Chemical Analyses Of Construction Materials
Construction materials, especially concrete products, are subject to ongoing inspection in order to ensure safety in manufacturing and the highest-quality end product. This requires analysis of the raw materials (sand, gravel, grit, recycled material) in terms of chemical parameters and the determination of physical and chemical characteristics for quality control.
In existing constructions, inspection of the construction materials used ensures stability and longevity.
We test raw materials and aggregates (gravel, grit, sand, recycled material) against chemical parameters that can influence the quality of the concrete:
Acid-soluble sulphate and chloride, total sulphur content, water-soluble sulphate and chloride, pH-value, Essai de ganulates Déterminationdes alcalins solubles dans l’eau de chaux (LPC 37/ French standard), lime content
- Testing of mixing water in concrete production.
- Analysis of acid-soluble chloride from drilling dust samples to monitor existing structures
- Testing of the materials used / aggregates against a potassium permanganate index
- Further testing in the construction of concrete drinking water facilities.
Tailored chemical and physico-chemical analyses to suit the customer’s needs: Primary components, secondary components, trace elements.
