Read MoreDec 21, 2012 Aggregate Crushing Value. This test helps to determine the aggregate crushing value of coarse aggregates as of impact value of coarse aggregate. ACV experiment on Crushing value detailed.Crushed aggregate requires slightly higher values. Fine aggregate content is usually 35 to 45 by mass or volume of the total aggregate content. CHARACTERISTICS OF AGGREGATES. The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following section Grading. Grading is the particle-size.

Experiment No1 DETERMINATION OF AGGREGATE CRUSHING VALUE 1 AIM The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied pressive load Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum.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.
Read MoreDec 19, 2019 The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low.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.

Conclusion From the experiment, we get 6.02 where it still not exceeding JKR's standard, 30 .So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.Conclusion From the experiment, we get 6.02 where it still not exceeding JKR’s standard, 30 . So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate are mild tough to have the resistance pressure under traffic wheel loads such as car, lorry, motorcycle and etc.

AGGREGATE IMPACT VALUE TEST-10+ IMPORTANT , It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact values are numerically similar within close limits For deciding the suitability of soft aggregates in base course construction, aggregate impact test is commonly.Jul 16, 2014 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 values are numerically similar within close limits.
Read MoreCoarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it.Feb 25, 2012 From the experiment, we get average percent wear are 22.34 still not exceeding JKR’s standard, 30 . So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
