This paper presents the results of the investigation on the fundamental differences in the
viscoelasticity between alkali-activated fly ash/slag materials (AAMs) and cement pastes …

Assessment of viscosity is important for development of new concrete technologies. In this
study, the effect of particle size and type of supplementary cementitious materials (SCM) and …

The objective of this study was to investigate whether cementitious materials undergo
changes during pumping processes due to pressure variation. The influence of pressure on …

A better fit to rheological measurement of cement pastes is only part of model selection. The
selected models are likely to describe the rheological behavior of cement paste, but they …

A precise measurement of the rheological properties of concrete is the first step to
quantitatively evaluate the placing and casting process. Both yield stress and plastic …

Workability is regarded as one of the important parameters of high-performance concrete
and monitoring it is essential in concrete quality management at construction sites. The …

With the increasing use of preplaced aggregate concrete in construction, the grout filling in
preplaced aggregate concrete is important for ensuring proper consolidation and high …

The addition of polycarboxylate based surfactants cause particles dispersion in cementitious
materials and enhances their fluidity. The polymeric structures of the polycarboxylates have …

Rheology of concrete allows us to understand the flow behavior of concrete and further
extend the quantitative evaluation of its construction performance. The use of a concrete …

Ultra high performance cementitious materials possess high solid volume fraction by a
decreased water-to-binder ratio. The use of a high-range water reducing admixture allowed …
