<p><P>PROBLEM TO BE SOLVED: To provide a cement molded body reinforcing fiber which can be defibrated and uniformly dispersed in a short time without performing mechanical stirring for a long time upon kneading a cement molded body material such as cement paste, mortar and concrete, not even in the case including kneading water, but also, in the case of dry blending including no kneading water, and can impart an excellent reinforcing effect without damaging the fluidity in being fresh of a cement molded body. <P>SOLUTION: The cement molded body reinforcing fiber is a short fiber to which a treatment agent composed of a polycarboxylic acid ether based anionic compound and polyalkylene glycol is imparted. The total coating weight of the treatment agent is 0.5 to 20 wt.% by a solid content ratio, further, the single yarn fineness of the short fiber is 0.5 to 100 dtex, and also, the aspect ratio of the short fiber is 50 to 1,000. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
