摘要： PURPOSE:To achieve glazing with high efficiency without thermally deteriorating the surface of cement material with the heat beams by introducing glaze into plasma flame or laser beams and thermally spraying the obtained molten glaze particles and forming a glazed layer or the surface of the cement material having a surface layer made of specified composition. CONSTITUTION:At least the surface layer to be glazed of a molded and hardened cement material is essentially made of hydraulic cement and molten glazy material powder (e.g. glass powder) of sintered effective amount. Granular glaze 4 is introduced into plasma flame 6 or laser beams 7 of a gun for irradiating plasma or laser and melted. The molten glaze particles are ejected and thermally sprayed from the gun and a glazed layer 3 is formed on the required surface of the cement material 2. Joining strength of the glazed layer and the surface layer of cement material and also the inside of this surface layer is improved by this method.

摘要： PURPOSE:To enable glazing with high efficiency without thermally deteriorating the surface of cement material irradiated with heat beams by applying glaze to the surface of cement material which has a surface layer made of specified composition and irradiating this glaze with plasma flame or laser beams and forming a glazed layer. CONSTITUTION:At least the surface layer to be glazed of a molded and hardened cement material is essentially made of both hydraulic cement and molten glazy material powder (e.g. glass powder) of sintered effective amount. The required surface of this cement material is applied with glaze and the applied surface is irradiated with plasma flame or laser beams to form a glazed layer. Joining strength of the glazed layer and the surface layer of cement material and also the inside of this surface layer is improved by this method. When the cement layer essentially made of mineral powder which is selected from among hydraulic cement, the molten glazy material powder of sintered available amount, magnesium silicate mineral powder, active silica mineral powder, aluminum silicate mineral powder and a group consisting of two or more mixtures thereof is utilized as the surface layer to be glazed of the molded material, it is preferable that efflorescence of the above-mentioned surface layer can be furthermore improved.

摘要： PURPOSE:To readily obtain multicolor design having alternately varied coloring design by applying glaze in which color is changed by melting with heating in specific gas atmosphere on the surface of substrate material and irradiating the applied glaze with laser light while alternately varying said atmosphere. CONSTITUTION:Glaze varying color by melting with heat in an atmosphere of gas selected from gas reactive with glaze component and inert gas is applied on the surface of substrate material to be glazed. Next, the glazed surface is irradiated with laser light while alternately varying at least two species of gas atmospheres covering said surface coated with glaze to afford the aimed multicolor design. As said substrate material, all of the substrate materials such as porcelain, ceramic article, metallic article or cement substance, etc., capable of glazing are able to be used. In a case of cement substance molded article, however, as thermal deterioration may be generated at glazing, at least the surface layer to be glazed is preferably hydraulic cement or cement substance composed of powder material vitrifying by melting in an effective amount for sintering.

摘要： PURPOSE:To improve the durability of cured cement and to prevent the contamination of concrete by contacting the surface of an alkali-reactive mineral aggregate with ozone in the presence of water, thereby modifying and stabilizing the surface structure of the aggregate. CONSTITUTION:A silicate aggregate reactive with alkali component (e.g. pyroxene andesite) is immersed in ozonized water (having a concentration of usually 0.05-2%) or sprayed with ozonized water to modify the reactive site of the aggregate and prevent the alkali-aggrefate reaction. The cracking, breakage, contamination, etc., of concrete caused by the formation of silica gel can be prevented by the use of the aggregate.

摘要： PURPOSE:To obtain a result which is approximated to a visual judgement result by processing a picked-up image of a surface to be evaluated and then deciding the extent of contamination. CONSTITUTION:In a graph where an actual wall surface and a photographic material are compared as scale values, scale values are on a straight line which is at 45 deg. to the horizontal in terms of the values of the actual wall surface and a photographic sample and functional inspection is performed to obtain data similar to the wall surface with the photographic sample. When a set of lightness values is divided into two groups based upon a threshold value Lt in the lightness distribution of all picture elements which are inputted to an image analyzing device, the value Lt is so deter mined as to obtain the largest separation between the two groups. Namely, variance sigmaT between the group is omegaS (Ls-La) +omegab(Lb-La) , where omegas and omegab, and Ls and Lb are the picture element ratios and mean brightness values of the low-brightness value group (contaminated part) and high-brightness value group (noncontaminated part) and La is the means brightness of the entirety. The sections of the low brightness value group and high brightness value group are determined with the Lt value which maximizes the found variance.

摘要： PURPOSE:To suppress reactivity of a reactive silica component in a base.silica reactive ceramic product and stabilize the surface structure of the silica component for a long period by bringing the reactive silica component into contact with a hydrogen peroxide solution. CONSTITUTION:A water absorbing ceramic product, e.g. earthenwears or stonewears, containing a silicic acid component and/or silicate component having reactivity with an alkali component is subjected to permeation treatment using dipping, spraying, etc., to modify reaction parts of the reactive silica component and afford a ceramic product with suppressed alkali-silica reaction. Thereby, crack, fracture and surface fouling, etc., by the alkali-silica reaction can be prevented.

摘要： PURPOSE:To enable tiles to keep a constant thickness in the decoration layer and stabilized shades of colors by forming the decoration layer on the green tiles using chelate compounds as liquid pigments. CONSTITUTION:Green tiles 11 which are compression-molded into a prescribed form are coated and impregnated with chelate compounds and calcined. Thus, the chelate compounds develop their colors to form the decoration layer 13 (colored pattern) to a desired depth. Then, the surface of the decoration layer 13 is polished to increase the smoothness and gloss whereby tile product 14 is obtained. According to the present invention, the decoration layer of an always constant thickness and stabilized color shade are obtained regardless of the drying schedule of the green tiles.

摘要： PURPOSE:To obtain large-sized ceramic plate having high strength and excellent freezing damage-proof property without any deformation, by producing sheet with an aq. slurry contg. beta-wallastonite crystal, flux component and fibrous materials, by laminating the sheets, by press-forming the laminate, drying and then, calcining. CONSTITUTION:The sheet is produced with the aq. slurry contg. beta-wallastonite crystal or calcium silicate crystal converting to beta-wallastonite crystal by calcining, and flux component and fibrous material and the sheets are laminated. Then, the sheet laminate is press-formed, dried and calcined. As beta-wallastonite crystal, either of natural and synthetic ones can be used, but synthetic wallastonite obtd. by transiting xonotlite is pref. from the viewpoint of strength. As calcium silicate crystal transiting to beta-wallastonite by calcining, any well- known one can be used but among them calcium silicate crystal consisting of xonotlite as main component is especially pref.
