Performance of foam concrete block

The density of foam concrete block is 200 ~ 1200 kg/m? ，200~300kg/m？ Ultra-low density block, 400 ~ 500 kg/m3 low density block, 600 ~ 800 kg/m3 medium density block and 900 ~ 1200 kg/m3 high density block.

The absolute dry bulk density of foamed concrete is100, and it is divided into 200, 300, 400, 500, 600, 7000, etc. 1 1 grades from1200 *. According to this density grade, its technical performance is as follows. Standard method for drying shrinkage value of bulk density grade 200 300 400 500 600 700 800 90010001001200.
