Effect Of Sieve Grading Of Fine Aggregates In Concrete

Aggregates for Concrete - Department of Civil Engineering

aggregate size numbers. Fine aggregate or sand has only one range of particle sizes for general construction and highway work. The grading and grading limits are usually expressed as the percentage of material passing each sieve. Fig. 5-6 shows these limits for fine aggregate and for one size of coarse aggregate.

The Effect of Aggregate Properties on Concrete - engr.psu.edu

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. When determining the strength of normal concrete, most concrete aggregates are several times stronger than the other components in concrete and therefore not a …

When we design mix the concrete, its target strength is much less than the compressive strength of the aggregates used in the formation. It can also be clearly seen in the mix design procedure that greater the maximum size of coarse aggregate used, less is the cement required to achieve the target strength.
