INFLUENCE OF AGGREGATE VOLUME CONCENTRATION UPON THE WORKABILITY OF CONCRETE AND SOME PREDICTIONS FROM THE VISCOSITY-ELASTICITY ANALOGY

A simple theoretical approach is used to obtain rheological equations for concrete. It is assumed that the cement-paste phase approximates to either a Newtonian fluid or a Bingham body. The approach used predicts that changes in aggregate volume concentration give rise to large changes in fluid viscosity, yield value and plastic viscosity. It is shown indirectly by using the viscosity-elasticity analogy that the resulting equations are in good agreement with experimental results on concrete. /Author/TRRL/
