There is an optimum coarse to fine aggregate ratio for RCCP. • Increasing cement from 9% to 12% has significant effect on the properties of RCCP. • Coarse to fine aggregate ratio influences the porosity of RCCP. • Relationship between tensile strengths and compressive strength were determined.
Common aggregate can be classified into coarse aggregate and fine aggregate. The aggregates which particle size is larger than is called coarse aggregate, including gravel, crushed stone, slag, etc. The aggregates which particle size is less than is called fine aggregate, including the fine and medium natural sand, sand, fly ash.
Difference Between Fine and Coarse Aggregate. Aggregates are end product on their own and also used as the raw material in concrete mixtures. Sand, gravel or crushed stone are the essential ingredients in the concrete mix and account approximately 60% to 75% of the total volume of the concrete.

IUBAT International University of Business Agriculture and Technology College of Engineering and Technology (CEAT) CEN 214: Civil Engineering Materials Lab Sieve Analysis of Fine and Coarse Aggregate RELATED THEORY The term sieve analysis is given to the operation of dividing a sample of aggregates into fraction each consisting of particles between specific limits.
Fine aggregate is used in many fields in sites for many the determination of specific gravity of fine aggregate is very essential. Specific gravity of fine aggregate can be defined as the ratio of the weight of given volume of coarse aggregate to the weight of given volume of distilled water.
In grading of aggregates, well graded sand from coarse to fine has less voids than fine sand. The lesser the voids the better is the quality of sand for use in cement concrete, provided there is no silt in sand. The combined aggregate when mixed with the required quantity of cement and water, should give a good workable concrete which can be ...

• Aggregates are divided into either 'coarse' or 'fine' categories. Coarse aggregates are particulates that are greater than The usual range employed is between and in diameter. Fine aggregates are usually sand or crushed stone that are less than in diameter.
Aggregates larger than ¼ inch are classified as coarse aggregate, while anything smaller than ¼ inch is termed fine aggregate. As a general rule, the largest aggregate should be no greater in diameter than onethird the depth of the slab, or onefifth the smallest dimension of the form.
The stiffness values of the original fine and coarse aggregates are assumed to be the same as those of the new natural fine and coarse aggregates, respectively. Based on these assumptions, the amplification factor, φ RAC /φ NAC, is proposed, as given by Eq.
