| 摘要 |
<p>An article is produced from a hydraulically solidifying mixture, which mixture contains water, hydraulic binders, reinforcing fibres, processing fibres in the amount up to 10 weight percent, relative to the total dry matter amount, and fillers in the amount up to 50 weight percent, relative to the total dry matter amount. The reinforcing fibres contain from 0.1 to 5 weight percent, relative to the total dry matter content, highly crystalline polypropylene fibres, which fibres have fibre breakage strength higher than 490 N/mm2 and Q < 5, 97 < HI < 100, and 94 < IPF < 100, wherein Q represents the ratio of weight-average molecular weight to number-average molecular weight, HI represents the insoluble content of boiling n-heptane in weight percents and IPF represents the isotactic pentad fraction in mol percents.</p> |
