Introduction to Aggregates . Aggregates have many varied uses in transportation systems. The desirable properties and appropriate specifications are typically governed by the end use of the materials. In other words, aggregates that are well suited to a stabilized permeable base material may not be suitable for use in a PCC mixture.

For instance, deleterious particles (Figure 2) are often lighter than aggregate particles and therefore, a large amount of deleterious material in an aggregate sample may result in an abnormally low specific gravity.

This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete. An experimental program based on two variables (proportion of fine aggregates replacement and proportion of coarse aggregates replacement) was implemented. The proportions of replacement were 0%, 50%, and 100% by mass of aggregates.

This gives a stronger and denser concrete. Rounded aggregates give a more workable mix. Angular aggregates make concrete harder to place, work and compact, but can make concrete stronger. STORAGE Aggregates should be stored where they will stay clean, separated from other materials and dry. If the aggregates are very wet use less water in the mix.

Short‐run aggregate supply curve.The short‐run aggregate supply (SAS) curve is considered a valid description of the supply schedule of the economy only in the short‐run. The short‐run is the period that begins immediately after an increase in the price level and that ends when input prices have increased in the same proportion to the increase in the price level.
