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 ...

Abstract: This paper deals with the time dependence of fluidity and thixotropy of high fluidity concrete containing polycarboxylate-based superplasticizer. Taking the effects of both hydration and physical flocculation of cement ...

Abstract: In this paper a particle assembly model was proposed for high fluidity concrete in the fresh state. This particle assembly is composed of cohesionless particles (aggregates grains) and cohesive particles (cement grains) ...

Abstract: This paper presents a microscopic approach to model the yield condition of high fluidity concrete in the fresh state for the rheological evaluation and the numerical flow simulation to optimize its workability and composition. ...
