<p><P>PROBLEM TO BE SOLVED: To provide a cement composition for shrinkage-compensating concrete, which is reduced in an excess temperature rise apt to occur in the inside of a large concrete structure or a thick concrete member and reduced in autogeneous shrinkage to reduce cracking due to them and can exhibit good and uniform strength development and to provide a premix cement composition which constitutes part of such cement composition. <P>SOLUTION: The cement composition for shrinkage-compensating concrete comprises normal portland cement, a coarsely powdered water-granulated blast furnace slag having a Blaine specific surface area of 1,500 to 3,600 cm<SP>2</SP>/g, and an expanding component. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
