Modeling and analyzing autogenous shrinkage of hardening cement paste

In this paper, a conceptual model for analyzing the plastic part of autogenous deformation of cement paste based on the Arrhenius rate theory will be presented. The autogenous deformation will be calculated from the elastic deformations with inclusion of creep. Different kinds of cement paste with a water cement ratio 0.3 are tested and studied,...

Effect of the mix composition on rheological behavior of a fresh granular-cement paste material

In this paper, the effect of the mix composition on rheological behavior of a mixture is studied by considering a two-phase model for a mixture. A mixture is decomposed into a granular and a paste phase. Paste itself is divided into the void paste and the excess paste. The slump test is used for evaluation of rheological behavior of a mixture....
