How Coarse Aggregate Affects Mix Design of …
2. Grading of Coarse Aggregate. Grading is the determination of the particle-size distribution for aggregate. It affects the amount of cement and water requirements, workability, pumpability, and durability of concrete. The grading of coarse aggregate is important to get cohesive and dense concrete.
SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85

What is a coarse aggregate? - Quora
Coarse aggregate is the portion of the concrete which is made up of the larger stones embedded in the mix. Concrete contains three ingredients; Water, cement, and aggregate. That aggregate is made of fine sand and coarse gravel.
Density of Aggregate - Bulk and Relative Density - …
For aggregates, density is determined by multiplying the relative density (specific gravity) of the aggregate times the density of water. Bulk Density of Aggregate [1] The bulk density or unit weight of an aggregate is the mass or weight of the aggregate that required …
Saturated-surface-dry - Wikipedia
Saturated surface dry (SSD [citation needed]) is defined as the condition of an aggregate in which the surfaces of the particles are "dry" (i.e., surface adsorption would no longer take place), but the inter-particle voids are saturated with water. In this condition aggregates will not affect the free water content of a composite material.. The water adsorption by mass (A m)) is defined in ...

Specification of Coarse Aggregate | Coarse …
Precautions while using coarse aggregate The following precautions should be taken while using coarse aggregate in RCC (Reinforced Cement Concrete) Work. 1. Aggregate should be stacked on a hard, dry and level patch of ground. 2. Coarse aggregate should not contain any material liable to attack steel reinforcement. 3.
Moisture Content - Pavement Interactive
The moisture content of an aggregate is expressed as: If the moisture content is positive, the aggregate has surface moisture and will contribute water to the PCC, while if the moisture content is negative the aggregate is air dry to some degree and will absorb moisture from the PCC. Related Tests. Typical moisture tests are:
