Sandberg offers a comprehensive range of cement testing encompassing both physical and chemical cement testing utilising BS, EN and ASTM methods. Due to our independence cement testing can be carried out as part of routine quality control for cement manufacturers or as part of a materials failure investigation.
Sandberg carries out a complete range of chemical testing on a wide variety of materials associated with the built environment. All chemical testing is carried out by Sandberg’s experienced technical staff operating from our well equipped UKAS accredited Laboratories. Chemical testing can be carried out using BS, EN and ASTM standards supplemented by our own UKAS accredited documented in-house methods.
Efflorescence is caused by soluble salts in building materials, or soluble salts transferred into building materials by water, being drawn towards a drying surface by the movement of water. Efflorescence can often result in damage caused by salt crystallisation leading to the breakdown of mortars and renders.
Infrared spectroscopy is a technique that can be used mainly qualitatively but occasionally quantitatively for identification of organic (and sometimes inorganic) substances. Each organic compound whether it be a simple compound, polymer or adhesive produces a characteristic spectrum when a beam of radiation from the infrared region of the electromagnetic spectrum is passed through it.
Chemical analysis can establish the composition of a leakage water sample at the time it was sampled, but it is possible that the chemical composition of the water sample could have been altered by contact with the ground or general building materials making it harder to determine the exact composition of the source water.
