ACI Mix Design – Pavement Interactive

Coarse Aggregate Content. Selection of coarse aggregate content is empirically based on mixture workability. ACI recommends the percentage (by unit volume) of coarse aggregate based on nominal maximum aggregate size and fine aggregate fineness modulus.

Aggregate Specific Gravity – Pavement Interactive

These air voids within the aggregate particle (Figure 1) can become filled with water, binder or both (Figure 2). It takes a finite amount of time for water/binder to penetrate these pores, so specific gravity test procedures generally contain a 15 to 19-hour (for AASHTO procedures) or a 24-hour (for ASTM procedures) soak period for the purpose of allowing penetration into these pores.

Coarse Aggregate In the construction industry, coarse aggregate is one of the most important building material since it is massively used in the said industry. Coarse aggregates are made up of rocks quarried from ground deposit and are typically used in the construction of roads as well as in making of concrete as it provides volume, body, and strength when mixed.
