Abstract：
This paper summaries the current research progresses on the action mechanism of triethanolamine, which is summarized into catalysis, bonding-hygroscopicity-dispersion, emulsification and solubilization. It also classifies the main components and functional properties of two types of compound admixtures derived from triethanolamine early strength agents: TEA-inorganic compound admixture and TEA-inorganic water reducer compound admixture, and provides a brief description of their action mechanisms; by comparing the research status of the two compound admixtures, this paper proposes that the development of compound admixtures should take the following features as the starting point: high efficiency, high performance, high level of environmental protection, high compatibility, and low price, etc. Finally, by comparing TEA with setting accelerator, it is found that TEA has similar functional properties to setting accelerator and that TEA and its derived compound admixtures have potential application prospects in tunnelling.
