6 problems to pay attention to before and after the construction of foamed concrete

Europe's largest economy, Germany, recently activated an emergency plan to manage gas supplies that the natural gas could be rationed if supplies are disrupted or disrupted by a stand-off over Russian demands to pay for fuel in rubles.  

German Vice-Chancellor, minister of economy and climate protection, said Germany's gas supplies were secure for now, but he urged consumers and businesses to reduce consumption, saying "every kilowatt of electricity counts." 

Germany's gas network regulator can ration gas if supplies run short. Plants would be the first to be affected. Special treatment will be provided to private families, hospitals, and other important institutions.  

Half of Germany's 41.5 million households use natural gas for heating, and industry consumption accounts for a third of the country's 100 billion cubic meters of gas demand in 2021.  

The price of many energy and commodities like the foamed concrete could be affected.

1. Determine the material

The compatibility of cement foaming agents and the foaming machine is the first consideration. Because there is a problem with compatibility between cement foaming agent and cement foaming machine. To understand the compatibility of the cement foaming agent, it is also necessary to determine the reasonable dilution ratio of the foaming agent. If it is the first time using the cement foaming agent, it is recommended to refer to the dilution ratio recommended by the manufacturer and then combine it with your machine test to find the most suitable dilution ratio.

2. Cleaning up the construction site

The first is to clean up the debris and install the water and electricity. Sprinkle cleaning to moisten the surface of the cast-in-place operation; pay attention to the watering must be even and do not have water accumulation.

3. Test whether the foam generator is regular in advance

The test method is to dilute the foaming agent according to a specific ratio, then make foam, and arrange the foam outside the machine to see whether the foam moisture content and the viscosity of the foam are standard.

Whether the bubble is about 1mm, if the moisture content is high, the cells may need to be replaced with steel balls.

4. During the construction of foamed concrete, it should be noted that the slurry of foamed concrete cannot stay, and it should be leveled immediately after pouring to make it stop.

To prevent the foam from breaking and collapsing after re-construction after static stop.

5. Attention should be paid to the influence of air temperature during the construction of foamed concrete. When the air temperature is below 10 degrees, a foaming agent with high stability and suitable for winter application should be selected.

When the air temperature is lower than 5 degrees, it is recommended to use early-strength composite Portland cement in addition to an excellent foaming agent. If conditions permit, a simple plastic greenhouse can be built.

6. Construction in summer requires main moisturizing and maintenance. There are two ways to choose, one is to cover straw curtains, reed mats, sacks, sawdust, wet soil, and wet sand, and the other is to cover with plastic sheets

Cancer cells can "stretch out a big hand" and take away the mitochondria of immune cells. The Harvard Medical School research team cultured mouse and human breast cancer cells and immune cells, such as killer T cells, and used field emission scanning electron microscopy (FESEM) to observe the relationship between cancer cells and immune cells. interactive. Interestingly, they found that cancer cells stick out long nanotubes, typically within 100-1000 nanometers in diameter, each of which connects to multiple immune cells along the way. The researchers used the drug L-778123, which inhibits the formation of nanotubes, for treatment. The higher the concentration of L-778123, the better the treatment effect.

It is used in various high-tech fields, so the market demand for foamed concrete will continue to rise. We are a quality supplier of foamed concrete, please feel free to contact us.
