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 ...
Read More Aggregate Crushing Value Test Procedure and Result. Objectives of Impact Value Test. This method of test used to measure the impact value of aggregate use in the construction of Highway pavement and concrete structure. Reference-Aggregate impact value
aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or metamorphic rocks, but geological type does not by itself make an aggregate
Feb 15, 2019 Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.

The aggregate shall be taken as in the case of crushing strength value test i.e., the aggregate should pass through 12.5 mm I.S. sieve and retained on 10 mm I.S. sieve. It should be oven dried at 100C to 110C for four hours and then air cooled before test.
Abrasion Value (Ag Bg) / Ag X 100. you May Like Stripping value Test of Road Aggregate. Uses of Los Angeles Test Values for Road Design . Los Angeles Abrasion test is normally used to measure aggregate hardness, toughness, and abrasion resistance with respect to scuffing, scratching, wearing, marring, rubbing, and disintegration.
The crushing of disintegrated rocks manufactures Coarse Aggregates. 2 The particle size is less than 4.75mm. The particle size is greater than 4.75mm. 3 Fine Aggregates are used in concrete as filler material to fill the voids that are formed between the coarse aggregate.
Oct 12, 2015 The Los Angeles abrasion value (LAAV) test is the most widely used method for measuring aggregate resistance to abrasion. The test measures the resistance of aggregate to wear due to attrition between rock particles and also to impact and crushing by steel spheres (Kahraman and Fener 2007). Aggregate crushing value (ACV) and aggregate impact ...
The aggregate crushing value is obtained by the following expression Where W 1 Total weight of dry sample . W 2 Weight of material passing 2.36 mm I.S. sieve. The aggregate crushing value provides an indirect measure of the crushing strength of the road aggregate. The strong aggregates possess low aggregate crushing value.
Mar 25, 2013 Briefly explain the aggregate crushing value test procedure. ROAD AGGREGATES For the L.A. abrasion test, the portion of an aggregate sample retained on the 1.70 mm required for various grades of stone aggregates are given in Table
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source IS 2386 (Part 4)1963)
Jul 18, 2021 Aggregate crushing value (Weight of fraction passing through the 2.36 mm sieve) / (Weight of surface dry sample) (W 2 x 100) / (W 1-W) Where W is the weight of empty cylinder. Result. The mean of the two results shall be reported to the nearest whole number as the aggregate crushing value of the size of the material tested.
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 (Part IV) 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes 12.5mm, 10mm and 2.36mm Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm
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%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for ...
