Batching of Concrete Weigh Batching Volume Batching

Dec 10, 2020  Volume batching is performed using gauged boxes of inside dimensions of 350 millimeters by 400 millimeters by 250 millimeters. The box volume is 0.35 cubic meters, equivalent to the volume of one bag of cement. The nominal mix, which is 1:2:4, use one bag of cement, two boxes of sand, and four coarse aggregate boxes and mix them together.. Weigh

Methods of Batching Concrete - The Constructor

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. Fig 1: Gauge Box or Measuring Box.

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).
