Global concrete foaming agent market trend 2025-2027 Effect of Concrete Additives on Concrete Quality by Newsteampindar

A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including concrete foaming agent.

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.

Chile's government has decided to create a state-owned lithium enterprise and hopes to establish a model for the company by the end of the year, Mining Minister Marcela Hernando said in an interview.  

Chile is the world's second largest lithium producer and has the largest reserves of lithium in the world. The domestic lithium industry is currently dominated by two private companies, Albemarle and SQM.  

Chile wants to participate more closely in the booming lithium market after leftist President Gabriel Boric took office in March. The accelerating electrification of the global auto industry has helped push prices of lithium, a key raw material for electric car batteries, to record highs over the past year, lapping up more players, including Mexico and Argentina, who want a piece of the market.  

According to Hernando, the government is setting up a task force to determine the best way to run state-owned lithium enterprises. She said the government hopes to establish plans by the end of the year for how the company will develop and what business model it will operate under. 

Hernando stressed that while the state would be a major shareholder in the proposed company, it was open to private investment.
