MATERIALS TESTING

Chemical

Ensuring the quality of aggregate for roadworks and concrete.

Our accredited facilities perform all manner of chemical testing for aggregates.

Our tests always adhere to standards set by SANS, ASTM and British Standards.

SERVICE OFFERING

01


Organic Impurities

This test is done to determine the short-term retardation and long-term deleterious effects of organic impurities.

02


Chloride Content

Specifies the determination of the chloride content in aggregates which can have a negative binding effect in some construction applications.

03


Water Soluble Salt Content

This standard specifies a method for determining the total water-soluble salt content of fine aggregates and of fines in aggregates for base courses. Water-soluble salts can be detrimental to roads, concrete and stabilized foundations for paved areas.

04


Deleterious Clay Content

This method determines whether the clay content of the fines of an aggregate contains deleterious swelling or active clay minerals which are usually resultant from weathering of rock.

05


Initial Stabilizer Content

Determines the percentage of stabilizer that will first be absorbed by the material to neutralize acidity levels before stabilizing will take effect.

06


Moisture in Asphalt

Used to determine the percentage moisture in a freshly mixed hot mix asphalt (HMA) mix.

07


Plasticity index Hydrometer test

To determine the particle size distribution of materials to detail the silt and clay percentages, especially of material smaller than 2mm.

08


Rock Durability Using 10% FACT

Used to determine the strength of the aggregate sample after it has been exposed to ethylene glycol that acts like a weathering agent.

09


Back-titration

To determine the percentage of stabilizer added during the construction phase to see if the design was adhered to and if proper mixing was achieved on site.

10


Particle & Relative Density

To define the weight or density of a material.

11


Methylene Blue

Determines whether the clay content of the fines of an aggregate contains deleterious swelling clay minerals which could adversely affect the quality of the asphalt mix.
