Zusammenfassung:	PURPOSE: A flush type smart sensor for estimating the strength of concrete by using a guided wave measurement is provided to protect the sensor from external impact when burying the sensor into concrete and to efficiently measure guided wave signals by providing a transmitting passage of guided waves. CONSTITUTION: A flush type smart sensor for estimating the strength of concrete by using a guided wave measurement comprises a body(110), a guided wave transmitting terminal(120), and a guided wave receiving terminal(130). The body is formed in to a plate form of a steel material and comprises a pair of discharging holes, thereby providing a transmitting passage of guided waves. The guided wave transmitting terminal receives frequency signals input from outside, thereby generating guided waves and transmitting the same to a concrete structure. The guided wave receiving terminal receives reflective waves reflected from the concrete structure and transmitted from the body, thereby outputting to outside.
