Get Price84% 16% of 7 Aggregate Impact Value BS 812 Part 3 1 Objective To determine the aggregate impact value in the laboratory 2 Introduction Impact value of an aggregate is the percentage loss of weight particles passing sieve by the application of load by means of 15 blows of standard hammer and drop under specified test condition
Get PriceThe aggregate impact value is the ratio of the weight of the fraction passing through mm weight W2 by the total weight of the sample weight W1 W2 Aggregate Impact Value = W2/ W1 W2 100 = 80 gm / 300 gm = Impact Value Where W1= Weight of the fraction passing through a mm IS sieve 220 gm
Get PriceAggregate Impact Value Test Procedure as per IS 2386 Part Mar 30 2020The aggregate impact value test is an important test of aggregates It is done to obtain the resistance and impact of aggregates stones In this test a machine is used which is called impact testing machine
Get PriceThe apparatus of the aggregate impact value test consists of A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter Level and plane concrete floor of minimum 45 cm thickness are used to support it The base of the machine should also have provisions for fixing its base
Get PriceThe aggregate impact value is a measure of resistance to sudden impact or shock which may differ from its resistance to gradually applied compressive load APPARATUS 1 A testing machine weighing 45 to 60 kg and having a metal base with a painted lower surface of not less than 30 cm in diameter
Get PriceImported Aggregates Testing Since early 2024 Building and Construction Authority of Singapore BCA has adopted a three stage testing regime on imported aggregates to determine the quality of aggregates imported from overseas sources Since beginning Admaterials has provided imported aggregate testing for the following tests as required by BCA
Get PriceUTA 0650 The Aggregate Impact Value Testing Apparatus is robustly designed to determine the Aggregate Impact Value AIV of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact The number of blows delivered to the sample is automatically documented by the counter that is fitted to the machine
Get PriceThe aggregate should therefore have sufficient toughness to resist their disintegration due to impact This characteristic is measured by Impact Value Test The aggregate impact value is the measure of resistance to sudden impact of shock which may differ from its resistance to gradually applied compressive load Equipments
Get PriceAggregate Impact Value Used to determine the impact value of aggregates and select them for a given application The device has a trip action hammer release blow counter device and a built in operator safety device Heavy duty construction with hardened steel surfaces for minimum wear The complete assembly is cadmium plated for corrosion
Get PriceThe aggregates must thus have adequate rigidity to resist their breakdown due to excessive impact This property is calculated by impact value test The aggregate impact value is a calculation of the resistance to abrupt impact bang or shock which may vary from its resistance to steadily applied compressive weight Procedure
Get PriceAggregate impact value is used to classify the stones in respect of their toughness property as indicated below <10% Exceptionally strong 10 20% Strong 20 30% Satisfactory for road surfacing 35% Weak for road surfacing The aggregate impact value should not normally exceed 30% for aggregate to be used in wearing course of pavements
