What is ASTM C136?
ASTM C136, 2006 Edition, February 15, 2006 – Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates. This test method covers the determination of the particle size distribution of fine and coarse aggregates by sieving.
What is the standard for sieve analysis?
The sieves normally used are the standard 8 inch (200 mm) sieves. With Fine Aggregate the coarse sieve or the 3/8” (9.5 mm) sieve at the top; each sieve below is finer; and the finest sieve, a No. 200 (75 µm) is at the bottom.
What is the minimum weight of fine aggregate for sieve analysis as per ASTM C136?
ASTM-C136- designates minimum of 500 grams (4.76 mm.) dry weight for fine aggregates – i.e., material with at least 85 percent finer than a No. 4 Sieve and more than 5 percent coarser than a No. 8 Sieve.
What is the specification grade for concrete fine aggregate?
Fine aggregates pass the 3/8-inch sieve and are retained on a #200 U.S. sieve. Fine aggregate consists of natural sand, manufactured sand, or a combination….Table 13. ASTM Gradation Specifications for Fine Aggregates. for Portland Cement Concrete.
| Sieve | Percent Passing |
|---|---|
| 1.18 mm (No. 16) | 50-85 |
| 0.60 mm (No. 30) | 25-60 |
Is 90 micron a sieve?
90 micron sieve is having aperture size 90 micron. After sieving, the coarser particle left on screen is called residue. The percentage residue left on screen of 90 micron sieve is called Fineness of cement.
What is a #4 sieve?
The numbered sieves refer to the number of square openings per inch (25.4 mm-so a #4 sieve has 1/4-inch (4.75-mm) square openings; a #16 has 1/16-inch (1.18-mm) square openings. …
How do you interpret sieve results?
When you hear the term test sieve analysis results, it is referring to the distribution of particles in a given sample. This can be interpreted by analyzing the retention of particles throughout a sieve stack or the amount of material that passes through each sieve.
How does ASTM define fine aggregate?
This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Fine aggregate shall be free of injurious amounts of organic impurities.
