Stiffening control of printable cement paste with flash setting admixture
Abstract
Printable cement paste should be easy to convey in pipelines and well set in a short period of time after extrusion. Mixing flash setting admixture into cement paste at the printer mozzle is a potential way to achieve this goal. The mixed in flash setting admixture can speed up the hydration process, leading to a faster stiffening of the printed cement paste. In this study, several batches of cement paste with flash setting admixture dosages of 0 %, 2 % and 4 % of the cement weight were prepared. Then, based on a predefined cement paste, the influence of different dosages of flash setting admixture on the rheological properties (e.g. storage modulus, yield stress) was explored. The evolution of yield stress and storage modulus in function of time is given to evaluate the structure development of all cement pastes. The results give some preliminary insight in the effect of flash setting admixture on the accelerated stiffening of the printable cement paste.
