Rheology control of limestone calcined clay cement pastes by modifying the content of fine-grained metakaolin

Limestone-calcined clay-cement (LC3), as one of the most promising sustainable cements, has been under development over the past decade. However, many uncertainties remain regarding its rheological behaviors, such as the metakaolin content of calcined clay. This study aims to investigate the effect of increasing the content of fine-grained...

Predicting the yield stress of 3D printing mortar based on the flowability of paste and excess paste thickness

This paper develops an empirical model to predict the static yield stress of 3D printing mortar based on the flowability of paste and excess paste thickness. The components of the mortar are divided into paste and aggregate. The relation between the yield stress of mortar and the yield stress of paste and the excess paste thickness is...
