    摘要: A method of treating concrete pipe is carried out by providing an aqueous lime slurry supply having a lime solids content above 35% by weight of the slurry. This is mixed within an amount of dispersing agent and may contain an alkali metal hydroxide so that the slurry has a pumpable viscosity. A spray assembly is located within the interior of the pipe. The lime slurry is pumped from this lime slurry supply through the spray assembly so that the lime slurry is applied to the interior surfaces of the pipe to neutralize acids thereon. Applying the lime spray also provides a protective coating of the lime slurry on the interior surfaces of the pipe.
