Abstract: A composition that is a reaction product of two or three moieties. The first moiety (A) is a nonpolymeric, multi-functional moiety or combination of mono- or multifunctional moieties that adsorbs onto a cementitious particle. The second required moiety (C) is a linear or branched water soluble, nonionic polymer that is capable of providing dispersing capability. A third moiety (B), if present, is a nonpolymeric moiety disposed between the first and second moiety, to connect the first and second moieties.

Abstract: A dry cast article and method for making the same, wherein the dry cast article includes an oligomeric dispersant that is a reaction product of two or three moieties is provided. To make a dry cast article, hydraulic cement, water, coarse aggregate, fine aggregate, optionally a surface active agent/air entraining agent, and an oligomeric dispersant are mixed and used to form a dry cast article from the mixture.

A third moiety (B), if present, is a nonpolymeric moiety disposed between the first and second moiety, to connect the first and second moieties.

Abstract: A cementitious formulation comprising a cement and an oligomeric dispersant is provided. The dispersant is a reaction product of two or three moieties. The first moiety (A) is a nonpolymeric, functional moiety that adsorbs onto a particle, and wherein one or more A moieties together contain at least two residues to provide attachment of the dispersant onto a particle to be dispersed. The second required moiety (C) is a linear or branched water soluble, nonionic polymer that provides the dispersing capability. A third moiety (B), if present, is a nonpolymeric moiety disposed between the first and second moiety, to connect the first and second moieties. A method is provided for dispersing a cementitious formulation comprising a cement in water, including providing in said cementitious formulation the above oligomeric dispersant.
