Coarse Aggregates All Coarse Aggregates A special requirement placed on all coarse aggregates deals with the restriction on the number of flat and elongated pieces. Section 904.03 sets the limits for the number of flat and elongated pieces. A flat and elongated piece is defined as one having a ratio of length to thickness greater than five.

Jan 09, 2018· Aggregate Impact Value Test. AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from Its resistance to a slow compression load.

To determine the aggregate crushing value of coarse aggregates as per IS: 2386.as per require IS code, thus, it is a suitable to use results in increased consumption of natural aggregate mechanical properties like crushing value, Impact.

The size of the aggregate bigger than 4.75 mm is considered as the coarse aggregate i.e. basically, all other aggregates which are retained on 4.75mm IS sieve while sieve analysis is performed. According to sources of coarse aggregates, it can be further classified as: (a) Uncrushed Gravel or Stone: It results from natural disintegration of rock.

3. Results and Discussions 3.1. Crushed Aggregate’s Effects on Slumps of Concrete. The Figure 1 depicts slum value of A-1 coarse aggregates for all five groups. For Impact Crushed (A-1) coarse aggregates slump values were evaluated for all five groups and it was evident from experiment that, there was a steady decrease in slump value with the decrease of w/c ratio.

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.

Both coarse aggregates and fine aggregates are the main constituents of concrete because they not only give the body to the concrete, it also have a significant effect on the fresh concrete based on aggregate’s shape, size, texture, grading and crushing type. Moreover it is proved that aggregate’s types has the severe effect on physic-mechanical properties of concrete as aggregate
