144 Method for modifying surface of carbon material JP9440293 1993-04-21 JPH06305858A 1994-11-01 TANABE YASUO; SASAKI YASUYUKI; OBARA HIDEHIKO; IMAKI SUNAO
PURPOSE: To enable modification of the surfaces of carbon materials of various kinds by a simple process under a mild condition without requiring a specific device by bringing fluorine gas into contact with the surface of a carbon material and then bringing a prescribed monomer to the surface of the carbon material. CONSTITUTION: 0.1-50% fluorine gas diluted with an inert gas such as nitrogen or helium is brought into contact with the surface of a carbon material under 1Torr to 2 atmospheric pressure at -70 to 200°C for 1 second to 10 days, then one or more monomers having Alfrey-Price's (e) value of 1.7>(e)>-1.0 handleable in a gaseous state is brought into contact with the surface of the carbon material to cause polymerization reaction on the surface of the carbon material to form a polymer film having several Å to several 100 micron thickness. Optionally, various gases are brought into contact with the end of the polymer to stop the polymerization or further another monomer is brought into contact with the surface of the carbon material and a different polymer layer is formed to give a carbon material having a modified surface of high water repellency and maintaining surface characteristics of ≥100° contact angle with water.

145 Fluidity decline-preventive dispersant for cement composition JP35398192 1992-12-15 JPH06183804A 1994-07-05 ISHITOKU HIDEAKI; MORIMOTO TAKATOSHI; KAWAMURA MASANOBU; NAKAMOTO TOMOFUMI
PURPOSE: To provide a dispersant for cement capable of substantially reducing slump loss, consisting mainly of bisphenol-based condensates which can gradually be adsorbed on cement particles. CONSTITUTION: The dispersant consists mainly of bisphenols-aromatic aminosulfonic acid-formaldehyde condensates (component(s) with molecular weight of 2000-20000 accounting for ≥65wt.% thereof ≤0.97 in the adsorption ratio in a cement-water slurry (comparing the adsorption after a lapse of 10min with that after a lapse of 30 min). To obtain this condensate, (A) bisphenols, (B) an aromatic aminosulfonic acid, (C) formalin and (D) an alkali are made to react at the molar ratio A/B/C/D of 0.5:(1.1 to 1.5):(1.0 to 2.0):(0.9 to 2.1) in an aqueous state at 75-85°C for 10-15hr; and the resulting condensates are treated with a ultrafiltration membrane with the fractionating molecular weight of 100000 to eliminate higher molecular weight components).

PURPOSE:To obtain a fiber reinforced cement-based composite material capable of smoothly carrying out stress transmission from a cement-based material cured body to a continuous fiber and capable of continuously raising flexural offset yield strength without lowering flexural offset yield strength of the fiber reinforced cement based composite material even after causing crack to cement- based material cured body by action of strong external stress on the fiber reinforced cement-based composite material. CONSTITUTION:The objective fiber reinforced cement-based composite material is obtained by joint using a >=1.5vol.% short fiber having >=2.0t/mm<2> tensile modulus and carbon fiber bar or carbon fiber mesh as a reinforcing fiber mixed in a ceramic matrix. In a range in which tensile modulus of a continuous carbon fiber used in the carbon fiber bar or carbon fiber mesh is >=20.0t/mm<2> and the ratio of tensile strength-reinforcing bar is <=0.5%, its hybrid effects are remarkably exhibited.
