<P>PROBLEM TO BE SOLVED: To provide a fiber-containing cement slurry, wherein fiber is uniformly dispersed in a cement slurry without requiring complicated procedures. <P>SOLUTION: The fiber-containing cement slurry has physical properties in which: the viscosity of the cement slurry formed by mixing a cement, water and an additive, as measured with a rotating viscometer, falls within a range of 0.1 (solid line 80) to 3.8 (solid line 82) Pa_s; and the L-flow initial velocity of the cement slurry formed by mixing the cement, the water, the additive, and fiber falls within a range (shaded area S) of 13 (solid line 84) to 120 (solid line 86) cm/s. <P>COPYRIGHT: (C)2013,JPO&INPIT |
