• Comparative analysis of the effects of three alcohol amine cement grinding aids

  Conclusion: (1) Triethanolamine, triisopropanolamine and diethanol monoisopropanolamine are all good cement grinding aids, which have good grinding effect. (2) Triethanolamine has excellent early strength improvement, but can not even weaken the late strength of cement; triisopropanolamine can not promote the early strength of cement, but can improve the characteristics of late strength; diethanol monoisopropanolamine It has the advantages of both, and has obvious improvement on early strength and late strength. (3) Due to the prevalence of chloride salt early strength agents and triisopropanolamine compared with triethanolamine, there are many advantages in terms of dispersibility, age enhancement, application conditions and relative costs, so the application is gradually increasing. , an increasingly widespread replacement of triethanolamine.

• Factors Affecting Slump Loss of Concrete-Cement

  Factors Affecting Slump Loss of Concrete-Cement The mineral composition and mineral morphology of cement clinker directly affect the hydration and hardening process of cement and the adsorption of additives, so it has a great influence on the construction performance of concrete. Gypsum in cement components also has a great impact on the slump of concrete. In order to improve the label of cement, cement manufacturers will add appropriate grinding aids to improve the specific surface area of cement which will increase the void ratio of the accumulated weight of cement particles, increase the water demand, and accelerate the hydration reaction of cement, increase the slump loss and poor construction performance.

• Sea Sand Can Be Used In Construction?

  With the exhaustion and limited exploitation of river sand resources, the contradiction between supply and demand of construction sand is becoming more and more fierce. The application of sea sand is a systematic engineering, which involves many links such as concrete raw materials, mix ratio, supervision of construction process, late maintenance and so on. In order to avoid the improper application of sea sand in engineering, it is necessary to strengthen supervision on all aspects of the use of sea sand. At the same time, more effective chlorine removal methods and application safeguards should be developed in order to make more effective use of sea sand resources.

• The advantages for Diethanolisopropanolamine than Triisopropanolamine , triethanolamine

  Diethanolisopropanolamine (DEIPA85%) has similar or comparable basic characteristics-dispersibility compared with triisopropanolamine and triethanolamine in cement and cement concrete additives, but its comprehensive performance has obvious advantages. According to the statistical results, under the same conditions, the early strength is higher or lower than that of triethanolamine, and the late strength is much higher than that of triethanolamine. The early strength is much higher than that of triisopropanolamine, and the later strength is lower than that of triisopropanolamine. Its specific characteristics are as follows:

• Chemical concrete admixtures

  The chemical admixture is a component of concrete other than Portland cement, water and aggregate added to the mixture before or during mixing. Producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing, transport, placement and solidification; and to overcome certain emergencies in specific operations. Successful use of admixtures depends on the use of appropriate ingredients and concrete casting methods. Most admixtures are supplied in ready-to-use liquid form and added to the concrete in the factory or on the job site. Certain mixtures, such as pigments, bulking agents, and pumping aids, are used only in very small amounts and are typically batched by hand from pre-measured containers. The effectiveness of the mixture depends on several factors, including: type and amount of cement, water content, mixing time, slump, and temperature of concrete and air.

• The essential properties of cement grinding aid product quality

  Cement grinding aids are good products that are conducive to energy saving in grinding and help to improve the particle properties of the material being ground. For a long time, cement grinding aids have been promoted and applied in cement production, and have achieved good energy-saving and emission-reducing effects. However, in the marketing and promotion of grinding aid products, I believe that there are some “misleading” tendencies that have helped Under the pursuit of different interests, the grinding agent production and operation parties and the cement enterprise users have some deviations in the understanding of the essential properties of the grinding aid product quality. For example, the focus of the use of grinding aids is one-sidedly placed on the functional aspects of “reducing the amount of clinker used, increasing the amount of mixed materials” and “increasing the early strength of cement for three days”.

• Polyethylene glycol PEG 

  While retaining the intrinsic biological activity of natural proteins, PEG ylated proteins can effectively overcome some of the shortcomings of protein drugs in clinical applications, such as increasing plasma half-life, enhancing bioavailability, reducing protein immunogenicity, and improving drug efficacy. And safety, etc. In order to couple PEG to proteins under milder reaction conditions, PEG is activated, and the activated PEG is coupled to an amino group, a thiol group or a carboxyl group on the protein molecule. Many organic small molecule drugs have gradually adopted PEG modification technology, and some progress has been made. The modification of small molecule drugs by polyethylene glycol can transfer many of its excellent properties to the conjugate, so that the polymer Has excellent biocompatibility.

• Comparison of properties of alcohol amine cement grinding aids

  The cement industry is a high-energy-consuming industry, and the energy consumption in the cement grinding process accounts for a large proportion in the whole production process, of which electricity consumption accounts for 60%-70%, and its energy utilization rate is extremely low. About 97% of the energy consumed in the grinding process becomes a waste of heat, and only a small part of the energy increases the surface area of the material, in order to reduce energy consumption, save energy, and improve grinding efficiency.
