Aggregate (composite) - Wikipedia

Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel

Combined Gradation Example - mdt.mt.gov

These aggregates meet the requirements of Section 701.01 AGGREGATE FOR CONCRETE of the Standard Specification with the exception of Coarse Aggregate #2. Coarse Aggregate #2 doesn't meet the gradation requirement of Section 701.01.

Fine Aggregate Specific Gravity - Pavement Interactive

Overview. The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the coarse aggregate specific gravity test.. Figure 1: Fine aggregate specific gravity sample and pycnometer.

HOW COARSE AGGREGATES AFFECT MIX DESIGN?

As maximum size of coarse aggregate reduces, surface area of coarse aggregate increases. Higher the surface area, greater is the water demand to coat the particles and generate workability. Smaller maximum size of coarse aggregate will require greater fine aggregate content to coat particles and maintain cohesiveness of concrete mix.
