For ASTM C136 sieve analysis of aggregates, the manual provides a bigger picture of the method. Sieving equipment, practices, sieve maintenance, and some requirements of the ASTM E11 for specification for test sieves are discussed. Part of this section provides an explanation of the definition and function of fineness modulus that goes beyond

The absorption and surface moisture of aggregates should be determined according to ASTM C 70, C 127, C 128, and C 566 (AASHTO T 255) so that the total water content of the concrete can be controlled and correct batch weights determined

Aggregate crushing value formula is given below, Aggregate crushing value = (W3 / W) or W3 / (W2 – W1) W1 = Empty weight of cylindrical Measure. W2 = Weight of Aggregate with Cylindrical Measure. W = W2 –W1 = Weight of Aggregate Sample. W3 = Weight of crushed aggregate sample passed through 2.36 mm IS Sieve

minimum cross-sectional area. Specifications contain requirements for percentage of crushed aggregate particles, with the purpose of maximizing shear strength in either bound or unbound aggregate mixtures. This method may be used in determining the acceptability of coarse, dense-graded, and open-graded aggregates with respect to such requirements

virgin aggregate particles in the original concrete1-3. ASTM C 33, Specification for Concrete Aggregates, includes a requirement of an abrasion loss (by ASTM C 535) of less than 50% for aggregates used in concrete construction and less than 40% for crushed stone used in pavements4

the durability index of the aggregate based upon the grading of the aggregate as determined in 9.4. 9.5.1 If less than 10 % of the aggregate passes the No. 4 (4.75-mm) sieve, test coarse aggregate (Procedure A) only. 9.5.2 If less than 10 % of the aggregate is coarser than the No. 4 (4.75-mm) sieve, test fine aggregate (Procedure B) only

Most kinds of rocks can produce acceptable aggregates that conform to ASTM C33. Thus, aggregates are not generally classified by mineralogy; the simplest and most useful classification is on the basis of specific gravity. Aggregates are classed as heavyweight, normal-weight, and lightweight. Most commonly used aggregates such as sand, gravel, and crushed stone, produce freshly mixed normal

Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone

Nov 05, 2019 TESTING OF AGGREGATE CRUSHING VALUE. Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased. It is tested in accordance with BS 812:110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing. The allowable range is 17- 41
