2019-11-16 AGGREGATE IMPACT VALUE TEST Object of the Experiment To evaluate the toughness of a stone i.e. the resistance of the aggregates to fracture under repeated impacts is called Impact Test. This test is done to determine the aggregate impact value of coarse aggregate as per IS 2386 (Part-IV) 1993. Aggregate Impact Value Test as per Read More

2014-8-6 AGGREGATE IMPACT VALUE Experiment No: 5 Date: AIM: To determine the impact value of the given aggregates. GENERAL:- The property of a material to resist impact is known as toughness. Due to movement of vehicles on the road aggregates are subjected to impact resulting in their breaking down into smaller pieces.

2012-2-8 Impact test may either be carried out on cylindrical stone specimens as in Page Impact test or on stone 1aggregates as in Aggregate Impact test. The Page Impact test is not carried out now-a-days and has also J.been omitted from the revised British Standards for testing mineral aggregates.

2021-6-3 Steel ball bearings in the hardness test To produce the abrasive action using standard steel balls that, when mixed with the aggregate and rotated in a drum for a specific number of revolutions, impact the aggregate.. The wear per age due to friction with steel balls is determined and is known as the abrasion value. Prepare the sample by the portion of an aggregate sample retained in the 1.70

Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is carried out by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine.

The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2. Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and <25% for wearing surfaces like
