Triisopropanolamine (TIPA) is a surface active material that can greatly reduce the surface tension of water. When the cement is stirred with an aqueous solution doped with a trace amount of triisopropanolamine (TIPA), the surface tension of the solution is changed. The effect of the solution on the emulsification, wetting, permeation, adsorption and dispersion of the cement particles is remarkably enhanced, and it is easier to expand and adsorb on the surface and inside of the cement particles, so that the deep layer of the cement continues to be hydrated. Triisopropanolamine (TIPA) has a strong polarity due to its spatial three-dimensional molecular structure. It can play a good role in dispersing particles during cement grinding, so that cement particles do not agglomerate and form a larger ratio. Surface area, thus achieving a grinding effect.
In the past 40 years, the application of water reducing agent in concrete has been rapidly developed. Polycarboxylate water reducing agent has become an indispensable component for the preparation of high performance concrete as a new generation of water reducing agent. However, the problem of poor adaptability of polycarboxylate water reducer (PCE) to cement has been a technical problem for cement manufacturers, concrete construction units and admixture manufacturers. Grinding is the most energy-consuming part of the cement production process. Improving the mechanical structure of the grinding and adding grinding aids during the grinding process are effective measures to reduce energy consumption and improve grinding efficiency. With the implementation of the energy conservation and emission reduction strategy, the proportion of grinding aids used in China's cement grinding process has exceeded 50%.
Triethanolamine (TEA) and its solution are used as engineering admixtures and early strength agents in the cement clinker grinding process, which can not only prevent the aggregation and air cushion of the pulverization process, improve the fluidity and packing density of the cement, but also Reduce the power consumption of the pulverizer, increase production efficiency, increase production capacity, and increase the fineness of cement and improve the quality of cement products.
Diethanolisopropanolamine (DEIPA) is a low toxicity, environmentally friendly alcohol amine fine chemical product, mainly used as a surfactant. More applications in cement additives. There are no three wastes in the production process, and green environmental protection is well known. The cement industry is a high-energy-consuming industry. In the cement grinding process, 95% of the energy disappears as heat. When the fineness of the cement increases, the efficiency of cement selection decreases due to the aggregation of fine particles, resulting in a sharp drop in grinding efficiency. One way to improve this situation is to add a cement grinding aid to the mill during the grinding process to add certain grinding aids, such as diethanol monoisopropanolamine and triisopropanolamine, etc. Improve cement production. The application of cement grinding aid has great practical significance for energy saving and emission reduction in China.
In the cement industry production, in order to improve the grinding efficiency, reduce the power consumption of the mill, reduce the fineness of the cement, and improve the quality of the cement, a small amount of material-grinding aid must be added during the grinding process. The grinding aid is composed of one or more surface active substances and other chemical additives. It can reduce the surface energy of the grinding powder during the grinding process, overcome the attraction between the grinding powder, reduce the crushing resistance and prevent Paste the ball. Improve the fluidity of the mill, thereby reducing the power consumption of the mill and improving the grinding efficiency.
In general, high-performance concrete refers to concrete with high durability, high strength and high fluidity. The biggest difference between raw materials and ordinary concrete is that the high-performance water reducing agent and ultra-fine mineral admixture are the fifth concrete. The sixth essential component, their performance is the focus of the current concrete engineering and materials circles in various countries. High-performance water reducing agent, which belongs to organic chemical materials, including material type and property characteristics, raw material selection and synthesis process control, product molecular morphology structure and performance, to the physicochemical mechanism of water reducing agent in cement dispersion system, minus The influence of water agent on cement hydration performance and its application technology in concrete have yet to be systematically studied in theory and practical application.
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.
It can better guide the construction of the project. The construction period of highway bridges is generally high, the quality control requirements are relatively high, and the total investment of the project is very large. In order to avoid quality problems and ensure that the project meets the requirements for use, the construction unit needs to strictly control the quality of the raw materials during the construction phase, so it is necessary to use the admixture reasonably.
