Testo completoConcrete pumping process is important in the construction sector, facilitating the transport of fresh concrete to the casting site, even in difficult-to-access areas. This technique enables the achievement of considerable heights and distances. However, this process presents challenges. Therefore, accurately predicting the pumpability of concrete appears to be essential. Indeed, concrete pumpability relies on its rheological properties and its ability to form a lubrication layer (LL) during its flow through pipes. Accordingly, it is worthy to mention that mastering the rheology of concrete and understanding the characteristics of the LL is important, especially considering that the mechanisms of LL formation remain not well understood.This project focuses on investigating Reynolds dilatancy (RD), a potential mechanism involved in LL formation, and aims to highlight the key parameters governing it. The first part of the study introduces the development of a new method to assess shear-induced variations (RD) at free-surface flow. This method, although more reliable for conventional vibrated concrete (CVC), it does not fully explore this mechanism. Consequently, a new empirical device, the CRD-Test, was designed to evaluate the RD of self-compacting concrete (SCC) subjected to various scenarios under free-surface and pressurized conditions, simulating real casting and pumping processes. In this second part of the study, SCC is considered as a biphasic mixture of coarser particles (> 1.25 mm) in a fluid matrix of fine mortar (< 1.25 mm). Moreover, the new experimental device, named CRD-Test, offers wide range of shear and pressure levels. It is based on a modified coaxial cylinder tribometer, with a rotational speed ranging from 0 to 3 rps, and an air pressure regulator from 0 to 300 kPa. The RD phenomenon is manifested by fluctuations in lateral pressure measured at the outer cylinder of this apparatus and it was investigated through new indices.Experimental results reveal that RD values were found to be in good agreement with the workability and design parameters of the investigated concrete mixtures. Concrete with low fluidity values exhibited high RD indices under both free-surface and pressurized shear conditions. Furthermore, a biphasic approach highlights correlations between RD and the characteristics of aggregates with a diameter greater than 1.25 mm, as well as the viscoplastic characteristics of the fine mortar (i.e., the suspending phase). Moreover, RD results are mainly affected by the relative packing density of coarse aggregate during pumping process. Finally, Reynold values were in good agreement with flow regime characteristics, particle dynamics, and shear-induced particle migration indices. According to established correlations, dynamic segregation can significantly influence the mechanisms of LL formation during concrete pumping at low shear rates, illustrating the importance of Reynolds dilatancy in this process. However, at higher shear rates, dynamic segregation has been observed to negatively impact RD values, thereby increasing the risk of blockage during concrete pumping
