Segmental pavers breaking load
Breaking Load of Segmental Pavers testing measures a load-bearing capacity in a bending application.
Masonry unit compressive strength
The Masonry Unit Compressive Strength test assesses the load-bearing capacity of masonry wall units or segmental pavers.
ITS (Indirect Tensile Strength)
An optimal binder level is established with an ITS test, indicating the overall strength of a blend.
Size and shape
Otherwise known as the ALD test, the size and shape test is used to define the average least dimension versus the average greatest dimension.
Weathering quality index
Categorises the aggregate into a number of different quality groups based on the resistance of the aggregate to cycles of wetting and drying.
Cleanness value
The Cleanness Value test measures the amount of fine clay-like material coating surfacing and concrete aggregates.
Particle size distribution (PSD)
Particle Size Distribution testing measures the amount of different sized particles in an aggregate product.
Sand equivalent
The Sand Equivalent test provides an empirical measure of the quality and quantity of fines in an aggregate.
Plasticity index (PI)
The Plasticity Index test is used to assess the quality of the fines in an aggregate.
Compression strength, drilled cores
Drilled cores of hardened concrete can be tested to assess strength and density.
Splitting tensile strength
Splitting Tensile Strength testing measures the amount of stress on the tension face of bending concrete.
Flexural tensile beams testing
Flexural Tensile Strength assesses concrete’s ability to resist bending.
Fresh concrete sampling
We can test ready-mix concrete from the plant, mixer truck or onsite skip units.
Grout cubes
To assess the compression strength of fine-grained cementitious grouts, we test cube samples.
Compression strength testing
The Compression Strength test measures the ability of the concrete to support loadings over a given area.
