Difference Between Fine and Coarse Aggregate Civil

Fine aggregate and coarse aggregate are two main types of aggregate for concrete. As the name indicates, they are basically classified depending on the sizes of aggregate particles. Fine Aggregate vs Coarse Aggregate. Fine and coarse aggregates have some major differences. Sources of main differences between deep and shallow footings are definition, size of particles, materials, sources

Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm.

Practical Grading of Aggregates Concrete Technology

Grading of Fine and Coarse Aggregates: For all important works coarse and fine aggregates are batched separately, hence their grading should be known and controlled. Grading curves of the four zones of fine sand of table 4.3 as per I.S. 386 Part-I 1963 are shown in Fig. 4.16 to 4.19. The grading curve of any fine aggregate falling wholly within the limits of any one zone is considered suitable

A gap graded concrete describes a concrete mix where there is a gap between the fine aggregates and the coarse aggregates. A gap graded concrete mix is shown in the below diagram. Gap graded concrete mixes require more cement and then well graded aggregate concrete mixes and often become sticky and difficult to finish due to the large fine aggregate content.

Introduction to fine aggregates: The maximum size used is 80 mm and the range of 80 mm to 4.75 mn is known as coarse aggregate and 4.75 to 150 µm is called fine aggregate. Size 4.75 mm is common for both fine and coarse fractions. Qualities of fine aggregates: Fine aggregate should be clean i.e. it should be free from lumps, organic material, etc.

A Detailed Guide on Grading of Aggregates.

The basis for mixing coarse and fine aggregates of specific fineness modulus is the presence of voids or open spaces when the aggregates are packed together. In pure coarse aggregates packing may leave 30-40 percent voids, which can be removed only by filling with finer particles. Similarly, in fine aggregates also, voids are left that have to be filled with still finer particles (of cement
