Abstract:
The Western Australian School of Mines (WASM) has developed a state-of-the-art facility for the dynamic testing of full scale fibrecrete panels. A large scale punch test method has been developed to evaluate various mix designs at different curing times. The fibrecrete is sprayed on to a large sandstone or granite substrate containing an isolated 500 mm disc that is centrally located and used to simulate instability. The test sample is placed on to the sample frame and restrained on all sides. The disc is dynamically displaced and instruments measure the dynamic displacement and the load being applied to the sample through the loading disc. The force–displacement properties have been used to determine the dynamic energy absorbing capability of fibrecrete systems.
