摘要

N,N,N’,N’-Tetrakis-(2-hydroxyethyl)ethylenediamine (C ₁₀ H ₂₄ N ₂ O ₄ ,THEED) is a different type of alkanolamine. In this work, the physical and chemical effects of small amounts of THEED added to Portland cement were investigated. THEED can be used as an accelerator for the setting of Portland cement. The compressive strengths of standard test mortars moist-cured for 1, 3, 28 and 90 days were enhanced in some cases by the addition of THEED. THEED promoted conversion of ettringite (AFt) to monosulfoaluminate (AFm). THEED had notable effects on the morphology of AFt and C-S-H at the early age, especially on the growth direction of portlandite(Ca(OH) ₂ ) crystals.
