2. Concrete rheology

This chapter describes modelling and experiments on the rheology of cement- based materials. The rheology of concrete is a difficult problem, as fluid cement paste is non-Newtonian by itself, and concrete has the added complication of many sand and rock inclusions. However, the processing of concrete is controlled by its rheological properties, which must be evaluated scientifically in order for real predictability to be achieved.



This section is a review of measurement methods and nomenclature. It includes state of the art reports on rheological measurements on cementitious materials (concrete, mortar and cement paste). It also give definition that relate to concrete rheology.

Interaction of Supplementary cementitious materials (SCM) and/or chemical admixtures: this section is related to the influence of the SCM and chemical admixtures on the flow properties of cement paste or mortar. Potentially leading to prediction of their influence on concrete.
