Abstract

In many applications such as grouting, shotcrete, and 3D concrete printing, conflicting material requirements exist between the transportation and fabrication process, as fresh materials should be pumped easily with a low stiffening rate and a high fluidity while a rapid strength gain must occur after placement. In such applications, it is therefore imperative to achieve a stiffening control of the concrete. In this paper, we discuss how the inline mixing process of an accelerator post-pumping can be used to achieve this stiffening control. We begin with a review of the mechanisms of various commonly used accelerators. This is followed by a detailed discussion on the inline mixing process of accelerators. Finally, we also point out the problems and challenges of using accelerators in these applications.
