Applications:
Cement Grinding Aids: DEIPA 85% is used as cement grinding aid to enhance grinding efficiency, reduce clinker particle agglomeration, and improve cement flowability, resulting in higher throughput and lower energy costs.
Concrete Admixtures: Improves the workability and strength of concrete, making it ideal for high-performance concrete used in construction projects such as bridges, buildings, and infrastructure.
Chemical Intermediates: Serves as a versatile intermediate in the synthesis of surfactants, emulsifiers, and corrosion inhibitors for applications in coatings, lubricants, and agricultural chemicals.
Industrial Formulations: Acts as a neutralizing agent and stabilizer in specialty chemicals, enhancing product performance in industries such as textiles and metalworking fluids.
Technical Mechanism
DEIPA acts as a surface-active agent, reducing electrostatic attraction between cement particles during grinding. This leads to:
- Better dispersion
- Reduced coating effect
- Increased mill output
Additionally, DEIPA promotes hydration reactions, improving C3A and C4AF phase activity, which directly enhances cement strength.

FAQ:
What is Diethanol Isopropanolamine (DEIPA)?
Why choose DEIPA 85% over TEA or TIPA?
What are the typical dosage & adding method?
Dosage: 0.03–0.08% by cement weight (pure DEIPA); 0.01–0.05% for single use, 0.005–0.03% when blended.
Adding point: Feed belt, mill inlet, or pre-grinding bin; metered & uniform addition required.
Does DEIPA 85% affect the setting time of concrete?
How does DEIPA 85% improve cement grinding efficiency?
What cement types is DEIPA suitable for?
Ordinary Portland cement (OPC), blended cement (slag/fly ash/limestone), high-C₄AF cement, fine slag powder.
How does DEIPA work in cement grinding?
Grinding efficiency: Adsorbs on cement particles, reduces electrostatic agglomeration & coating on grinding media; improves particle dispersion, reduces over-grinding.
Strength boost: Accelerates clinker hydration; activates slag/fly ash/limestone; increases 3d (3–5 MPa) & 28d (4–8 MPa) strength.
Flowability: Lowers angle of repose, improves silo discharge & workability.
