Global foam concrete market trend 2022-2029 The solution to the collapse of foam concrete by Newsbabeinthecity

According to statistics from China Chemical and Physical Power Supply Industry Association, China's export volume and export value of lithium-ion batteries have continued to increase. In 2021, China's exports of lithium-ion batteries were 3.428 billion, with a year-on-year growth of 54.34%. The export of lithium-ion batteries was 28.428 billion DOLLARS, up 78.34% year on year. 

From the battery export destination, so far. China's lithium-ion batteries are mainly exported to the Asia Pacific and the United States and other places. In terms of price, the price of foam concrete, led by lithium-ion batteries, is expected to expand globally. 


The common problems of foamed concrete are bubbling, cracking, collapse, shrinkage, and other phenomena. To treat these phenomena, the proper medicine can be found, and the cause can be effectively solved.

The main reason for the collapse of foamed cement is that the cement solidification speed is too slow. We can solve this situation from the following aspects

1. Add accelerator to improve the setting time of foamed cement

Accelerators are used in more and more concrete applications. Foamed cement has high requirements for accelerators. It is not just a fast setting but also needs to be adapted to the performance of foamed cement, and accelerators cannot be added. After affecting the foaming situation.

2 Add an early strength agent to improve the early strength of foamed cement and reduce the stress generated during the exothermic process of cement hydration. Only when these two forces are balanced can it be ensured that the foamed cement will not crack and collapse in the later stage.

3. An appropriate amount of sulfoaluminate cement can be added, which many manufacturers choose to use in winter, and the cost performance is still relatively high. However, this amount of addition should also be paid attention to. It should not be added blindly. After many customers add sulfoaluminate cement, the finished product becomes very brittle in the later stage, without toughness, low strength, and severe pulverization. So we still have to adjust according to the current situation.

4 The water-cement ratio is not suitable. Collapse, retraction, bleeding, insufficient strength. To a large extent, it has something to do with the inappropriate water-cement balance. The adjustment of the water-cement ratio is a technical activity that requires trial and error. It has a lot to do with the cement of foamed cement and the fly ash aggregate, and it needs to be practiced repeatedly according to the actual situation. In this, we can add a plasticizer to adjust the water-cement ratio. This effect is very immediate.


The above contents are some solutions summed up by Tongrun according to the reasons for the collapse of foamed cement. If you encounter other problems or reasonable solutions in the actual process, you are also welcome to communicate us.


The World Food Program (WFP) of the United Nations (UN) and the European Union (EU) said in a statement that the conflict between Russia and Ukraine poses risks to global food supplies, and called on the international community to increase support for vulnerable countries and jointly address food security challenges. 

A few days ago, the Executive director of the World Food Program, the European Commission's commissioner in charge of crisis management, the French Foreign Minister of the ROTATING EU presidency, and other officials held a meeting in Rome, Italy, to discuss how to deal with the negative impact of the Conflict between Russia and Ukraine on global food security. 

One of the officials told a news conference after the meeting that the world was facing a food supply challenge that would "last for many years" as the conflict between Russia and Ukraine pushed up global food prices and disrupted the foam concrete will continue.
