The demand for water reducing agents is increasing year by year, why should we use it?

Due to the complexity and variability of concrete raw materials, the diversification of engineering technical requirements, and the performance characteristics of water-reducing agents that are different from other types of water-reducing agents, in recent years, the demand for water-reducing agents has been increasing year by year. More and more industries have used admixtures as essential materials. Why should they be used? What are the advantages? The engineering community should have a deeper understanding of this new product and consider the technical difficulties that may arise from the use of this product. Take effective measures to avoid adverse phenomena. The editor of Anhui Yulong New Materials Co., Ltd. will take you through it, I hope it will be helpful to you

The application of water-reducing admixtures with twice the result with half the effort provides guarantee for high-performance concrete structure projects, plus It is only one aspect of the problem that agent manufacturers provide water-reducing agent products that meet the requirements of various testing indicators.

Water reducing agent is an important additive in the construction industry. It has a strong ability to maintain the dispersion of cement particles. It is used in infrastructure construction projects such as railways, nuclear power plants, hydropower stations, offshore engineering projects, and water transmission projects in my country. The use of water-reducing admixtures in concrete projects is mandated by formulating concrete technical standards, and projects involving a large number of concrete projects such as highway construction, bridges, and airports are also promoting the use of high-performance water-reducing admixtures. With the technological innovation and cost reduction of water-reducing agent polyether products, it is expected to gradually replace the traditional naphthalene-based water-reducing agent in the future, and is in the early stages of growth.

Should everyone use water-reducing agents? The editor has summarized the following points:

Salt high-performance water-reducing agents can be prepared with special properties and uses by adjusting the molecular structure. Super water reducing agent, such as: low temperature high early strength type, zero slump loss type, anti-shrinkage type, etc.

Using water-reducing agents, more slag or fly ash can be used to replace cement, thereby reducing costs;

The raw materials for the synthesis of polymer backbones come from a wide range of sources, and the monomers are usually There are: acrylic acid, methacrylic acid, maleic acid, ethyl (meth)acrylate, hydroxyethyl (meth)acrylate, sodium allyl sulfonate, methyl methacrylate, etc.;

The water-reducing agent has good slump retention, and there is basically no or little slump loss within 90 minutes;

Under the same fluidity, it has little impact on the cement setting time and can effectively solve the problem of water reduction. , air entrainment, retardation, bleeding and other problems;

The water-reducing agent has a large degree of freedom in its molecular structure, many controllable parameters in admixture manufacturing technology, and has great potential for high performance;

Diversified polymerization pathways, such as copolymerization, grafting, block, etc. The synthesis process is relatively simple, and since no harmful substances such as formaldehyde and naphthalene are used, it will not cause pollution to the environment.

At present, the usage of Japanese water-reducing admixtures in concrete has accounted for more than 90%. In our country, the output of naphthalene-based water-reducing agents is still less than that of naphthalene-based water-reducing agents. However, the water-reducing rate of naphthalene-based water-reducing agents is low, and the disadvantages of large slump loss of the prepared concrete are becoming more and more apparent in use.

The compounding of water-reducing admixtures needs to be fully tested based on the actual needs of the project and the actual conditions of the compounding components used, so as to obtain a better compounding plan and compounding ratio. With the development of research on the structure-activity relationship of superplasticizers, it is now possible to produce a variety of functional superplasticizers on a large scale, including slump-preserving type, early strength type and viscosity reducing type. Although the functional diversity of water-reducing admixtures can be achieved through synthesis, the compounding of water-reducing admixtures with other admixtures is still a more economical and effective way to improve their own performance.

That’s it for the knowledge about water reducing agents. Your needs are our goal and pursuit. Thank you sincerely for reading and I hope you will gain something. </p
