Aggregates
Our team is equipped to assist with projects that necessitate unconventional testing methods. As a NATA-accredited laboratory, we offer a diverse array of tests compliant with AS 1141 and TfNSW standards. Trust us to deliver precise and reliable results tailored to specific needs.
AS 1141.3.1
Sampling and Testing Aggregates
From the Scope:
Defines the requirements and specifies methods for:
a) Taking samples of course and fine aggregates;
b) subdividing samples; and
c) packing and forwarding samples for examination and testing.
AS 1141.11.1
Particle Size Distribution
From the Scope:
The Method for the determination of particle size distribution is course and fine aggregates by sieving.
AS 1141.12
Materials finer than 75um in aggregates (by washing)
From the Scope:
The method for the determination of the amount of material finer than 75um in aggregate, by washing.
AS 1141.32
Weak Particles (including clay lumps, soft and friable particles) in coarse aggregates.
From the Scope:
The method for determining the percentage of weak particles in coarse aggregates.
AS1141.33
Clay and fine silt (settling method)
From the Scope:
Describes a settling test which may be used in the field or laboratory as a guide to the amount of fine silt, clay and similar materials in fine aggregates.
AS1141.34
Organic Impurities other than Sugar
From the Scope:
Sets out a method for an approximate determination of the presence of organic materials, other than sugar, present in fine aggregate.
TfNSW TS 02799.02Particle Distribution of Aggregates (by washing)
From the Scope:
This test method sets out the procedure for determining the particle size distribution of aggregates by sieve analysis after washing with water.
TfNSW TS 02799.04Particle distribution of aggregates finer than 75 um (by Washing)
From the Scope:
The test method sets out the procedure for determining particle size in aggregates finer than 75 um by washing.
