    摘要: A multi-functional admixture for simultaneously providing specified characteristics to hydraulic cement compositions such as concrete contains one or more of specified reaction mixtures obtained by specified two processes as well as partially or completely neutralized substances obtained from such a reaction mixture through a specified third process. The specified two processes include initiating a radical copolymerization process of a radical polymerizable monomer mixture containing maleic anhydride and a monomer of a specified kind in a non-aqueous system in the presence of a non-aqueous radical initiator and stopping the radical copolymerization reaction in its midst while the inversion rate of polymerization is at a specified level by adding water to the reaction system to thereby obtain a reaction mixture. The specified third process is for partially or completely neutralizing the reaction mixture.

    摘要: A high-strength hydraulic cement composition contains cement, fine aggregates, coarse aggregates, water and a specified admixture and has a unit amount of water in the range of 120-185 kg/m3. Water and the cement are contained at a ratio of 20-40% and the admixture is contained in the amount of 0.1-3.0 weight parts per 100 weight parts of the cement. The admixture is one or more selected from reaction mixtures obtained by specified two processes and partially or completely neutralized substances obtained from such a reaction mixture through these two processes and also a specified third process. The specified two processes include initiating a radical copolymerization process of a radical polymerizable monomer mixture containing maleic anhydride and a monomer of a specified kind in a non-aqueous system in the presence of a non-aqueous radical initiator and stopping the radical copolymerization reaction in its midst while the inversion rate of polymerization is at a specified level by adding water to the reaction system to thereby obtain a reaction mixture. The specified third process is for partially or completely neutralizing the reaction mixture.

    摘要: An agent for stabilizing air content of hydraulic cement compositions includes graft copolymers obtained by a first step in which copolymers with average numerical molecular weight 5000-50000 are obtained by radical polymerization of a mixture of radical polymerizable monomers containing anhydrous maleic acid and monomers of a specified form, together in an amount of 80 molar % or more and at molar ratio of 40/60-60/40 and a second step in which graft copolymers are obtained by a graft reaction of 100 weight parts of the copolymers obtained in the first step and 7-60 weight parts of polyoxyalkylene monoalkylether and/or polyoxyalkylene monoalkenylether with a block addition of a total of 23-70 moles of ethylene oxide and propylene oxide per 1 mole of aliphatic alcohol with 8-20 carbon atoms. A hydraulic cement composition is produced with cement, aggregates, water, a cement dispersant, an agent for controlling air content and contains an agent for stabilizing air content as described above in the amount of 0.001-0.5 weight parts per 100 weight parts of the cement.

    摘要: A developing device for an image forming apparatus includes a developer carrier such as a developing sleeve having a magnetic field generating device therein which carries and conveys a developer containing toner and magnetic carrier particles. The developing device also includes a first regulating member such as a blade which regulates the developer being carried and conveyed by the developer carrier, and a developer storing section stores developer scraped off the developer carrier by the first regulating member. The developer storing section includes a second regulating member arranged upstream of the first regulating member with respect to a direction in which the developer carrier conveys the developer. The developing device further includes a toner storing section provided adjacent to the developer storing section to supply toner to the developer carrier. A contact condition of the developer carried on the developer carrier with the toner supplied to the developer carrier from the toner storing section is varied in accordance with variation of a toner density in the developer carried on the developer carrier to thereby vary a condition of the developer on the developer carrier to attract the toner. The second regulating member is spaced from the developer carrier such that when a thickness of a layer of the developer on the developer carrier increases due to an increase of the toner density in the developer on the developer carrier, the second regulating member regulates an increased amount of the developer being carried and conveyed by the developer carrier. The magnetic fields, toner speeds, and distances of the regulating members to the developer carrier satisfy predetermined conditions in different embodiments.
