Global concrete foaming agent market trend 2023-2028 Effect of Concrete Additives on Concrete Quality by Newskxcad

As the European Union tries to reduce its dependence on Russian energy, the Russian president recently said Russia would try to shift its energy exports to the east, adding that there was no way for European countries to give up Russian gas immediately.

Russia supplies about 40 percent of the EU's gas, and western sanctions imposed over the conflict with Ukraine have complicated financing and logistical arrangements for existing agreements, hitting Russian energy exports, the report noted.  

Russia has been building closer ties with China and other Asian countries as the European Union debates whether to impose sanctions on Russian gas and oil and member states seek supplies from elsewhere, Reuters said.  

"So-called partners from unfriendly countries admit that they cannot survive without Russian energy, including gas," the Russian president said in a televised government meeting. There is no reasonable alternative to Russian gas in Europe right now."  

He also said Europe was driving up energy prices and destabilizing markets by talking about cutting off Russia's energy supplies. Russia, which produces about a tenth of the world's oil and a fifth of its natural gas, will need new infrastructure to increase energy supplies to Asia, he said.

He ordered Moscow to submit a plan by June 1, including "the expansion of transport infrastructure to countries in Africa, Latin America, and the Asia-Pacific region".  

He also sought to clarify the possibility of integrating two pipelines -- the Sakhalin-Khabarovsk-Vladivostok gas pipeline in the Far East and the "Power of Siberia" gas pipeline to China -- into Russia's unified gas supply system. In theory, connecting these routes to larger gas networks could allow Russia to divert gas from Europe to Asia.

Because of the ever-changing international situation, the supply and prices of international bulk concrete foaming agent are still very uncertain.

Concrete is the main raw material of modern construction engineering, and it is welcomed because of its high strength and long service life. In the process of concrete mixing, adding appropriate amount of admixture can improve the performance and quality of concrete.

 

Concrete Additives

In general, the substances added to concrete to improve the performance of concrete in the mixing process and before mixing are called admixtures. In general, the quality of the admixture mixed into concrete shall not be greater than 5% of the cement quality.

 

Retarder, accelerator and early strength agent can adjust the hardening property and setting time of concrete.

The main function of admixtures such as air entraining agent, water reducer and pumping agent is to improve the rheological properties of concrete mixture and make it easier to be pumped to the designated location.

Admixtures such as waterproofing agent, air entraining agent and rust inhibitor are used to improve the durability of concrete.

In order to improve the other properties of concrete, admixtures such as colorant, aerating agent, antifreeze and expansive agent need to be mixed into concrete.

 

Influence of Superplasticizer

It would affect the collapse degree of concrete.

In general, a certain amount of superplasticizer is added to concrete to achieve the purpose of increasing the collapse of concrete, which can effectively improve the workability of newly mixed concrete.

 

Experience shows that the collapse of concrete without superplasticizer within 1 hour is less than that of concrete without superplasticizer. The main reason for this phenomenon is that concrete still needs to go through the processes of mixing, transportation and pouring after adding superplasticizer. Therefore, it is necessary to use the method of adding water to restore the collapse of concrete mixed with superplasticizer in the concrete construction site, but this method will significantly reduce the performance such as coagulation strength, which may lead to concrete cracking, abnormal hardening and other phenomena.

 

In order to effectively solve the problem of collapse loss of concrete mixed with superplasticizer, it is suggested that the method of adding superplasticizer in batches and post-admixture should be adopted. The batch mixing method can not only effectively avoid the loss of concrete collapse, but also control the production cost to a certain extent and realize the benefit of concrete construction.

 

Function of Antifreeze and Early Strength Agent

Antifreeze is a kind of admixture which can prevent the moisture in the material from freezing at low temperature. for example, when the project is below zero in winter, it can make the concrete work normally at low temperature.

 

Early strength agent refers to the admixture which can improve the early strength of concrete and has no significant effect on the later strength.

 

When the anti-freezing agent is constructed in winter, when the concrete strength reaches a certain limit value, because the structure has been initially formed and has the ability to resist frost heave damage, the concrete will not be frozen even if it is frozen again, which is called the anti-freezing critical strength of concrete.

 

Concrete early strength agent refers to the admixture which can improve the early strength of concrete and has no significant effect on the later strength. The main function of early strength agent is to accelerate the hydration rate of cement and improve the early strength of concrete.

 

Antifreeze is that when the temperature of the concrete project is zero or below zero in winter, it can make the concrete work normally at low temperature.

 

The early strength agent does not contain chloride ion and has no rust effect on steel bar, so it is suitable for all civil, industrial buildings and prestressed reinforced concrete members, mortar and so on. It is most suitable for construction at low temperature in early winter and early spring. When used in Portland cement, it plays a particularly significant role in strengthening and modifying slag cement.

The secretary of Ukraine's National Security and Defense Council said the US arms lease bill to Ukraine has not yet been implemented. This is still in the process and could start from July to September 2022, he said. The approval of this bill is a very positive decision for Ukraine. Aid to Ukraine through lend-lease will eventually come, the question is when.  

In an effort to speed up the supply of weapons to Ukraine, President Joe Biden signed a defense lend-lease bill for Ukraine at the White House on May 9.


Nippon Steel, JFE Steel, and Kobe Steel will work together to develop a steel-making process that uses hydrogen to reduce carbon dioxide emissions without using blast furnaces. Small test furnaces will be built at Nippon Steel's Hwazaki Research and Development Center (Kamiki city, Ibaraki Prefecture) and JFE's East Japan Steel In Chiba (Chiba City). The two test furnaces, which will be operational by 2024-25, will confirm whether ore with high levels of impurities can also operate smoothly.
