Aggregate - AfriSam

factor, eg concrete used for radiation shielding is made from high-density aggregate. In addition, the relative density of the aggregate is used in calculating the absolute or solid volumes of materials in a concrete mix and thus the yield. The apparent relative density of aggregate generally varies between 2.5 and 3.0. Water absorption

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%. Note: Fine aggregate do not show any bulking when it is absolutely dry or completely saturated.

The Effect of Aggregate Properties on Concrete

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

What is Bulking of Sand and Test to Calculate Bulkage of Sand?

Bulking of sand is the increase in the volume of sand due to the presence of moisture on the sand particles. The presence of moisture in aggregates cause the bulking of sand which may affects the design strength of concrete. The extent of bulking depends on the percentage of moisture present in the sand and on its fineness.
