The latest forecast from consulting firm AlixPartners is that the chip shortage may cost the global auto industry $110 billion; it will reduce global auto foam concrete.
What are the types of foam concrete foaming agents?
The foamed concrete foaming agent can make concrete appear a lot of foam to accelerate the formation and use of foamed concrete. Use efficiency and speed up the progress of the entire construction project. Foamed concrete foaming agents are available in the market. What are the types of foam concrete foaming agents?
What is foam concrete foaming agent?
The foamed concrete foaming agent is a substance that can make its aqueous solution generate a large amount of foam when the mechanical force is introduced into the air. This kind of substance is a surfactant or a surface-active substance. The former such as anionic surfactants, cationic surfactants, non-ionic surfactants, etc., and the latter, such as animal protein, vegetable protein, pulp waste liquid, and so on. Foamed concrete foaming agent, also known as a cement foaming agent, foam concrete foaming agent refers to an admixture that can reduce the surface tension of the liquid and generate a large amount of uniform and stable foam for the production foamed concrete.
2. What are the types of foam concrete foaming agents?
This type of foaming agent is made of rosin as the main raw material, and its application has long been common. The chemical structure of rosin is relatively complex, containing rosin acids, aromatic hydrocarbons, aromatic alcohols, aromatic aldehydes, and oxides. Rosin resin foaming agent is also known as an air-entraining agent. Its main varieties are rosin soap and rosin homopolymer. It was initially developed and applied as an air-entraining agent for concrete mortar and later expanded to be used as a foaming agent for foamed concrete.
(2) Synthetic class
Following the rosin-based foaming agents, various synthetic surfactant-based foaming agents have been developed. This type of foaming agent has been widely used in cement foaming abroad since the 1950s. Among various synthetic surfactant foaming agents, the anionic type is generally welcomed due to its fast foaming and large foaming multiple. The cationic foaming agent is expensive and has a certain influence on the strength of cement, so it is not used much.
(3) Protein active substance type
The protein-based foaming agent is the current high-grade foaming agent with good performance and good development prospects. From the general development trend, it will occupy a larger and larger proportion in the application in recent years. Although its price is high, mostly above 15,000 yuan/ton, it will still be accepted by the market due to its better performance.
There are many foam concrete foaming agents, but there are only three or four common ones. The use of foamed concrete foaming agents can accelerate the formation of concrete and quickly make the concrete reach the standard of use, thereby promoting the progress of the entire construction project. , The development of foam concrete foaming agents has gone through a long process, and it is currently widely used in construction projects.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".
The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.
The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.
The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.
Affected by several factors, the supply of the foam concrete is erratic and thus its prices are expected to go higher in the future.
