Specific gravity and absorption are fundamental aggregate properties needed for hotmix asphalt (HMA) and Portland cement concrete (PCC) mix design and/or volumetric determinations. The definition of specific gravity can be given as the ratio of the mass of a given volume of aggregate to the mass of an equal volume of water at a stated temperature.

SPECIFIC GRAVITY OF AGGREGATE 1. Objective Specific Gravity is defined as the ratio of Weight of Aggregate to the Weight of equal Volume of water. The specific gravity of an aggregate is considered to be a measure of strength or quality of the material. Aggregates having low specific gravity are generally weaker than those with high specific

Specific Gravity Specific gravity refers to the relative (as compared to water) density of a unit volume of aggregate. Specific gravity of the aggregate generally is indication of its quality. A low specific gravity may indicate high porosity and therefore poor durability and low strength. The range of specific gravity for aggregates is generally between and

May 28, 2010· When calculating the bulk specific gravity of an aggregate, take both the volume of the aggregate and all its pores into consideration. These pores will likely contain a certain level of moisture that will affect the performance of the concrete if appropriate corrections are not made to account for the actual moisture content of the aggregates.

If the cement has exposed to extreme moisture content then, the specific gravity of cement will differ because of the moisture content present in the pores. Every material has solid particles and pores which may contain water in it. Normally our nominal mix design is based on the value of specific gravity of cement as The value will change over time if the cement is exposed to various weather conditions.
