The purpose of the study is to provide reliable data on high-strength recycled aggregate concrete and basic data for maintaining a structur e built with high-quality recycled aggregates. An experimental concrete structure mould with rectangular parallelepiped dimensions of 600 x 6 00 x 200 mm, is prepared to measure the wave velocity of specimens aged 28 days. The ultrasonic pulse velocity was measured for specimens that were aged for 1, 3, 7 and 28 days. In the compressive strength test at a material age of 28 days, the concrete incorporating recycled aggregates show almost the same or slightly lower strength com pared with natural aggregate concrete. Using the variables of optimi sed contact time, the velocity of the compression wave obtained th rough simulation can be an index to determine non-destructive test reliability and evaluate the applicability.
