Fine Aggregate
Fine aggregates are coarse to medium grained particulate material used in construction. Aggregate in concrete is a structural filler. Aggregate occupies most of the volume of the concrete. We carry a variety of fine aggregates. All of our fine aggregates are sold by the ton. We can sell you a full 5-gallon bucket of ...
BULKING OF FINE AGGREGATE
Due to bulking, fine aggregate shows completely unrealistic volume. Therefore, it is absolutely necessary that consideration must be given to the effect of bulking in proportioning the concrete by volume. If care is not given to the effect of bulking, in the case of volume batching, the resulting concrete is likely to be undersanded and harsh.
