Standard EN SampleTesting Concrete: Recommendations for the Measurement of Dynamic Modulus of Elasticity
Also Known As:
BS 1881-209:1990 is a standard that provides recommendations for measuring the dynamic modulus of elasticity in concrete. The standard outlines a procedure that involves using longitudinal vibrations of laboratory specimens to determine the dynamic modulus. The objective of this test is to assess the ability of concrete to withstand dynamic loads and vibrations.
The standard specifies the necessary equipment and instrumentation required to measure the dynamic modulus accurately. It provides guidelines on the preparation of laboratory specimens, including their size and shape, as well as the types of transducers and sensors to be used during the test.
The procedure involves subjecting the concrete specimen to longitudinal vibrations within a controlled frequency range. The dynamic modulus is then determined by measuring the resonance frequency and mode shape of the specimen using appropriate measuring techniques and equipment. The standard also provides guidelines on data interpretation and reporting.
