Analytical Study on Deformation of Fresh Concrete
Publication: Journal of Engineering Mechanics
Volume 115, Issue 3
Abstract
A simulation method of the behavior of fresh concrete is proposed in the present paper. To estimate the flow and deformation of fresh concrete, a method of viscoplastic finite element analysis is applied, in which fresh concrete is treated as a kind of Bingham model. In the analysis, slipping resistance between boundary surface and fresh concrete can be considered, and the dynamic behavior can be analyzed by calculation of the retardation of velocity change. In this paper, some analytical results for the slump test and the flow test are shown and discussed. The relationship between rheological constants and the values measured by the slump test and the flow test are clarified analytically, and the method for estimating rheological constants from the slump value and the flow value is proposed. Then, the adequacy of the analytical method proposed is examined by comparison with experimental results.
