For aggregates that are considered deleterious admixtures such as fly ash can be placed into the mix to help improve the stability of the concrete mix. 2,7 Specific Gravity and Absorption (ASTM C 127/C 128, AASHTO T-85/T-84): Specific Gravity evaluates how voids in the aggregate particles are considered.
The crushed granite stone having a 16 mm nominal particle size was utilized. The physical properties of the natural crushed stone aggregate and IFS were tested as specified in IS-2386 (equivalent to ASTM C127 / ASTM C131 /ASTM C136), and it is given in Table.2. The particle size distribution of the coarse aggregate is shown in Fig. 4. 2.1.4.
Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass.
Crushed stone: If you hear the generic "crushed stone" term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

Although the guidelines get complicated, a mortar volume fraction of 50% is about right for most mixes using clean, rounded gravels, and closer to 60% for crushed stone mixes. This is because the mortar separates the aggregate particles and rougher textures require more separation to achieve workability, pumpability, and finishability.
Usually, the natural river sand is used as a fine aggregate. But at places, where natural sand is not available economically, the finely crushed stone may be used as a fine aggregate. The material which is retained on BIS test sieve no. 480 is termed as a coarse aggregate. The broken stone is generally used as a coarse aggregate.
