Abstract: A method of treating concrete pipe (10) 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 (28) is located within the interior of the pipe. The lime slurry is pumped from this lime slurry supply through the spray assembly (28) so that the lime slurry is applied to the interior surface 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.

Abstract: A composition for a pumpable lime slurry which is adapted for use as a replacement for caustic solutions is formed by combining a dispersing agent in lime and water to form an aqueous slurry. The amount of lime used is between 35 to 55 % by weight of the slurry. The dispersing agent, which is an anionic polyelectrolyte, such as polyacrylic, polycarboxylic acids and alkali metal salts thereof, is added in an amount between 0.1 to 3 % by weight of the lime. To this is added an alkali metal hydroxide of 0.1 to 1.5 % by weight of lime. The order of addition of the alkali metal hydroxide is important. The later addition of the alkali metal hydroxide results in a decreased viscosity so that a lower amount of dispersing agent is required.
