Rheological behaviour of concrete with some supplementary cementitious material

  Concrete has often been called a liquid stone, before turning into artificial stone. This property of concrete gives it the ability to cast structural elements in every shape and size. Due to this property, only concrete gives architect and engineers the freedom to shape buildings and other structures at their will. This property of concrete is known as workability or more correctly, rheology. Rheology of concrete affects the efforts needed to transport and place concrete in different shapes and locations. With more and more mechanised constructions, the pumping of concrete has become practice at common place, hence increased importance of rheological properties. Supplementary cementitious materials, like fly ash, silica fume, ground granulated blast furnace slag, which are regularly used in concrete, modifies the rheology of concrete to a significant extent. This paper studies the effect of some of the these materials on rheological behaviour of concrete.
