Abstract
A composition for pretreating surfaces of equipment for use with an uncured cementitious material, such as uncured concrete, and/or for cleaning cured cementitious material from the surfaces of such equipment includes an aqueous solution with colloidal silica. Pretreatment of a surface with such an aqueous solution may reduce or eliminate adhesion of uncured cementitious material to the surface. Cured cementitious material may be removed from equipment surfaces by wetting the cured cementitous material with the aqueous solution to chemically soften the cured cementitious material, along with abrading the cured cementitious material to mechanically remove the same from the equipment surfaces. Systems for removing cured cementitious material from the surfaces of equipment configured to use with uncured cementitious material include an abrasive element and an aqueous solution with colloidal silica.
