Ultra high performance fibre reinforced concrete (UHPFRC) is a new construction material with superior of high strength and durability when compared to normal concrete (1). The composition of UHPFRC differs greatly to that of high strength and normal concrete; in particular it has a high cement and fine aggregate content but no coarse aggregate, a low water cement ratio, a high silica fume content and the addition of steel fibres (1-3). Determination of the mechanical properties using conventional testing methods has been the subject of a number of studies and guidelines (1,4-7). One potential method of testing is the nondestructive testing technique, which has been used in the past to study the elastic properties of conventional concrete but there are very few accounts of its application for UHPFRC (8,9). Non-destructive testing methods have been used to estimate the quality and to measure the mechanical properties of concrete structure without relying on test specimens, which are not necessarily representative of in situ structural concrete.
