What is Water Reducer?

Now China has become a powerful country in science and technology, but do you know how powerful China's technology is? The manned space station alone is not enough, and now it has successfully broken through the key technology of nuclear fusion, even leading the world by 15 years. Does this mean that China is not far from the artificial sun? It turned out that the fully superconducting tokamak nuclear fusion experimental device developed by China at the Hefei Research Institute of the Chinese Academy of Sciences successfully achieved a record of 101 seconds of continuous operation at 120 million degrees Celsius, and broke the world record. Compared with the previous record in South Korea, China has time has been directly extended by 5 times, and it seems that we are one step closer to the practical stage of artificial sun.
The success of nuclear fusion technology will lead to the development of Water reducer.

Introduction to Water Reducer:

Water reducer, or water reducing agent, concrete water reducer, cement water reducer, is a special chemical product added to the concrete mixture before pouring, belonging to a kind of concrete admixture. A concrete admixture is a chemical that is added during the concrete-making process to improve concrete performance. Admixtures in concrete are small (no more than 5%) but indispensable. The compound water reducing agent is mainly used in ready-mixed concrete, which is used in infrastructure construction and real estate construction.

According to the water reduction rate, the water reducer is divided into ordinary water reducer (the first generation), efficient water reducer (the second generation), and polycarboxylic acid (also known as superplasticizer) high-performance water reducer (the third generation).

The first generation of water reducer is lignosulfonates, which have been used since the 1930s and are cheap products derived from the wood and paper industries. 

Due to the excellent slump performance and environmental protection and pollution-free processing process, the polycarboxylic acid series water-reducing agent quickly replace the naphthalene series water-reducing agent has become the mainstream water-reducing agent at present, the production of polycarboxylic acid series water-reducing agent has accounted for nearly 80%. 

Production Process of Water Reducer:

High-performance water reducing agents and efficient water reducing agents are compounded by their mother liquor, the raw materials of their mother liquor are polyether monomer and industrial naphthalene, polyether monomer also need to be further synthesized by ethylene oxide.  Industrial naphthalene is produced from coal chemicals, and there are currently three ways to produce ethylene oxide, including petrochemical, coal-chemical, and alcohol processes. 

There are some technical barriers to chemical synthesis and physical compounding of the two main production processes of water-reducing agents.

Chemical synthesis involves polymerization technology in the field of polymer chemistry. In the research and development and production of products, relatively professional personnel are required, and long-term technical experience and industrial scale-up production experience are required.

Advantages of Water Reducer:

Under the condition of constant cement content, the water reducer can reduce water consumption and improve concrete strength. Under the condition of constant workability and strength, the admixture of cement dosage can be saved. 

1. Reduce water content by 5-10%;

2. Reduce the porosity of concrete;

3. Increase concrete strength by up to 25% (because the concrete mixture requires less water to remain processable);

4. Increased workability (assuming free water remains constant);

5. Reduced water permeability (due to less water used);

6. Reduce the diffusion of the corrosive agent in concrete, so as to improve the durability of concrete;

7. Provide a better finish to the surface.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the Water reducer, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the Water reducer chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.

The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these "payoffs" in the early pandemic environment. For more information about Water reducer, please feel free to contact us.
