In the pure slurry system, the amount of cement is relatively fixed, and only the cement strength grade still affects the strength of foam concrete.

Portland cement has a wide range of sources, stable quality, economy and good durability, so it is widely used in the foam concrete industry. The third series of sulphur (iron) aluminate cement has characteristics in foam concrete slurry formation, structural stability, and early strength development. Its application has increased year by year, and its application in some special key projects has been successful.
