The presently claimed invention provides a coating composition for an antimicrobial coating, and a method for synthesizing the coating composition. A coating method for deposition of the antibacterial coating is also provided. The antimicrobial coating of the present invention is effective in providing antimicrobial function, easy to be manufactured, stable and durable.

Disclosed are a functional Ecostone and a method for manufacturing the same, wherein the functional Ecostone is characterized in that, on the basis of 100 parts by weight of a raw material formed by mixing 30-60 wt % of gypsum, 20-40 wt % of calcium carbonate, and 10-30 wt % of water, 1-30 parts by weight of a rose geranium extract, 2-10 parts by weight of basalt fibers, 2-10 parts by weight of mulberry fibers, 1-30 parts by weight of phytoncide, 1-30 parts by weight of ocher, and 1-30 parts by weight of charcoal are mixed.

The present invention provides concrete-containing compositions, and methods of making and using the same, that allow for the prevention of microbially induced corrosion in concrete. In certain embodiments, the concrete-containing compositions comprise a cementitious substrate, and a formulation of heavy metal-laden, carbon-based sorbent.

A method for performing selective bacteriostasis of a sulfate-reducing bacterium, the method selectively inhibiting proliferation of the sulfate-reducing bacterium by allowing chelated Al to coexist in an environment where the sulfate-reducing bacterium exists, and a gypsum composition containing calcined gypsum (A) and chelated Al (B), in which the chelated Al (B) is contained in a range of 0.01 to 20 mass parts relative to 100 mass parts of the calcined gypsum (A).

Disclosed is a structure of a matrix, reinforced with a plurality of polymeric fibers protruding from at least a portion of the structure surface, the fibers being capable of endowing (attributing) the at least a portion of the surfacewith biological or chemical resistance. In some embodiments, the polymeric fibers, as further discussed hereinbelow, contain or are coated with at least one biological or chemical agent which further contributes to the endowment of biological or chemical resistance.

A shear panel building material that includes a first facing membrane, a core matrix disposed on a face of the first facing membrane, and a semi-rigid or rigid material attached to the core matrix. The core matrix can include microspheres having a size of about 200 microns to about 800 microns, sodium silicate, and ethylene vinyl acetate. In one aspect, the shear panel is substantially free from glue and cement.

The present invention provides an antimicrobial ceramic tile and manufacturing method thereof. A manufacturing method of an antimicrobial ceramic tile comprises: grinding soils into slurries; drying the slurries into powders by hot air; pressing the powders into a green body through a molding machine; dotting or spraying or showering a glaze slurry on the surface of the green body to form an engobe; dotting the glaze slurry on the engobe to form a ground glaze; mixing a surface glaze and an antimicrobial material into an antimicrobial glaze in a weight ratio of 100:510; grinding water and the antimicrobial glaze into the antimicrobial glaze in a weight ratio of 56:45; and dotting antimicrobial glaze on the ground glaze; finally, rapidly firing the ceramic tile and the antimicrobial glaze into an antimicrobial ceramic tile.

This invention provides in one aspect compositions that improve the corrosion-resistance of cementitious materials. In certain embodiments, the compositions of the invention inhibit the growth of acidophilic bacteria thriving in/on cementitious material.
