Sep 14, 2010 · Cement has a specific gravity of 3.15, so a given volume of cement is 3.15 times as heavy as the same volume of water. Some materials, such as water (1) and portland cement (3.15), always have the same specific gravity.
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. The volume of gauge box is equal to the volume of one bag of cement. Gauge bow are also called as FARMAS. They can be made of timbers or steel.

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).
Mar 21, 2018 · 1. Batching. It is the main thing in the Concrete Manufacturing Process. The measurement of materials like aggregates, cement, water necessary for preparing different grades of concrete is Batching. It is by two processes. One is volume and other is weight batching. The volume batching is by mixing materials with its volume.
The dry volume of concrete mixture is always greater than the wet volume. The ratio of dry volume to the wet volume of concrete is 1.54. So 1.54 Cum of dry materials (cement, sand and aggregate) is required to produce 1 Cum of concrete. Volume of Cement required = 1/(1+2+4) X 1.54 = 1/7 X 1.54 = 0.22 Cum
Concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete. Some of these inputs include water, air, admixtures, sand, aggregate, fly ash, silica fume, slag, and cement.
9/16/2017 · he moisture present in aggregate forms a film around each particle. These films of moisture exert a force, known as surface tension, on each particle. Due to this surface tension each particles gets away from each other. Because of this no direct ...
For weigh batching of concrete , it is necessary to use the weights of the sand and aggregates. If a weigh batcher is used at site , then the nominal mix needs to be converted into weights. This post explains you how this conversion can be easily done.
Concrete batching plant is efficient concrete equipment, which is broadly applied in large quantities and long construction period concrete production projects because of its high mechanization, automation and productivity.

Here’s what the math looks like for a 10’ by 10’ concrete patio: 10 x 10 = 100 square feet; 4 ÷ 12 = .33; 100 x .33 = 33 cubic feet; 33 x .037 = 1.22 cubic yards; Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness.
This specification covers concrete made by volumetric batching and continuous mixing. Requirements for quality of concrete shall be either as hereinafter specified or as specified by the purchaser. When the requirements of the purchaser differ from this specification, the purchaser's specification shall govern.
Volume batching of concrete may be allowed only where weigh batching is not practical and for unimportant concrete or for any small job. As the strength and durability of concrete is largely dependent on proportion of ingredients and water cement ratio, weigh batching is must and recommended in place of volumetric batching of concrete. ...
