81	Coping	JP15608398	1998-06-04	JPH11350801A	1999-12-21	ITO SUGURU; KAWAKAMI NOBUO; HASHIMOTO KOICHI; NISHIDA HITOSHI
PROBLEM TO BE SOLVED: To enhance strength by constructing a coping out of cement hardened body made from regular Portland cement, polyacryl amide, phenol resin, epoxy resin and water. SOLUTION: Regular Portland cement, polyacryl amid, phenol resin, epoxy resin and water are mixed and kneaded to form a material for forming a coping. The material is then hardened into a cement hardened body in a mold under a high temperature and a high pressure in a short time to form the coping. The polyacryl amid functions as an assisting agent for coagulating cement particles and enhances the strength of the cement hardened body constituting the coping when it is mixed in the material. The phenol resin functions as an assisting agent for evenly kneading the material with the water content reduced, and it also functions to improve the bending strength and water resistant characteristic of the cement hardened body when it is used together with the epoxy rein. Accordingly, the coping is provided which is improved in its strength rather than conventional concrete or ceramics made copings.

PURPOSE: To obtain a surface porous material, having high mechanical strength and sufficient pores for supporting, adsorbing or heat insulating by providing a ceramic porous layer composed of platy or needlelike crystals formed in the direction nearly perpendicular to the surface of a substrate thereon. CONSTITUTION: A surface porous material has a ceramic porous layer composed of platy or needlelike crystals formed in the direction nearly perpendicular to the surface of a substrate thereon. The ceramic crystals formed on the surface of the substrate in the material are platy or needlelike and formed in the direction nearly perpendicular to the surface of the substrate. Thereby, sufficient carrying of enzymes, etc., and heat insulation can be carried out. Furthermore, since the crystals are formed as described above, supporting, adsorbing or heat insulating effects are sufficiently realized by forming only part of the whole material into the porous layer. As a result, the porous material without deteriorating the mechanical strength of the whole material is obtained. COPYRIGHT: (C)1993,JPO&Japio

97	Porous block having tuff as aggregate, and structure using the same	JP16497597	1997-06-05	JPH10231185A	1998-09-02	NAKADE NOBORU
PROBLEM TO BE SOLVED: To obtain a porous block useful for shore protection block, a block for protecting the face of slope, etc., by sticking a cement paste to an aggregate formed by grinding tuff and hardening the paste into a porous state having open voids. SOLUTION: The cement paste is stuck to the aggregate 2 formed by grinding tuff, is hardened into a porous state having open voids by a conventional method to prepare a porous block 1. Since the porous block 1 having a structure like this contains tuff, which is porous and acidic, the alkalinity of cement is neutralized and the porous block 1 shows weak alkalinity as the whole. Since the aggregate 2 itself has a porous form, the porous block 1 is excellent in water retention and water absorbing properties as the whole. Consequently the porous block 1 useful as a structure for fish bank and a structure for channel is obtained. COPYRIGHT: (C)1998,JPO

99	Porous ceramic for preventing deterioration of fat and oil and its production	JP30251095	1995-11-21	JPH09142950A	1997-06-03	TAKAHASHI SEITARO; EZOE MASANOBU; TSUKADA TOYOHIKO; KOSAKA KENZO; SHIGI MASAHIRO
PROBLEM TO BE SOLVED: To suppress the deterioration of fats and oils by regulating the total amt. of monovalent alkali metal oxides such as Na2 O and K2 O in the compsn. of ceramic after firing to a specified value or above. SOLUTION: Stock for SiO2 selected from among silica sand, feldspar, porcelain clay, etc., stock for Al2 O3 selected from among alumina, kaolin, aluminous shale, etc., and a plastic component selected from among clay, bentonite, monmorillonite, etc., are used as principal components and blended with sodium silicate, potassium carbonate, etc., so that the total amt. of monovalent alkali metal oxides is regulated to >=2.5wt.% after firing. The resultant blend is pulverized to <=300μm average particle diameter with a ball mill, etc., and it is mixed, compacted and fired to obtain the objective porous ceramic having 18-40% apparent porosity. When this ceramic is put in edible oil, the deterioration of the oil is suppressed, the amt. of the oil absorbed in fried food is reduced because the increase of the viscosity of the oil is suppressed and the consumption of the oil can be reduced to 1/2 to 1/3.
100	Humidity-controlling gypsum board	JP23325595	1995-08-19	JPH0959052A	1997-03-04	HANADA KOZO; INOUE HIROO
PROBLEM TO BE SOLVED: To obtain an inexpensive board for construction which has an ability to control its humidity by itself. SOLUTION: Fired hemihydrate gypsum is mixed with a silica gel, when necessary, an admixture comprising an extender and a strength-reinforcing material, and the mixture is formed into boards. Since silica gel having the action of adsorbing and releasing moisture is added to inexpensive gypsum boards, the gypsum boards are imparted with an ability to control the humidity by themselves as a humidity-controllable construction board. When these humidity-controllable gypsum boards are applied to the inner walls of dwellings, offices, schools, hospitals, apartments and the like, they can markedly reduce dew condensation and infestation of molds, mites and the like by the humidity controlling property.
