Summary of the use of aerated concrete equipment at work

At the doorway of many construction sites, it is often seen that the aerated concrete equipment is in constant operation. The construction of a building can not be separated from the pouring of concrete. The aerated concrete equipment with high load also can not turn. After many years of accumulation, the problems are summed up, hoping to be helpful to everyone.

 

First, excessive aeration: excessive aeration refers to the aeration reaction of aluminum powder in the production of aerated concrete equipment pouring process is too early, or too fast.

 

Secondly, too slow gas generation: slow gas generation is basically the opposite of too fast gas generation, which often occurs in the process of pouring slurry expansion difficulties, not to the due height or other damage.

 

Thirdly, bubbling: This phenomenon usually occurs when the slurry expands to a certain height or after the end of gas generation, bubbles appear on the surface of the slurry or bubbles appear under the surface of the slurry, then the bubble bursts and the gas dissipates.

 

Fourth, boiling: boiling is due to the unstable structure of the bubble and the formation of a comprehensive destruction phenomenon, in the production of aerated concrete equipment formula using cement as a single-calcareous material, cement-slag-sand aerated concrete, more frequent than other aerated concrete. Aerated concrete with low volume density is easier to produce than aerated concrete with high volume density.

 

Fifth, uneven gas distribution: aluminum powder is not evenly stirred.

 

Sixth, slurry thickening too fast: foaming agent, aluminum powder too much.

 

Seventh, thickening of slurry is too slow: the proportion of foaming agent and aluminum powder is too low.

 

Eighth, shrinkage and subsidence: during the foaming process, the bubbles are too large and the rest time is too short.

 

Ninth, collapse mode: less rest time.

 

The above nine are summarized in the work of aerated concrete equipment, and sometimes some problems are not very common, so you just need to know about it, if there is a problem, you can start from these aspects.
