Certification of materials and products
The quality and durability of a concrete structure is vitally important. For one thing, the renovation or replacement of buildings and installations can be very costly. What is more, concrete structures have to meet exacting safety requirements. So it is crucial to know whether materials meet the relevant criteria. And, if they fail, to find out why. KEMA’s Residual Materials and Building Quality Laboratory can provide the answers to questions such as these.
KEMA has its own STERLAB-accredited concrete laboratory, where all manner of questions relating to the behavior and properties of concrete and similar materials and products can be investigated. The lab is the first in the Netherlands to be accredited under NEN-EN-ISO/IEC 17025:2000. Our expert technicians specialize in the testing of building products and the raw materials used in their manufacture, such as fly ash, waste incineration slag, sand and grit, cement, repair mortars, impervious structures and concrete paving blocks and tiles.
Mechanical properties can be examined using a special rig capable of performing bending tests, fission tests, tensile tests and compression tests on concrete test pieces with loads of up to three thousand kilonewtons. In addition, there is an integrated bending, tensile and compression test rig capable of applying up to three hundred kilonewtons. Facilities are also available for testing the elasticity modulus of a sample. A wide range of physical tests can be performed as well, including water penetration tests for impervious structures, based on standards such as CUR63, ISO DIS 7031 and many others. Mercury porosimetry analyses are used to determine pore volume and pore size distribution in ceramic materials, while numerous other techniques are available for determining the physical properties of process residues, waste substances and raw materials used in the manufacture of building products.
KEMA also works as an independent verification laboratory for various external certification bodies, including BMC and KIWA.
