[Triethanolamine supply] Triethanolamine can be used as cement early strength agent

Image keywords

Triethanolamine is a colorless, transparent and viscous liquid at room temperature, with a slight ammonia smell. It is hygroscopic and can absorb moisture and carbon dioxide in the air. Can be freely mixed with water and alcohol, soluble in chloroform, slightly soluble in benzene and ether. The pH of 0.1moI/L solution is 10.5. There is a danger of burning when exposed to high heat, open flame or contact with oxidants. Its aqueous solution is corrosive.

Triethanolamine can be used as an early strength agent for cement:

Triethanolamine is a commonly used early strength agent in my country’s cement industry. The role of early strength agent It accelerates the hydration process of cement and improves early strength under the condition of the presence of liquid phase in concrete.

Although triethanolamine does not change the hydration products of cement, it can enhance the activity of the colloids generated by cement hydration, generate pressure on the surroundings, block capillary channels, and intensify adsorption, wetting, and particle dispersion. It promotes the reaction between C3A and gypsum to form calcium sulfoaluminate hydrate, which can improve the compactness, impermeability and frost resistance of concrete, and play the role of early strengthening and improving strength.

When used in combination with inorganic salt materials, it can play a catalytic role in the hydration of the cement itself and the reaction between the inorganic salt and the cement, making the early strength effect particularly significant.
