  • Batching, Mixing, Transporting, and Handling Concrete

    BATCHING Batching is the process of measuring concrete mix ingre-dients by either mass or volume and introducing them into the mixer. To produce concrete of uniform quality, the ingredients must be measured accurately for each batch. Most specifications require that batching be done by mass rather than by volume (ASTM C 94 or AASHTO M 157).

    03. Weigh Batching of Concrete: Weigh batching of concrete is accomplished with the use of a weigh batch or the weighing system on the batching plant. On big projects, automatic batching plants are set up to facilitate optimizing quality and uniformity. Water is very vital material and therefore, maximum water should be used for batching.

    Jun 26, 2014 · For the air-entraining admixture (AEA) dosage of 1.05 fl oz/cwt, only 5.92 fluid ounces are required per yard, or about 12 fluid ounces (one soft-drink can) for this 2-yard load. This is only 0.75 pounds of AEA for the almost 7,500 pounds of concrete in this batch, for a weight ratio of 0.01%.

    Apr 10, 2014 · Step-1-Batching of cement. Cement is always measured by weight. Mostly it is used in terms of bags. One bag of cement weighs 50 kg and has a volume of 35 litres (or, 0.035m 3 ). Cement should not be batched by volume because its weight per unit volume varies according to the way the container is filled.

    May 29, 2010 · Here is another important note: Most mixers' batch capacities are actually about 67 percent (or two-thirds) their total volume. Therefore, if a plant needs to batch 1 yard of concrete, the mixer's total volume would need to be 1.5 cubic yards. It is important to know how a mixer is rated, either by batch volume or total volume.
