Abstract. Recently, the cost of road repairs increases every year because of an early-age distresses and the fact that the quality of the concrete mixtures produced in a batch plants are not stable. A stable quality control of cement concrete mixtures is very important in construction site. This paper de-scribes the development of quality control equipment and technology using Internet of Things (IoT) technology. Additionally, a database management system (DBMS) was utilized in order to increase the usability and accessi-bility of data. A QR code was adopted to the ready-mixed concrete delivery system from a batch plant to a job site, enabling the data to be cached at a glance. A rheological properties of concrete mixture was investigated through a Twin Shaft Rheometer Mixer, which enables the analysis of con-crete rheological properties. In addition, the quality control of concrete pavement was carried out at a job site using a unit water quantity tester and a chloride content tester, which enables transmitting the measured data at a job site in real time through the Bluetooth reception function. As a result, this research could lead to the development of equipment incorporating IoT-based Quality Control system. Moreover, the development equipment yields more precise data in real time compared to the existing equipment.
