The blocks undergo a series of processes, including mixing, pouring, stabilization, cutting, and autoclaving. Their unit weight is one-third that of clay bricks, while their thermal insulation performance is 3-4 times higher, their sound insulation is twice as good, their impermeability is more than doubled, and their fire resistance is 6-8 times higher than reinforced concrete. The block's overall strength is approximately 80% of the block's own strength.
