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.

Apr 23, 2019· Bulking of Fine Aggregate. The volume increase of fine Aggregate due to the presence of moisture content is known as bulking. This is due to the fact that moisture causes a film of water around sand particles which results in the increase of volume of sand, for moisture content of about 5 to 8%, this increase of volume may be a much as 20 to 40%, depending upon the grading of sand.

surface. The spacing between reinforcing bars also must be large enough to allow aggregate to move between the layers. Bolsters or support accessories such as chairs should be used to support the reinforcing mat(s). Reinforcement and supports should support foot traffic of the concrete placement crew without permanent downward displacement.
