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

Commodity prices are on track for their biggest rally in more than a century, while fixed-income assets have seen their longest run of outflows as the war in Ukraine adds to inflationary pressures in the global economy emerging from the coronavirus lockdown, according to Bank of America.

"Commodity prices this year are on track to record their biggest gains since 1915." the bank said in its weekly briefing. They cite many factors, such as pandemics, lockdown, civil strife, wars, excessive monetary and fiscal stimulus, and supply chain disruptions, that have led to "historically" high inflation.  

By the same token, it said government bonds were heading for their worst year since 1949, and "negative-yielding bonds will quietly disappear" from the market as central banks embark on a monetary tightening cycle and raise interest rates to tame soaring inflation.  

The prices of many commodities like the foamed concrete are expected to increase in the future.

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
