Abstract: High strength and durability are the key factors determining the quality of concrete. To achieve the required properties, concrete mix design, and early age hydration, are the main factors affecting the performance of concrete. It is essential to monitor fresh concrete continuously through non-destructive techniques at the moment of mixing. In this study, acoustic emission (AE) has been applied to allow a continuous monitoring of the fresh cement paste. This non-destructive inspection allows the estimation of concrete properties by capturing elastic waves that are nucleated and propagate in the cement past. Moreover, ultrasonic pulse velocity (UPV), capillary pressure and heat evolution monitoring has been applied on cement paste to study the process of hydration mechanism. This study aims to check the sensitivity and effectiveness of AE technique to characterize the ongoing processes in fresh cementitious material and the possibility to contribute to a better monitoring of the process as an additional tool.
