Coating compositions suitable for machined cementitious substrates are provided. The coating compositions provide adhesion to the machined cementitious substrate while maintaining high mechanical film strength. The coating compositions are also compatible with industrial implementation, and exhibit good pot life.

An exterior sheathing cementitious panel which prevents water penetration and air leakage is provided. Methods for manufacturing exterior sheathing cementitious panels with a highly efficient integrated air/water barrier membrane are provided as well.

Disclosed is a highly dense aggregate of brittle material particles having an interface at which the particles are bonded to each other and pores between the brittle material particles structuring the highly dense aggregate, where a porosity which is a volume ratio of the pores with respect to the whole of the highly dense aggregate is equal to or less than 20%, and a volume ratio of the pores communicating with an apparent outer surface of the highly dense aggregate with respect to a volume of all of the pores of the highly dense aggregate is equal to or higher than 65%.

A resin-impregnated boron nitride body includes a polymer-derived boron nitride and a resin. A process for manufacturing such a resin-impregnated boron nitride body includes: polymerizing a boron nitride molecular precursor into a preceramic polymer shaping the preceramic polymer to form an infusible polymer body; submitting the polymer body to a thermal treatment to obtain a boron nitride body; impregnating the boron nitride body with a resin; and curing the resin.

A coil component includes a porous ceramic portion having pores, a coil portion embedded in the porous ceramic portion, and outer electrodes which are provided on an outer surface of the porous ceramic portion and electrically connected to the coil portion. The porous ceramic portion has a porosity of 10% by volume or more and 90% by volume or less (i.e., from 10% by volume to 90% by volume), and the pores are filled with a cured product of a resin composition containing a cycloaliphatic epoxy resin and an acid anhydride-based curing agent.

A process for the preparation of a concrete structure including casting a layer of concrete, application of a waterbased curable resin system on the wet cast concrete layer and subsequently mechanical incorporation of the waterbased curable resin system into the concrete layer. The mechanical incorporation of the waterbased curable resin system into the concrete layer, which can advantageously be combined with trowelling of the cast concrete surface, the adhesion of a subsequent applied coating onto the thus treated concrete layer is significantly improved particularly in relation to peel strength. Further, a coated structure prepared by this process, which is particularly a floor.

A system and a method are provided for inhibiting pyrrhotite-caused damage to concrete structures. The system includes at least one concrete structure, a quantity of migratory corrosion-inhibiting solution, a quantity of concrete reinforcing solution, and a water sealing substance. The concrete structure can be any structure where the concrete aggregate contains pyrrhotite. The quantity of migratory corrosion-inhibiting solution is applied to the concrete structure to prevent further oxidation of pyrrhotite within the concrete structure. The quantity of concrete reinforcing solution is applied to the concrete structure to lower the porosity of the concrete structure and strengthen the overall integrity of the concrete structure. The water sealing substance is applied to the concrete structure to repel water from the concrete structure preventing any further chemical reactions with the pyrrhotite.
