Concrete Testing

lab_cubes2Our in-house laboratories are equipped to provide an extensive range of concrete testing and related materials testing services which meet the appropriate British and European Standards.

Typical testing includes compressive strength of concrete cubes and cores, as well as bricks and blocks.

Other testing includes mortar mix proportions and other related chemical tests.

We provide an on-site service to facilitate the sampling and making of concrete test cubes as well as a collection service. All cubes are appropriately cured in readiness for testing at our laboratory.

Working with our specialist field staff we also are able to undertake sampling (coring and dust drilling) and inspection concrete structures together with subsequent laboratory testing.

Our laboratory also provides chemical testing to assess the risk of attack on buried concrete from aggressive ground conditions arising from sulphates and/or acidic soil as outlined in the BRE SD1 guidance document. Additional technical advice and assistance is also available from our team of professional geotechnical and civil engineers.

Concrete Cube Compressive Strength BS EN 12390-3 Determines the strength of hardened 100 – 150mm concrete cubes usually at 7, 14 and 28 days after casting. Used as quality control during construction of concrete structures.
Concrete Core Compressive Strength BS EN 12504-1, 12390-3 & 12390-7 Used to assess the strength of concrete in existing structures.
Cement Content & Cement:Aggregate Ratio BS1881-124 Used to determine the proportions of aggregate and cement  hardened concrete.
‘Oxine’ Test for presence Hi-Alumina Cement (HAC) BRE IS 15/74 Concrete containing hi-alumina cements have been known to weaken over time. This test determines whether it is present.
Compressive strength of Bricks or Blocks BS EN 771-3 & 772-1 Used to determine the strength of masonry units such as concrete blocks and clay bricks.
Mortar Mix Proportions BS4551 Used to determine the proportions of sand, cement and lime in hardened mortar.
Depth of Carbonation (by Phenolpthalein indicator) BRE IP 6/81 This test is used to establish whether the pH of concrete has reduced. A lower pH can allow corrosion of reinforcement.
Sulphate Content BS1881-124 Used to assess whether concrete in a structure is likely to have been attacked by sulphates.
Chloride Content BS1881-124 Used to assess whether concrete in a structure is likely to have been attacked by chlorides.
