Role in Rheology in Developing New Breeds of Concrete and Construction Techniques

This paper describes how with the increased use of self compacting concrete and other high performance concrete such as high strength concrete demands augmented knowledge of properties such as yield value and plastic viscosity of successful application of the product. For determination of these properties, rheology is a key tool. Application and benefits of rheology as a tool in evaluating the properties of fresh concrete, in particular self-compacting concrete are briefly discussed. A coaxial cylinder viscometer can be used to evaluate the rheological properties of fresh concrete. Several examples are shown concerning shift in parameters such as increased water content, air content, silica fume content and different dispersing admixtures. Rheology con inform (scientifically) where one is regarding the properties of the fresh concrete, where to go to optimize and how to get there. Often the alternative is just based on feeling.
