The present invention relates to an additive for hydraulically setting compositions, comprising a colloidally disperse preparation of at least one salt of a mono- or polyvalent metal cation and of at least one compound which is able to release an anion which forms a low-solubility salt with the metal cation, and of at least one polymeric sulphonated dispersant. The additive is suitable particularly as a slump retainer.

Provided are aqueous resin solutions having unique rheologies and products incorporating the same. The water-based materials provided herein are thermo-thickening, and the materials increase dramatically in viscosity (at least 100 times) in a desired temperature range increase (20 C to <100 C) at ambient pressure. Suitable resins comprising a hydrophobic group and a hydrophilic group may be selected from an epoxy resin, a phenol-formaldehyde resin, a polyurethane resin, an acrylic resin, a polyester resin, an acrylic-urethane resin, a melamine resin, a melamine-formaldehyde resin, an amino resin, and combinations thereof. A specific epoxy functional resin/polymer suitable for the resin solutions are prepared by reacting (A) an epoxy pre-polymer of (1) one or more polyols and (2) one or more epoxy functional materials with (B) a di- or polyamine, thereby forming the aqueous thermo-thickening resin solution. The resin solutions are substantially free of cross-linking agents.

The present invention discloses a phosphorylated polycondensate high-performance water-reducing agent with a phosphorylated melamine derivative, instead of a conventional carboxyl group or sulfonic group, as a main adsorption group. The use of aryl alkoxypolyether as a side chain of the polymer provides a strong steric effect to improve the dispersibility and dispersion-retaining properties of the polymer. A polycondensate high-performance water-reducing agent and a method for preparing the same provided by the present invention have excellent overall performance, high adaptability for current low-grade raw materials of concrete, strong market demands, and vast application prospects. Additionally, the polycondensate has an advanced preparation process provided with the characteristics of industrially scalable production, which offers the prospect of a core technology in the field of water-reducing agent of concrete so as to promote development of the industry.
