  • BULKING OF FINE AGGREGATE WHAT, WHY & HOW?

    The volume increase of fine aggregate due to presence of moisture content is known as bulking. Fine sand bulks more as compared to coarse sand. Extremely fine sand particularly the manufactured fine aggregate bulks as much as about 40%.

  • Engineering Materials: Bulking of Aggregates

    Mar 04, 2011· The increase of volume of given weight of aggregates due to the presence of moisture is called bulking of aggregates. 5 to 8 percent of moisture of aggregate weight cause 20 to 30 percent volume increase. This because of the creation of thin film Properties Considered in Mix Design Superpave Mix Design,VMA is most affected by the fine aggregate fractions which pass the No. 200 sieve. The reason for this is that these particles tend to be absorbed by the binder film. Because they take up volume, there is a tendency to bulk (extend) the binder resulting in a lower VMA.

    The increase in volume is known as “Bulking” The amount of Bulking increases initially with increase in water content but decrease to zero with further increase in water content over to bulking, Fine aggregate shows completely unrealistic volume. Therefore it is absolutely necessary that consideration must be given to the effect of bulking.BULKING OF FINE AGGREGATE WHAT, WHY & HOW?,Aug 02, 2017· 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.

  • Bulking of Sand The Construction Civil

    The reason is that moisture causes film of water around sand particles which results in the increase of volume of sand. For a moisture content percentage of 5 to 8 there will be an increase in volume up to 20 to 40 percent depending upon sand. If the sand is more fine there will be more increase in volume. This is known as bulking of sand.Exp 5 Bulk Density Civil Engineers PK,This test method is used to determine the bulk density of the given fine grained specimen. During the concrete mix design, when the aggregate is to be batched by volume or by weight, then it becomes necessary to know the mass of the aggregates that will fill the container of unit volume.
