摘要
A method for stabilizing gravel, sand, crushed stone, rock and concrete structures which have cracks by injecting a pumpable, low viscous aqueous aerated concrete with a pore volume of at least 20% by volume into the cracks at a low pressure and then increasing the pressure so that the entrained air bubbles escape and sedimentation and hydration occur.
