Global concrete superplasticizer market trend 2025-2030 Why is Polycarboxylate Superplasticizer Modified? by Newswrigleyfieldnews

Russian President says if the European Union imposes an oil embargo, Europe will buy energy at the most expensive price and economic activity in Europe will weaken. Rosneft needs to change its business model. Russia will help facilitate settlement and access to loans and insurance in its own currency.

According to Reuters, the European Commission will unveil a 210 billion euro plan on how Europe can end its dependence on Russian fossil fuels by 2027 and use its distance from Moscow to accelerate a shift to green energy. According to a draft document seen by Reuters, Brussels will propose a three-pronged plan to wean countries off Russian fuel: switch to importing more non-Russian gas, move more quickly to promote renewable energy, and work harder to conserve energy. The draft measures, which include EU law, non-binding plans, and possible recommendations by national governments, are subject to change before publication.

Austria is not a member of NATO and will not seek membership in the future, the Austrian Foreign Minister said in Brussels recently. He stressed that it was "their choice" for Sweden and Finland to seek NATO membership, while Austria would remain neutral.

The supply and prices of many other concrete superplasticizer are expected to continue to be influenced by international situations.

Concrete water reducing agent is one of the technical ways to reduce the cement dosage, improve the utilization rate of industrial waste residue, and realize the durability and high performance of concrete. It is also one of the key materials for the development of concrete to high-tech field. And polycarboxylate type water reducing agent (PC) has become a kind of efficient water reducing agent with the most rapid development and the largest market potential because of its low toxicity and environmental protection characteristics.  Compared with the traditional admixtures, the admixtures have become the focus of worldwide research and development because of their excellent dispersibility and slump retention ability. 

Although polycarboxylate water reducing admixture outstanding performance and ability to maintain good slump has been widely recognized, but because of the existence of mineral composition, cement fineness, cement plaster form and content, admixture adding amount, and the mixing process of concrete mixture ratio, water has a very high sensitivity, seriously affected the existing products are widely used in engineering. 

 

 

What is Polycarboxylate Series Water Reducing Agent?

Polycarboxylate superplasticizer is a kind of surfactant containing carboxylic graft copolymer. Its molecules are comb shaped and have high steric hindrance effect. As the third generation of high-performance water reducing agent after lignosulfonate ordinary water reducing agent, naphthalene series aliphatic group, sulfamate and other high-efficiency water reducing agent. 

It is because of molecular structure design performance is good, high reduce water, low admixture amount, keep slump good, enhance good, contain alkali amount is low, to set time influence is small, and most cement compatibility is good and pollution-free and other advantages are regarded as the most development potential of water reducing agent variety.

 

Polycarboxylate superplasticizer is a new high-efficiency superplasticizer developed and produced successfully after naphthalene, melamine, aliphatic and sulfamate superplasticizer.  In its content is low (solid content 0.15% - 0.25%) can produce an ideal water reducing and enhanced effect, less impact on the setting time of concrete and slump retention, adaptability to cement and admixture is relatively good, a smaller influence on drying shrinkage of concrete (usually not too much increase drying shrinkage), without the use of formaldehyde in the process of production and does not discharge waste liquor, SO  The low content of 42- and Cl- has been praised by researchers and some users since the beginning. 

 

Why should Polycarboxylate Superplasticizer be Modified? 

Compared with naphthalene series high efficient water reducing agent, such as, although poly carboxylic acid water reducing agent in the reduction of water conservation slump has obvious advantages in aspects of environmental protection, but there are some technical problems in the practical engineering application, such as water reducing effect of concrete raw materials, mixing ratio, water reducing agent dosage dependence is very big, fresh concrete performance is sensitive to water consumption, easy preparation of large liquidity segregation layer. Poor compatibility with other water-reducing agents and modified components and poor product stability greatly restrict the wide application and development of polycarboxylate water-reducing agents. 

 

In order to overcome the technical defects in the application of polycarboxylate water-reducing agent, or to improve some or some properties of concrete (workability, slump retention, reduction of bleeding, improvement of early strength, low shrinkage, etc.), it is necessary to modify the concrete. 

In practice, the commonly used modification methods include synthetic technology and compound technology. Compared with the synthetic process, the compound method has the advantages of simple operation and low cost, so it is widely used in practical applications. Polycarboxylate series compound technology, is the polycarboxylate series water-reducing agent and other components (such as slow coagulation, defoamy, air induction, early strength and other components) according to a certain proportion of the combination compound, in order to achieve the coordination of the superposition of each component.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.  

On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.  

Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.  

Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March.  It is also the highest since comparable data began in 1999.  

The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the concrete superplasticizer .
