produced by proper mixing of all the ingredients like sand, gravel, water and cement and then transported to concrete construction site ready to be poured for use.
This site will define, analyze, and demonstrate the importance of each in the overall process of placing concrete. 2.0 Batching and Mixing Concrete. Mixing concrete is simply defined as the "complete blending of the materials which are required for the production of a homogeneous concrete" (Young, 267).
is quite important since the quality of all ingredients, mixing time, mixing procedure, and curing can greatly influence the quality of the hardened. Concrete is cured in a wet environment in order to avoid loss of moisture through evaporation. The chemical reaction of water and Portland cement binds the aggregate particles in concrete.
