Global concrete superplasticizer market trend 2023-2028 Why is Polycarboxylate Superplasticizer Modified? by Newsmanysmileys

John Albanese, leader of the Australian Labor Party, was sworn in as Australia's new prime minister. After his victory, Albanese said he would "make a big change" in the country's climate policy.  

"We now have an opportunity to end the 'climate wars' in Australia," he said.  "Australian businesses understand that doing the right thing on climate is good for our economy and good for jobs, and I hope Australia will join the global effort on climate change," Albanese said Australia would engage with other countries to change policies when it came to tackling climate change.  

In addition, Albanese’s Labor Party has proposed a more ambitious plan to cut emissions by 43 percent from 2005 levels by 2030, the report said. However, Labor is not currently planning to phase out coal use or halt new coal mining projects.  

The climate issue was a major concern of voters in Australia's general election. Mr. Morrison, the former prime minister, was criticized for failing to direct the response to repeated bushfires in 2019 and 2020.

SBS has reported that According to the latest Climate Change Performance Index of 64 countries released at the 2021 United Nations Climate Change Conference (COP26), Australia's climate policy ranks at the bottom of all countries, and is one of the world's worst performers in three aspects of emissions, renewable energy, and energy use.  Australia ranks 52nd in renewable energy, 54th in energy use, and 56th in emissions.  

It is predicted that the prices of many other commodities like the concrete superplasticizer would increase in the next few days.

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.

As the Russia-Ukraine conflict continues to develop, there is growing concern about the potential disruption of Russia's energy supply. Geopolitical premiums have pushed up the price of crude oil and natural gas, and the energy price is expected to remain high in the short term. Affected by this, the market price of the concrete superplasticizer may keep rising.
