Public test guide

Aggregate soundness

Accelerates repeated weathering action to assess whether aggregate is likely to break down under environmental exposure.

Plain-language explanation

What the test tells you.

The project specification controls the exact method and acceptance requirement.

01

What it is

Prepared aggregate is cycled through the specified chemical solution and drying process, then checked for loss.

02

What is used

Graded aggregate, specified solution, controlled containers, drying oven, sieves and balance.

03

What it determines

Mass loss or breakdown after the required number of cycles.

04

Why it matters

Supports durability selection for aggregate exposed to wetting, drying or other severe service conditions.

Typical test sequence

From sample
to result.

  1. 01

    Prepare the specified aggregate fractions

  2. 02

    Complete the required immersion and drying cycles

  3. 03

    Re-sieve, weigh loss and report soundness
