Learn MoreMethods of Batching Concrete 1. Volume Batching. In volume batching, materials are measured on the basis of volume. It is less precise method of batching; Measurement boxes or gauge boxes of known volume are used to measure materials. Cement is taken in the form of bags, where volume of one bag of cement (50 kg) is taken as 35 liters.

Learn MoreVolume batching is not accurate because the materials like cement, sand, aggregate have different densities and weight differs when contained in same box. Volume batching is approximation process. For accurate one use weigh batching.

Learn MoreThe choice of batching method depends upon size of job, production rate and standards of batching performance. Traditionally batching is done by volume. Batching accuracy is important. It is however recommended to do weigh batching rather than volume batching. Volume batching may be allowed only where weigh batching is not practical.

Learn MoreThe process of measurement of ingredients (cement, fine aggregate, coarse aggregate and water) for making concrete is called batching. Batching is done in two ways. 1) Volume batching. 2) Weigh batching. Volume batching: This method is generally adopted for small jobs. Gauge boxes are used for measuring the fine and coarse aggregate.

Learn MoreVolume-Batching of Aggregates: In volume batching, materials are measured by volume (in liters or cubic meters). For measuring the ingredients of concrete by volume a typical gauge box is used as shown in Figure. These gauge boxes are available in different sizes particularly of 35 litres (i.e. volume of one bag cement) or in multiple of the same.

Learn MoreMay 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.

Learn MoreVolume Batching of Concrete: Volume batching of concrete is accomplished with the use of measurement boxes, locally named “farmas or gauge boxes”.
