Fresh Concrete Pumping Arrest Investigation for Thixotropy

Aug 25, 2019 · After an introduction to fresh concrete rheology and numerical modelling, ten representative thixotropy cases are analysed. Despite some unresolved numerical instabilities, the numerical framework allows to estimate pumping pressure peaks after resting time.

pumping operation can be a very challenging task. This paper reports on a large-scale concrete pump test on a construction site, specifically focusing on the risk of thixotropy. Fresh concrete has been pumped in a horizontal closed-loop pumping pipe with a total length of 600 meter. In steady-state pumping conditions, the pumping operation was very

Numerical method for thixotropic behavior of fresh concrete

Oct 30, 2018 · Oct 30, 2018 · The thixotropic behavior greatly influences the workability and the construction quality of concrete, such as flow ability decline during waiting to pump, slump loss even re-mixing in agitator truck before pumping, fluidity gain under a vibration in mould, change of formwork pressure, collapse in 3D concrete printing, and weak concrete joint .

Why is fresh self-compacting concrete shear thickening

Jun 01, 2009 · 1. Introduction. Concrete is described by rheologists as one of the most difficult materials to study. Nevertheless, the rheological properties of fresh concrete have been studied extensively in literature, showing that concrete is a thixotropic material,,, having a yield stress and a plastic viscosity,,, and that time influences these properties due to hydration .
