Sprayed Concrete – Possibilities of Testing Sprayed Concrete Prepared in Laboratory

Abstract:

Sprayed concrete is widely applied thanks to current development of road and underground building industry. Selection of input materials, design, preparation and testing of sprayed concrete is relatively expensive because spraying machinery has to be used for application. The paper focuses on possibilities of manufacture and testing of sprayed concrete prepared in common laboratory mixer and compacted by vibration combined with defined level of pressure. This approach seems to be an alternative for initial design and testing of sprayed concrete prepared by machinery equipment.
