Detailed Step-by-Step Explanation of How the Test is Conducted

The ASTM D2489 standard provides a method for estimating the surface area of aggregate particles. The test involves several steps:

1. Sample preparation: The aggregate sample is prepared according to the relevant standards.

2. Measurement of particle size distribution: The particle size distribution of the aggregate is measured using a sieve analysis or other suitable methods.

3. Calculation of surface area: The surface area of the aggregate particles is calculated based on the particle size distribution.

Calculation of Surface Area

The surface area of the aggregate particles is calculated using the following formula:

Surface area (SA) (Dp2 - Di2) / 4

Where Dp is the diameter of the particle and Di is the diameter of the sieve opening.

Measurement of Particle Size Distribution

The measurement of particle size distribution involves several steps, including:

1. Sieve analysis: The aggregate sample is passed through a series of sieves with different mesh sizes.

2. Calculation of cumulative percentage passing: The cumulative percentage passing is calculated for each sieve size.

3. Plotting of particle size distribution curve: The particle size distribution curve is plotted based on the cumulative percentage passing.

Calculation of Surface Area

The surface area of the aggregate particles is calculated based on the particle size distribution curve. The calculation involves several steps, including:

1. Calculation of the surface area of each particle size range

2. Calculation of the total surface area

Measurement and Calculation of Surface Area

Eurolab uses advanced equipment and software to measure and calculate the surface area of aggregate particles according to the ASTM D2489 standard.
