Sandberg Remains Open During This Challenging Time

Whilst many of our staff are working from home during these unprecedented times, all our activities remain open for business in line with government guidelines.  We have adjusted our operations so that staff remain safe.  Currently, although we are working at a reduced capacity, we are meeting client demands and are welcoming new enquiries.

Concrete testing is one of Sandberg’s core activities but it encompasses so much more than simple cube testing.

WHY Test Concrete?

Concrete testing is carried out for many reasons:

  • Evaluation new materials or products
  • Check compliance before, during or after construction
  • Assess condition for change of use or service life prediction
  • Failure investigation

WHAT Can Be Tested?

Concrete testing means more than cubes or cores:

  • Component materials; cement, pfa, ggbs, admixtures, coarse and fine aggregates, fibres, reinforcement, water
  • Fresh Concrete, mortar and grout
  • Hardened Concrete; cast specimens : cubes , cylinders, prisms
  • Existing structures; drilled core or dust samples, sawn specimens, insitu non-destructive testing of structural members

WHICH Tests?

Concrete testing is loosely covered by four main headings:

  • Physical/Mechanical
    • Workability/Consistency
    • Compressive/flexural/tensile strength
    • Modulus of elasticity
    • Density/water absorption/permeability
    • Moisture/thermal movement
  • Chemical
    • Composition (cement content, w/c ratio)
    • Presence of contaminants, eg chlorides
  • Visual and Microscopical Examination
    • Identification of components
    • Identification of deterioration processes
  • Durability
    • Soundness
    • Bond strength/adhesion
    • Cover to reinforcing steel
    • Carbonation depth

WHO should test?

Concrete testing is best carried out by someone that is:

  • Experienced in planning, concrete testing and interpretation of test data
  • Independent to avoid bias (no matter how unintentional)
  • Accredited for a wide range of tests

Sandberg meet this criteria and offers a range of concrete testing services which can be tailored to suite your needs.
