Prediction of lateral form pressure exerted by concrete at low casting rates (2015, methodology): “In the case of highlyflowable concrete at rest in formwork, under normal gravitational conditions, it has previously been reported that the lateral pressure (at the walls) could be less than hydrostatic pressure since some shear stress is supported by the walls [1, 6, 11].”
Rheology of fresh concrete: from measurements to predictions of casting processes (2007, background): “This is true for many materials [40] and seems true for concretes [5, 12 ].”
A thixotropy model for fresh fluid concretes: Theory, validation and applications (2006, methodology): “This is true for many materials [28] and seems true for concretes [2,26].”
Properties of fresh and hardened concrete (2011, background): “However, it was recently demonstrated that, in the case of modern fluid concretes such as SCC, the thixotropic behavior of the material plays a major role [72–76].”
Computational modeling of concrete flow: General overview (2007, methodology): “[10] Roussel, N., Staquet, S., D’Aloia Schwarzentruber, L., Le Roy, R., Toutlemonde, F., SCC casting prediction for the realization of prototype VHPC-precambered composite beams, Accepted for publication in RILEM Materials and Structures.”
Structural built-up of cement-based materials used for 3D-printing extrusion techniques (2016, background): “For instance, formwork pressure reduction or distinct-layer casting issues can be predicted using the structural build-up rate of self-compacting concrete [21–24].”
Rate of thixotropic rebuilding of cement pastes modified with highly purified attapulgite clays (2013, unknown): “Therefore many studies have explored methods to tie the rheological behavior of SCC to formwork pressure response and strategies to reduce SCC formwork pressure through mix design [1–4].”
Use of creep recovery protocol to measure static yield stress and structural rebuilding of fresh cement pastes (2016, methodology): “As modeled by Ovarlez and Roussel [11], the higher the Athix, the lower the formwork pressure.”
