Concrete Admixture
The performance and characteristics of fibre-reinforced concrete need to be tested with methods tailored to suit the specific end application, to make sure it can be used safely in future specifications. These test methods are now fully-standardised internationally through the European Standards (EN), as well as the American Society for Testing and Materials (ASTM).
