ASTM C136 - Sieve Analysis of Aggregates

Applies to QEST Web App

This article describes how to use the ASTM C136 - Sieve Analysis worksheet, which is based on ASTM C136.

QestID: 110431

Contents

Overview

The ASTM C136 - Sieve Analysis of Aggregates worksheet can be used to determine the particle size distribution of fine and coarse aggregates. It is based on the methodology of the ASTM Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates (C136/C136M).

The standard structure and functionality of this worksheet is described in the article Particle Size Distribution by Sieving Tests and its related articles. This article focuses on those parts of the worksheet where the functionality varies from, or is additional to, the standard functionality.

Together, these articles provide information on how the various choices available within the QEST Web App version of this test method provide the required pathways to deal with the variations within the test.

  • This worksheet contains a wide grid for some results.

  • When using tablet devices, landscape orientation will allow more of the grid to be shown at once.

This worksheet has no departures from the standard functionality, for this section.

Specimen Preparation

Section Functionality

Standard functionality is described in these places:

Additional functionality and variations specific to this worksheet are described below.

  • Material Washed

Material Washed

This functionality is essentially the same as for the standard Sieve Analysis Specimen Preparation, Received Sample Condition, Nominal Particle Size, Timing of Drying, Timing of Washing | Timing of Washing .

The difference is that instead of having an in-built Washing section, this worksheet uses an embedded version of ASTM C117 to implement the washing process.

Selecting a washing option causes the embedded test to be added to the worksheet.

Additional Results

The following calculated results are normally reported, if all requirements are met:

  • Percentile Values - D10, D15, D30, D50, D60, D85:

  • Coefficient of Uniformity (Cu);

  • Coefficient of Curvature (Cc).

Optional Results

The following value is normally available for optional reporting, if all requirements are met:

  • Fineness Modulus (Fm).

Equipment

For equipment to be available for selection in equipment drop down boxes, the equipment item must first be created in QESTLab's Equipment list.  Refer to article https://spectraqest.atlassian.net/wiki/spaces/QP57/pages/3591262999 .

The following equipment can be selected on the worksheet:
