Coarse Aggregate Sieve Analysis (#467 Stone) Nominal Size (1 1/2" to No. 4 ) Original Mass: Sieve Size Grams Retained % Grams Retained Cumulative % Retained Cumulative % Passing ASTM C33 Specification
Ballast/walkway aggregate shall be crushed stone broken by the crusher and have at least 2 broken surfaces: angular, roughsurfaced, clean and free of sand, loam, clay, flat, elongated, soft or disintegrated pieces, and other deleterious substances. 1. The Ballast/walkway aggregate shall conform requirements shown in the following table. to the ...
If crushed gravel is selected for use as aggregate base, it must be manufactured from material retained on the ½ inch ( mm) sieve. It must meet the gradation and physical requirements shown in At times, this material is missing some fine material and can become unstable. Crushed Air Cooled Blast Furnace Slag Used as 304
Gradation of stone and rock is found by ASTM C136, the Test Method for Sieve Analysis of Fine and Coarse . Evaluation of aggregate particle shapes through multiple crush . A good analogy would be to describe the gradation of an ASTM #57 stone by giving only the . 11 compares the weighted average of all three stages of crushing .
Ballast should satisfy the following size and gradation: a) Retained on 65mm sieve 5% Maximum . b) Retained on 40mm sieve* 40%60% . c) Retained on 20mm sieve Not less than 98% for machine crushed . Not less than 95% for hand broken * For machine crushed ballast only. Oversize ballast

Sieve analysis presents particle size information in the form of an S – curve of cumulative mass retained on each sieve versus the sieve mesh size. The most commonly used metrics when describing particle size distributions are DValues (D10, D50 D90) which are the intercepts for 10%, 50% and 90% of the cumulative mass.
C13605 Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates ... As surprising as it may seem, there are regional shortages of naturally occurring stone suitable for roofing ballast. Seems a lot of the good stuff is already up on top of other roofs. Robert E. .
Sieve analysis determines the gradation or distribution of aggregate particle sizes within a given sample. Accurate determination of material smaller than 75 µm (No. 200) cannot be made with

defined as the ratio of the total mass passing bar sieve slots, which are of the sieve size, to the total mass of aggregate retained on three specific sieve sizes. Mathematically, the flakiness index (FI) of a ballast material can be represented as follows: ⎟⎟×100 ⎠ ⎞ ⎜⎜ ⎝ ⎛ = T p M M FI (5) where, M p = total mass of aggregate passing a bar sieve slots; M
Determination of Fineness Modulus of Coarse Aggregates. To find fineness modulus we need to perform sieve analysis and for that above mentioned sieve sizes, mechanical shaker and digital weigh scale are required. Sample preparation. Take a sample of coarse aggregate in pan and placed it in dry oven at a temperature of 100 – 110 o C. After drying take the sample weight to nearest gram.
Sieve Analysis Test: Sieve analysis (or gradation test) is to assess the particle size and distribution of granular material. Often times referred to as, "Screening of material". Often times referred to as, "Screening of material".
Laboratory Test Sieves. The wellproven RETSCH test sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to meshspecific requirements, the fabric of each test sieve is precisely joined into the frame and tautened. The individual laser engraving of each test sieve provides...
Sieve Analysis Lab Report Discussion Conclusion The experiments described in this paper were undertaken primarily for the purpose of measuring the quality of work done in screening and sorting in American concentratingmills for Prof. Richards' work on OreDressing .
analysis is an area gradation. Therefore, some discrepancy between the sieve analysis and image analysis is expected. This discrepancy is calculated by averaging the difference at D 20, D 50 and D 80 of the gradation curves determined by the image analysis and sieve analysis using the following equation (e is the discrepancy): ¸¸ u100 ¹
Sieve analysis Wikipedia A sieve analysis can be performed on any type of nonorganic or organic granular materials including sands, crushed rock, clays, granite, feldspars, coal, soil, a wide range of manufactured powders, grain and seeds, down to a minimum size depending on the exact method.
B. Determine the grading of the ballast in accordance with ASTM C136/C136M. C. Ballast samples shall be obtained in accordance with ASTM D75/D75M.
