Abstract

Abstract:

The compatibility between liquid accelerate and cement is one of the main factors that restrict the application of liquid accelerator. In this paper, the compatibility between liquid accelerator and cement is analyzed in terms of C3A, gypsum and mineral mixture in cement and countermeasures are proposed. The paper can provide theoretical support for the engineering application and technical development of liquid accelerator in the future.

Key words: shotcrete, liquid accelerator, compatibility, C3A, gypsum, mineral mixture
