Diethanol-isopropanolamine (DEIPA) is a new type of alkanolamine used as grinding aids for Portland cement.
In this study, the effect of DEIPA on properties of Portland limestone cement (PLC) were investigated by measuring strength of mortar, setting time, compatibility of cement and superplasticizers.
A combination of isothermal calorimetry, scanning electron microscopy and mercury intrusion porosimetry was used to investigate the hydration kinetics.
The results indicate that the addition of DEIPA markedly enhances the early and late strength of mortar, which gains a 4.4 MPa increment (28.7 %) at 3 d and a 6.3 MPa increment (20.3 %) at 28 d, respectively, and is not significant differences in the setting time.
However, the compatibility of cement and superplasticizer becomes poor in the cement paste containing DEIPA.
The working mechanism of DEIPA accelerates the hydration of aluminate and alite, and promotes the formation of AFt and monocarboaluminate, as well as the transformation of AFt to AFm.
Besides, the addition of DEIPA results in uniformly overlaps hydration products and improves microstructure in hardened cement pastes

Diethanol-isopropanolamine (DEIPA) is a new alkanolamine in cement grinding agents.
Figure 1 shows a schematic representation of the chemical structure of DEIPA.
There have been a few studies on the influence of DEIPA on the hydration of Portland cement.
L. Jardine [17] investigated that DEIPA was preferred for improving early strength when admixed into cementitious compositions.
Riding [18] observed that DEIPA increased the early age mortar strength and affected the morphology of calcium hydroxide
(CH). Ma [19, 20] also observed that DEIPA can increase the early and late strength and promote the formation of AFt and microcrystalline CH at early stages.
J. Cheung [21] reported DEIPA can enhance the compressive strength of the limestone blended cement.
Nevertheless, the effect of DEIPA on the properties and hydration process of PLC is unknown.
In this work, DEIPA was added into PLC to investigate the effect on properties (compressive strength, setting time and compatibility of cement and superplasticizer) and hydration kinetics.
In addition, the mechanism of cement hydration in the presence of DEIPA was discussed

Diethanol Isopropanolamine (DEIPA) is often used in cement grinding aids to replace Triethanolamine and Triisopropanolamine in grinding aid raw materials.
Diethanol Isopropanolamine is a new green grinding aids raw materials.

Description
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

DEIPA improves both initial strength and later strength of cement.
DEIPA also heps to get better effect of later strength than TIPA does.

Diethanol-isopropanolamine (DEIPA) is a tertiary alkanolamine used in the formulation of cement grinding-aid additives and concrete early-strength agents.

Diethanolisopropanolamine (DEIPA)
Diethanolisopropanolamine (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.

A grinding aid (DEIPA) is a specialty chemical agent used to make it easier to grind and mix cement.
Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process.
Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity.
These benefits of cement grinding aid use also contribute to lower energy costs on the part of industrial mills.

The grinding aid began to gain popularity in the mid-20th century as a reliable tool for cement processing.
Its effectiveness and reputation for reliability lie in its ability to reduce surface tension between cement particles brought on by the stress of the grinding process.
Chemical compounds known for their polar properties, such as alkanolomines, disperse charges on the surface of the cement particle.
This covering of charges prevents individual particles from clumping together.
Hydration is also an important factor in the grind aid process.
When a grinding aid (DEIPA) comes in contact with a cement particle, it forms an instant gel around the particle.
This gel hydrates the grain and initially serves as a barrier from other cement particles. With time, the gel crystallizes.
This crystallization allows the cement particle to attach itself to others, forming a fluid lattice structure.

DEIPA advantages compared with TIPA:

According to the research, their effects on cement properties is better than the ordinary cement grinding aids as TEA & TIPA, the cement compressive strength in all ages were improved when DEIPA was added to cements.
The effect of DEIPA and TIPA were similar on cement properties including normal consistency, setting time, fineness and fluidity, etc.
DEIPA is excellent cement grinding aid.
