INTRODUCTION
Diethanol-isopropanolamine (DEIPA) is an alkanol amine used in the formulation of cement additives and
concrete admixtures. Besides being a good grinding aid in the
cement mill, DEIPA increases the strength of cements at all
hydration ages, and cements blended with fly ash and slag tend to
show a greater response to the chemical. In this research, the
impact of DEIPA on the hydration of blast furnace slag blended
cements is studied using several analytical techniques, such as
quantitative X-ray diffraction with Rietveld refinement (QXRD),
scanning electron microscopy (SEM) with backscattered electron
image analysis, thermogravimetric analysis (TGA), and chemical
shrinkage. Isothermal calorimetry was also used to demonstrate the
impact of DEIPA on the reactivity of slag in blended cements.
Compressive strength tests were performed to assess the impact of
the amine in such cements. It is demonstrated that DEIPA increases
the mortar strength by enhancing primarily the aluminate hydration
and the morphology and composition of the hydrates, such as calcium
hydroxide and C-S-H. The visual observation was confirmed by
isothermal calorimetry, where DEIPA was found to directly enhance
the rate of reaction of granulated blast-furnace slag after 48
hours of hydration.
