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

The US Commerce Secretary has announced that the US will temporarily lift tariffs imposed on Ukraine during the Trump administration to help Ukraine recover its economy and continue to show support for the Russia-Ukraine situation. "For steel mills to remain an economic lifeline for the Ukrainian people, they must be able to export steel," the Commerce Department said in a statement.

The Biden administration will announce the lifting of steel tariffs on Ukraine for one year.  Ukraine is a fairly small supplier of U.S. steel, shipping about 218,000 tons in 2019, ranking it 12th among foreign suppliers to the United States, the report said. The U.S. Commerce Department noted that the steel industry is uniquely important to Ukraine's economic strength, with one in 13 people employed in the steel industry. 

Affected by the ever-changing international situation, the supply and prices of international bulk foamed concrete are still very uncertain.

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

The negative electrode material is the carrier of lithium ions and electrons during the charging process of the battery and plays the role of energy storage and release. In the battery cost, the negative electrode material accounts for about 5%-15%, which is one of the important raw materials for lithium-ion batteries. The global sales of lithium battery anode materials are about 100,000 tons, mainly in China and Japan. According to the current growth trend of new energy vehicles, the demand for anode materials will also show a state of continuous growth. At present, the global lithium battery anode materials are still dominated by natural/artificial graphite, and new anode materials such as mesh carbon microspheres (MCMB), lithium titanate, silicon-based anodes, HC/SC, and metal lithium are also growing rapidly.
Our company provides anode materials and foamed concrete. If you need to know more anode materials and foamed concrete, please feel free to contact us.
