The so-called absolute volume method is the most commonly used method. The first step of the absolute volume method is to calculate the volume of each ingredient of the concrete mix. However, as the batching plants are equipped with scales, their volume will have to be calculated in terms of kilograms.

Stock Pile Segregation

May 24, 2011 · In concrete products, aggregate segregation can also lead to inconsistent feeds into the batch plant. If your gradations are too coarse, the concrete products can be hard to place and the strength can decrease. If the gradations are too fine, the shrinkage increases, water demand goes up, you need more cement, and/or the strength decreases.

If aggregate is loaded on top of a conical stockpile then larger aggregate sizes are more likely to roll to the outside and bottom. Asphalt plants. Key portions of the plant generally concerned are (Brock, 1986 [10]; Kennedy et. al., 1987 [2]; AASHTO, 1997 [7]): Cold feed bins. Bins may not feed uniformly. Batch plant hot bins. Dust may collect ...

3 Common Aggregate Stockpile Problems

An even more common form of contamination involves aggregate from neighboring stockpiles. As loaders and work vehicles move on and around a stockpile, a certain proportion of aggregate naturally becomes displaced. If neighboring stockpiles happen to lie too close, the different aggregates may start to mix together.

By forming two stockpiles of fine aggregate, one for delivery and the other for mixing, this problem will be eliminated which will reasonably improve your chances of maintaining a uniform water-cement ratio during mixing. Weighing Materials. There are two ways of batching of aggregates for concrete mixes: by volume or by weight.
