  • Comparison of triethanolamine, triisopropanolamine and diethanol monoisopropanolamine

    Cement is a very basic material in the construction industry and plays a very important role in the development of the national economy. However, in the cement production process, the energy consumption is high and the utilization rate is low, mainly due to the accumulation of fine powder particles during the grinding process, which causes the paste ball and the adhesive liner to reduce the grinding efficiency, so that about 80% to 90 % of the energy is consumed in the form of heat. In order to improve this situation, it is common in the industry to add a small amount of grinding aid to the grinding material to improve the grinding effect.
    Rate and reduce the energy consumption of grinding.

  • Triethanolamine is an important fine chemical product

    Triethanolamine is an important fine chemical product and a commonly used raw material for cement grinding aids and concrete admixture manufacturers.

    Triethanolamine (TEA) can form a water-soluble chelate with cations in cement hydration system, and forms many melting points on the surface of cement particles, which increases the dissolution rate of C3A and C4AF, resulting in faster reaction with gypsum. The increased amount of calcium sulphoaluminate is beneficial for coagulation and compaction, thereby increasing early strength. At the same time, due to the formation of unstable complexes in the hydration process of cement, the degree of supersaturation of Ca(OH)2 is increased, which can effectively prevent the formation of loose crystalline products in the early stage of C3A hydration, thereby improving the compactness of cement stone and strength.

  • concrete admixtures

    Concrete additive is an admixture added during concrete mixing. It is mainly used to improve the performance of concrete. From the point of addition ratio of admixture, generally not more than 5%.
    For all kinds of concrete admixtures, the role of the precipitant is mainly to reduce the water consumption, increase the density and elasticity of the concrete, and make the concrete durable. The air entraining agent can improve the solubility of the concrete, and reduce the internal crack of the concrete by improving the internal structure of the concrete, so that the concrete can improve its antifreeze and impermeability. For concrete with high frost resistance requirements, it is possible to properly perform bleed air or a mixture of precipitation additives.

  • Selection of Concrete Admixtures

    Concrete admixtures shall be selected carefully as per the specifications and shall be used as recommended by the manufacturer or by lab testing report. The quantity of admixtures to be used for specific application of admixtures are recommended by the manufacturers.
    For use in large construction projects, the quantity of the admixture to be used shall be obtained from tests reports for concrete mixed with admixtures at various percentage admixtures use. These tests are conducted to understand the behaviour of admixtures on the desired quality and strength of concrete at different quantity of admixtures used. Thus, the optimum quantity of admixtures can be selected for specific application based on results.
