Impact test the aggregate impact test is carried out to evaluate the resistance to impact of aggregates. aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing.

Aggregates affect, to a great extent, the load transfer capability of pavements. hence, it is essential that they should be thoroughly tested before using for construction. there are various tests are carried out to check the quality of the aggregate like abrasion test, impact test, soundness test, flakiness index.
Flakiness and elongation index shape test of aggregates as per is 2386 part i objective to determine the flakiness index and, to determine the elongation index of given aggregates sample. to assess suitability of aggregates for use in.
When the weight of cement is more, i.e. aggregate cement ratio is less, the concrete has more cement paste required to coat aggregates and fill the voids between them. this more cement paste makes the concrete relatively easy to mix, place and compact as it reduces the friction between aggregates and allows its smooth.
For the l.a. abrasion test, the portion of an aggregate sample retained on the 1.70 mm required for various grades of stone aggregates are given in table crushing.

Aashto test methods t 2 sampling of aggregates t 11 materials finer than 75 m no. 200 sieve in mineral aggregates by washing t 27 sieve analysis of fine and coarse aggregates t 84 specific gravity and absorption of fine aggregate t 85 specific gravity.
And coarse aggregates aashto t 27 scope the sieve analysis, commonly known as the gradation test, is a basic essential test for all aggregate technicians. the sieve analysis determines the gradation the distribution of aggregate particles, by size, within a given sample in order to determine compliance with.
Aggregates are evaluated through tests to determine their suitability for various applications. mineralogy, grain size and texture, and petrographic description of rock samples are also used to evaluate suitability. types of aggregates coarse aggregate. coarse-grained aggregates will not pass through a sieve with 4.75 mm openings no..
