More About Me

Aggregate Testing

Aggregate tests

The process is divided in various jobs that include: Physical: Grading, Shape, Relative Density, Bulk Density, Water Absorption
Mechanical: AAV, Wet Attrition
Durability: Sulphate Soundness, Frost Heave, Slake Durability Index, Methylene Blue, Drying Shrinkage
Chemical: Organic Matter, Chloride, Sulphate or full analysis
Specialist: AAR Assessment using Petrography, Chemical Test, Mortar Bar and Accelerated Mortar Bar and Concrete Prism Met

Soil Testing

soil tests

By examining different textures of soil, we can test the various qualities
Moisture – Density Relations
Sand Equivalent Value of Soils and Fine Aggregates
Particle Size Analysis of Soils
California Bearing Ratio, advice on testing and more

Nuclear Density

nuclear density tests

By using the machine, we examine the quanity of the moisture and the inner structure of the test material
Moisture – Density Relations
Field Moisture and Density tests are done with high precision and know-how

Concrete Testing

concrete tests

Testing concrete is vital for various reasons
Evaluating new material and products used to make concrete.
Checking complaince before, during and after construction.
As concrete age, we investigate its failing conditions to avoid accidents at all stages of a construction

Cement/Slump Testing

slump tests

Slump tests may include the following
Density and fineness
Compressive strengths
Setting times and soundness
Checking complaince before, during and after construction.
Depending on clients needs, celemet/slump Chemical testing will be conducted by technicians for thorough results

Clay Testing

slump tests

One of the non-hard ways to test, analyze and for production. Types of tests iniclude:
Roll Compaction
Briquetting
Coating
Moisture Content
Agglomeration
Palletizing
Drying and High Temperature Thermal Processing just to name a few

Clay Soil - Ring Testing

slump tests

One of the non-hard ways to test, analyze and for production. Types of tests iniclude:
Roll Compaction
Briquetting
Coating
Moisture Content
Agglomeration
Palletizing
Drying and High Temperature Thermal Processing just to name a few

Bitumen Testing

slump tests

Also know as Bitumen Penetration testing,examine the consistency of a sample of bitumen
by determining the distance in tenths of a millimetre
that a standard needle vertically penetrates the bitumen specimen under known conditions of loading, time and temperature.
This is the most widely used method of measuring the consistency of a bituminous material at a given temperature.
It is a means of classification rather than a measure of quality.


Simply put, We measure the hardness or softness of bitumen by measuring the depth in tenths of a millimeter
to which a standard loaded needle will penetrate vertically in 5 seconds.
