performance record, the aggregates should be tested before they are used in concrete. The most commonly used aggregates—sand, gravel, crushed stone, and aircooled blastfurnace slag—produce freshly mixed normalweight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale,

Fine Aggregate Gradation • Fineness Modulus (FM) should be between and • FM is empirical # determined by dividing the sum of percent retained on a standard series of sieves by 100 (No. 4, 8, 16, 30, 50, 100) • Coarser fine aggregate has a higher FM Sieve Percent Passing 3/8 in 100 No. 4 95100 No. 8 80100 No. 16 5085

08/03/2016 · (8) California Bearing Ratio (CBR) values for RAP material containing trap rock aggregate have been reported in the 20 to 25 percent range. However, when RAP is blended with natural aggregates for use in granular base, the asphalt cement in the RAP has a significant strengthening effect over time, such that specimens containing 40 percent RAP ...

This test method determines the amount of material finer than the No. 200 sieve in aggregate by washing. Procedure A shall be used unless otherwise specified. When accurate determinations of material finer than the No. 200 in fine or coarse aggregate are desired, this test method is used on the aggregate sample prior to

over each test site. Density tests were made with a water balloon volu­ meter during various stages of the rolling operation. The data are being used in an attempt to define a mathematical or graphical expression for the maximum field density of the material relative to the percentage of coarse aggregate present.

30/08/2017 · The soft aggregates will be quickly ground to dust, whilst the hard aggregates are quite resistant to crushing effect. The test also will determine the quality of the aggregate. The Abrasion test is widely used as an indior of the relative quality or competence of mineral aggregates.

The values derived from either of these procedures will provide you with specific information about the durability of a sample aggregate. Samples are prepared to combine specific masses of particle size fractions, processed in the devices according to the relevant test methods, then washed over a specified sieve to determine percentage loss ...

The values stated in either SI units or inchpound units are to be regarded separately as standard, as appropriate for a specifiion with which this test method is used. An exception is with regard to sieve sizes and nominal size of aggregate, in which the SI values are the standard as stated in Specifiion the text, inchpound units are shown in brackets.

Water absorption (percent of dry weight) = W B − W A W A ×100 W B W A W A × 100 %. Where, W A is Dry weight of aggregate (The weight in g of ovendried aggregate in air) W B is Weight of aggregate immersed in water (The weight in g of the saturated surkedry aggregate in air) Note: Water absorption shall not be more than 2% per unit by weight.

Aggregate Crushing Value Test Step By Step Procedure. Aggregate Crushing Value ACV can be determined by using a simple formula This test is repeated once or twice and the average crushing value of the aggregate is determined The average crushing value in the different tests is the actual crushing value of aggregate Important points to remember 1It is recommended that the crushing .

Percent Fractured Face Test. A sample retained on the mm (No. 4) sieve is collected and the number of particles with fractured faces is compared to the number of particles without fractured faces. A fractured face is defined as an "angular, rough, or broken surface of an aggregate particle created by crushing, by other artificial means ...

C702/C702M Practice for Reducing Samples of Aggregate to Testing Size. D75/D75M Practice for Sampling Aggregates. D2419 Test Method for Sand Equivalent Value of Soils and Fine ...

This test method provides a standard procedure for determining the acceptability of coarse aggregate with respect to such requirements. Specifiions differ as to the number of fractured faces required on a fractured particle, and they also differ as to whether percentage by mass or percentage by particle count shall be used.

figure of aggregate crushing value test ellul. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load. The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected. Get ...

Values derived from both the Micro Deval and the Abrasion tests offer information about the performance of aggregate in use. This testing offers insight into how asphalt and concrete aggregates will stand up to wear and tear over time. It's also a good indior of changing properties in an aggregate source as part of quality control or ...
