Abstract: The present disclosure provides use of a graphene oxide/butyl acrylate/silane composite emulsion as an anti-shrinkage agent of a cement-based material. In the present disclosure, active groups on an isobutyltriethoxysilane molecule reacts with hydroxyl groups on a surface of a mortar to form a layered hydrophobic structure, thereby slowing a water loss in the mortar of the cement-based material and avoiding cracking caused by drying shrinkage. Butyl acrylate can be dehydrated to form polymer fibers with a spatial network to fill pores of a cement paste, thereby limiting the shrinkage of the mortar. Graphene oxide has a relatively large specific surface area and oxygen-containing functional groups on a surface, which can provide growth sites for hydration products, and promote the hydration products to form a regular and dense structure in the form of a template, thus ensuring a strength of the cement-based material.

Abstract: A three-part epoxy grout composition comprises a liquid epoxy blend, a liquid hardener, and a graded particulate aggregate, wherein the dry aggregate particles are pretreated with an applied adhesion promoter in an amount of 0.01 to 5% by weight. The volume of pretreated aggregate particles, when mixed with the epoxy blend and the hardener, comprises at least 70% by volume of the cured grout. Pretreatment of the aggregate by coating with adhesion promoter allows more efficient use of chemicals along with improved strength. Related methods are also disclosed.

Abstract: Dispersion-based ready-to-use grout formulations, methods of making such dispersion-based ready-to-use grout formulations, and the resultant grout products that perform as reactive resin grout products. The grout formulations of the invention at least include a water-based acrylic polymer dispersion binder and a water-based acrylate copolymer dispersion binder, in combination with one or more of an alkaline cross-linker, one or more silane adhesion promoters and/or a micro-fiber filler, along with various other constituents, to provide one-part ready-to-use grout formulations that require no mixing prior to use thereof. The resultant grout products of the invention meet performance standards of epoxy grout products, without requiring mixing of composition parts and without any adverse side effects.
