Aggregate

The foundation of WGLS was built around soil and aggregate testing. Our testing meets Australian Standard Specifications as well as State Road Authority Specifications.

Aggregate materials form the basis of a range of products. Our assessments of these aggregates can greatly influence the end quality of these products.

Our In-House NATA Accredited Services for Aggregate Include:

Bulk Density / Particle Density Water Absorption
Particle Size Analysis / Particle Shape
Sodium Sulphate Soundness / Accelerated Soundness
Los Angeles Abrasion
Aggregate Crushing Value / Wet Dry Strength Variation
Clay Fine Silt / Organic /Weak Particles

In conjunction with ARC Laboratory Services:

Light Particles / Visual Comparison / Sugar / Methylene Blue
Aggregate Resistance to Stripping
Wear by Attrition
Polished Aggregate Friction Value
Accelerated Mortar Bar – Alkali Silica Reactivity
Degradation Factor
Aggregate Chloride and Sulphate
