Abstract :
Expanded polystyrene (EPS) concrete is a new lightweight building material that exhibits good mechanical properties and a priori mechanical features that are suitable for the construction industry. The mechanical properties of EPS concrete were determined to be related to the concrete matrix and particle size of EPS. The compressive strength, tensile strength and flexural strength of EPS concrete with different size of EPS particles were compared in this paper. Based on the results of the compressive strength tests, a compressive strength expression was proposed. Ultrasonic testing was performed during the processes of loading up to uniaxial compressive failure. The ultrasonic testing results indicated that the mechanical properties of EPS concrete are related to the EPS particle size and the granules content and that the ultrasonic testing method can detect damage of EPS concrete during the loading process.
