MEASURING BOX USED IN SITE In volumetric batching of concrete, the ingredients of concrete are measured by their volume before they are mixed for making the durable concrete. The concrete ingredients are measured in measurement boxes of standard size. The measurement boxes are also known as “Farmas” or “Gauge Boxes”. Workers use troughs for the measurement of concrete ingredients on site. But, it is not a proper way to measure the quantity of concrete ingredients for making designed concrete. To ensure the uniformity of proportions and aggregate grading in succeeding batches, the proper and accurate measurement of all the material used in concrete making is necessary. For volumetric batching, it is convenient to make steel or wooden boxes (farmas) of various sizes/ volumes. In an ideal case, the volume of the farma is made equal to the volume of one bag of cement i.e. 35 liters or multiple thereof. The farmas are made comparatively deeper with the narrow surface ra...
