With most particles going through a 3/8-inch sieve, fine aggregates typically consist of natural sand or crushed stone. All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter. Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.

Optimized Gradation – Best Practices • Defining coarse sand (between the #4 and #30) and fine sand (finer than the #30) • ACI 302.1R-04 recommends the sum of material retained on the #8 and #16 sieves should be a minimum of 13% to avoid edge slumping
The cost of grinding to a higher fineness is considerable, and also the finer the cement the more rapidly it deteriorates on exposure to the atmosphere; Finer cement leads to a stronger reaction with alkali-reactive aggregate, and makes the cement paste, though not necessarily concrete, exhibit a higher shrinkage and a greater proneness to ...

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

Practical Grading of Aggregates Concrete Technology. The suitability of the fine sand of zone 4 for use in reinforced concrete should be tested. For sands, the sand content of the mix should be low whose greater part is smaller than 60C micron. In general, finer the grading of the fine aggregate, higher should be the coarse/fine aggregate ratio.
Grading of aggregate is the particle size distribution, which is determined by sieve analysis. The particle size distribution of a mass should be such that, voids between the coarse aggregate should be filled by fine aggregates. The grading of the aggregate affects the workability of concrete. When grading of aggregate is done by sieve analysis.
