Aggregate crushing value Test Lab Report Adnan Abir. Aggregate crushing value Test Lab Report. Adnan Abir. Name of the experiment Aggregate Crushing value test. Objective 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road.
Aggregate Crushing Value Advantages. The aggregates crushing value test should be performed as per IS code 2386 Part IV. First fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate weigh and record it
This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30.
Determination Of Aggregate Crushing Value Lab Report. Advantages Aggregate Crushing Value Test Report Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions and the strength of the aggregate used in road construction is expressed by numerical index
May 17, 2019 Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load
Determination of aggregate crushing value545 . 3. APPARATUS The apparatus of the aggregate crushing value test as per IS 2386 Part IV 1963 consists of 1 A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1.
Aug 27, 2019 The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed or finer material obtained when the test sample
Determination Of Aggregate Crushing Value Lab Report. Advantages Aggregate Crushing Value Test Report Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions and the strength of the aggregate used in road ...
Oct 03, 2019 The strength of coarse aggregates is determined by aggregates crushing test. The aggregate crushing value test provides a resistance of aggregate to crushing under a gradually applied compressive load. To construct a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred.
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
May 05, 2010 Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.
1.The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place Aggregate Crushing Value BA X 100 where A weight of oven-dried sample B weight in g of fraction passing through 2.36 mm IS sieve. 6.Video Aggregate Crushing Value Test

DETERMINATION OF AGGREGATE CRUSHING VALUE. The apparatus of the aggregate impact value test as per IS 2386 Part IV 1963 consists of 7 A testing machine weighing 45 to 60 kg and having a metal base. Get Price
May 21, 2020 Therefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test.
Alan Impact value of an aggregate is the percentage loss of weight particles passing2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop,under specified test condition. 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 their resistance to a slowly applied ...
Jul 16, 2014 Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate. Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact ...
