Abstract
An experimental study was conducted to investigate the feasibility of using ultrasonic waves to detect the basic properties of Portland cement concrete (PCC). The experimental programme was initiated to investigate the effect of water-cement ratio (w/c), aggregate type, air entrainment, and curing time on measured ultrasonic wave velocity and signal energy. Three w/c ratios (0.35, 0.45 and 0.55) were evaluated. Two aggregate types (quartzite and limestone) were included in the PCC mixes separately. Mixes were prepared as non-air entrained and with air entrainment. Thus, a total of twelve batches were prepared. Ultrasonic measurements were performed on 7.5 x 10 x 40 cm PCC specimens at 1, 3, 7, 14, 21, and 28 days of moist curing using direct and indirect measuring methods. Ultrasonic waves were used at two frequencies, 54 and 340 kHz. Collected data was analysed based on ultrasonic wave velocity and signal energy.
