3. Option C is a mixed option. It requires the concrete producer to select the mix proportions with the min-imum allowable cement content and compressive strength specified by the purchaser. BATCHING Batching is the process of measuring concrete mix ingre-dients by either mass or volume and introducing them into the mixer.
Mixing operations are either Batch type of Continuous. The preference of batch or continuous mixing is influenced by factors like the quantity of material to be blended, required degree of product homogeneity, pre-mixing and post mixing operations. This article explains the difference between batch mixing and continuous mixing. Batch mixing operation is discussed in details. The applications ...
The correct measurement of the various materials used in the concrete mix is called batching. It has been observed that batching errors are partly responsible for the variation in the quality of concrete. This operation can be properly and better controlled than other factors responsible for the variation in the quality of concrete.
