The density of concrete is increased by 5 to 7% when using coarse aggregate that is 100 percent slag, rather than natural aggregate, as a reference . Recent researchers reported that the split tensile, flexural, and compressive strength of steel slag aggregate concrete were higher than the control mix [ 7, 14, 15 ].

5.1 Relative density (specific gravity) is the ratio of mass of an aggregate to the mass of a volume of water equal to the volume of the aggregate particles – also referred to as the absolute volume of the aggregate. It is also expressed as the ratio of the density of the aggregate particles to the density of water. Distinction is made between …

The bulk density or unit weight of an aggregate is defined as the mass of the aggregate per unit volume. it is expressed in kg/liter. What is the value of Coarse Aggregate Density? Most of the aggregates possess a relative density within 2.4 – 2.9 with a similar particle density about 2400-2900 Kg/m 3 (150-181 lb/ft 3 ).

When converting from one unit to another, it is crucial to keep in mind the density of the material being measured. For aggregates, the density is typically measured in tons per cubic yard (ton/cy). To convert 1 ton of aggregate to cft, we must first determine the material's density. The standard density for aggregates is 1.5 ton/cy.

The smallest sieve through which 100 percent of the aggregate sample particles pass. Superpave defines the maximum aggregate size as "one sieve larger than the nominal maximum size" (Roberts et al., 1996 [1]). Nominal maximum size. The largest sieve that retains some of the aggregate particles but generally not more than 10 percent by weight.
