In response to our client’s needs, we have set up our first mobile laboratory unit in 2004. This additional flexibility allows us to offer a convenient, personalized, complete service package, from sampling to data delivery. All equipment in our mobile laboratory are always kept calibrated and ready to go.

Advantages of Our Mobile Laboratory

• Cost Saving: 
  Reduces the cost of mobilization as field teams are brought to the site.
• High Quality Data: 
  We deliver the same quality of service as our fixed laboratory facility but in less time and for a lower cost.
• Customized data delivery:
  Pre-Project planning assistance.
• Dedicated: 
  Unlike fixed laboratories, our mobile laboratory concentrate only on your project alone and are always at your disposal for questions or concerns.
• Flexibility: 
  Our Mobile laboratory allow you to Re-prioritize samples based upon previous results.
  
  

PARTICLE SIZE DISTRIBUTION

This test method covers the determination of percentile quantity of particles of known diameter within a sample. The specimen can be either passed through a set of standard sieves in its natural state, or if a significant amount of binding material is present, such as clay, then the sample can first be washed over a small aperture sieve to remove the binding materials

Particle Size Distribution

CRUSHING VALUE

This test is a measure of the strength of aggregate, which will normally to be used in making concrete. It involves standard compression of 400kN in a mould of a known mass of aggregate of single particle size and measuring resulting percentage of crushed particles.

10% FINES

This test is a measure of the strength of aggregate, which will normally be used in making concrete. It involves compression in a mould of a known mass of aggregate of single particle size and measuring the load required to reduce 10% of the particles to fine material.

FLAKINESS AND ELONGATION

These tests are used to determine the percentage of unsuitably shaped particles for aggregate to be used in concrete. Aggregate particles are classified as flaky when they have a thickness of less than 0.6 of their mean sieve size, and are classified as elongated when they have a length of more than 1.8 of their mean sieve size. The index for each type of particle is found by separating the particles and expressing their mass as a percentage of the mass of the sample tested.

IMPACT VALUE

This test is a measure of the strength of aggregate, which will normally to be used in making concrete. It involves standard blows 15times in a mould of a known mass of aggregate of single particle size and measuring resulting percentage of crushed particles.

CLAY SILT AND DUST

This test is used to derive the percentage by mass of clay, silt and dust in aggregates, which are to be used for making concrete. The method involves weighing the specimen, then removing such material by wash sieving, followed by re-weighing the sample.
Limiting values of clay, silt and dust content are normally included in concrete specifications to avoid their deleterious properties on concrete.

CORING 100MM DIAMETER

Often, existing concrete structures will need to examined and tested to ensure the concrete remains of adequate strength and durability. Extraction of concrete cores, achieved by rotary drilling using a diamond tipped hollow barrel, serve as a means of taking a sample of concrete which can then be used to determine various physical properties, but most commonly compressive strength.
