Mechanism of triethanolamine on Portland cement

2015-9-15  1. Introduction. Triethanolamine (TEA) is a weak base surfactant. It can be used as grinding aid for cement manufacturing (typically at dosage of 0.1%, weight percentage of clinker), in order to prevent agglomeration of powder and coating formation on milling ball surface .TEA can also be used as component of chemical admixture, such as shotcrete accelerator or water reducing admixture, in ...
