AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead

between aggregate crushing value (ACV) and ten percent fines aggregate crushing value (TFV) for some aggregates in Nigeria. Such a mathematical relationship, usually established through regression modelling on data collected, is useful in saving time and money cost on site through estimating one variable when another is known

1.1 Aims And Objective ... under the basement complex of Nigeria with some parts having relatively high relief while others have low ... 2.2.4 Aggregate Crushing Value (ACV) Test The aggregates were sieved to pass through sieve 12.5mm and retained in B.S sieve 7mm. About 700g

Aggregate Crushing Value Test Viva Questions. Aggregate crushing value. -3-111.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

aggregate crushing value test conclusion deferrence between ten percent fines value of aggregates and aggregate crushing value procedure of aggregate ... Granite Stone In Cross River State Of Nigeria

These two aggregate samples were tested for sieve analysis test, relative density test, water absorption test, ten percent fine test, aggregate crushing value test (ACV), Aggregate impact value test (AIV), and Abrasion value test. Findings revealed that the best aggregate for road construction is the aggregate from Isi-Agu

1. objective. The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead

The aggregate crushing value gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. The average aggregate crushing value of the sample was obtained as 13.47% as shown in Table 4. Tab. 4 - Results of Aggregate crushing value (ACV) test. S/N ACV 1 ACV 2 ACV 3 AVERAGE ACV

Table 4: Specified Properties of Aggregate Test and Obtained Result from Kuta river gravel. S/No Properties Specified Standard Results obtained (River Agg) 1 Specific Gravity 2.4 – 2.9 2.65 2 Water absorption 0.2 – 1.5 0.947 3 Aggregate Crushing Value ≤ 30 26.3 Figure 1: Gradation of river gravel 0 10 20 30 40 50 60 70 80 90 100

In most cases, British standard (BS EN 932, 2010, BS EN 933, 2010 and BS EN 1097, 2010) and the American Society for Testing and Material (ASTM C-131, 1989, ASTM C-535, 1989) give the standards for testing the aggregate properties. Aggregate impact value (AIV), aggregate crushing value (ACV) and ten percent fines (TFN) value are common tests

3.1 Aggregate Crushing Value: The results of the crushing as presented in Table 1 and Table 2 shows that value for coarse aggregate is 21.1% and that of pumice aggregate is 28.4% respectively. 3.2 Aggregate Impact Value: The results of the impact test as presented in Table 3 and 4 shows that value for coarse aggregate is 16.11% and that of

Aggregate Crushing Value (ACV) test indicates the resistance to crushing under gradually applied crushing load. It is measured as percentage of aggregates passing through 2.36 mm IS sieve after specimen subjected to a compressive load of 40 tonne at the rate 4 tonne per minute and to the weight of aggregates taken

1.0 AGGREGATE IMPACT VALUE TEST 1 1.0 INTRODUCTION Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads if the aggregates are weak, the stability of the pavement structure is likely to be adversely affected

Sep 12, 2015 Crushing Test Fig-1 Crushing Test Setup. One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS: 2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied

Aggregate Impact Value. AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of coarse aggregates as per IS: 2386 (Part IV) – 1963

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
