ABSTRACT:
The invention relates to shaped solid articles manufactured with a hydraulically setting composition comprising water, hydraulic binders and reinforcing fibres and moreover process fibres in an amount of 0-10 wt % with respect to total dry mix and fillers in an amount of 0-50 wt % with respect to total dry mix wherein the reinforcing fibres comprise from 0.1 to 5 wt % with respect to total dry mix of highly crystalline polypropylene fibres possessing a fibre breakage strength of over 490 N/mm.sup.2, having Q<5 and 97<HI<100, and 94<IPF<100, Q being the ratio of weight-average molecular weight to number-average molecular weight, HI being the boiling n-heptane insoluble content in wt % with respect to the total polymer and IPF being the isotactic pentad fraction in mol %.
