Aggregate Impact Value on Coarse Aggregates Apparatus for Aggregate Impact Test The apparatus as per IS: 2386 (Part IV) - 1963 consists of: (i) 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. Detailed Impact Test on Road Aggregates with calculation of Impact value has been shown, also range of aggregate impact value is explained.Toughness is the p. To determine Aggregate Impact Value Using Impact Testing Machine. Apparatus: – Impact Testing Machine: – Weight of hammer is 13.5 to 14.0 kg and Height of Fall is 380±5 mm. Sieves: – required are 12.5, 10.0 and 2.36 mm. Weight Scale: – To measure Weight of the sample. Procedure: – REPARATION OF SAMPLE i) The test sample should .The testing machine then places the measure, with the aggregate in it. An impact load is exerted by releasing a hammer from a known height to strike the aggregate. The impact value is calculated as the resulting percentage of fines generated. Procedure. Collect the aggregate pattern passing via a 12.5 mm sieve and retained on a 10 mm sieve.
Gilson aggregate testing equipment measures and evaluates the physical characteristics of fine and coarse aggregates for asphalt and concrete mixes. Size, shape, density, and strength of mineral aggregate all impact the long-term performance of . 5.1 Impact Value, as determined using the standard 4.5 kg (10 lbm) hammer, has direct application to design and construction of pavements and a general application to earthworks compaction control and evaluation of strength characteristics of a wide range of materials, such as soils, soil aggregates, stabilized soil and recreational turf. Impact Value is .

(rlv;Sld). 2. ISt 5640.1970 2.1 The impact testing machine of the general form shown in Fig. I and complying with .This video (Animation, Animated Video) explains how to determine aggregate impact value (Aggregate Impact Test). Aggregate test || Coarse aggregate Test (Civ.To study the toughness property of the aggregates for concrete construction. EQUIPMENT. Impact testing machine: DESCRIPTION OF MACHINE. The Pendulum impact Testing Machine consists of the robust frame, the specimen support and measuring dial. The pendulum shaft is fitted in anti friction bearings. The pendulum is clamped to the pendulum shaft. The primary purpose of this test is to ensure that only durable and robust aggregates are used in construction. The test involves the use of a testing machine to subject the aggregates to impact loads. The machine comprises a base, cylindrical measure, and a hammer that falls through a given height to cause an impact on the aggregates.
