    摘要： To reinforce products made from hydraulic binder agents, fibers of polymerized acrylic nitrile, which are manufactured with a molar concentration of acrylic nitrile units of at least 98%, are used. The fibers advantageously have a strength of at least 50 cN/tex and a breaking elongation of at most 15%. These fibers produce a product after setting having good bending tensile strength and excellent impact strength.

    摘要： The mixture for manufacture of shaped elements of fiber-cement, in addition to minimum 5% by weight of pozzuolanic silicic acid contains also an amount of limestone powder. With this mixture it is possible to obtain a product of high strength properties without tendency to embrittlement respectively to formation of cracks on the surface.In utilizing the mixture for manufacture of shaped elements the latter are moulded from a mixture of aqueous material and permitted to set at 70.degree. to 90.degree. C. during 5 to 12 hours preferably with simultaneous compression.

    摘要： Fibers and yarn and a process for preparing them comprising dissolving in concentrated sulfuric acid a polymer containing at least 75 mol percent of an aromatic poly-(1,3,4-oxadiazole) having the repeating structural formula ##SPC1##In which Ar is ##SPC2## the benzene rings in A or B being substituted or unsubstituted; the linking bonds in A being situated m- or p- with respect to each other, and in B situated m- or p- with respect to X; X being --SO.sub.2 -- or --CO--; and n being 1 or 2. The solution is then spun through a spinneret into a substantially water-free precipitating medium of at least one liquid having the formula (II) ##EQU1## IN WHICH R.sub.1, R.sub.2 and R.sub.3 may be the same or different and are alkyl groups having 1 to 4 carbon atoms, and R.sub.3 may also be H, and in which R.sub.1 and R.sub.2 or R.sub.1 and R.sub.3 may together comprise a divalent alkylene radical, the total number of carbon atoms in R.sub.1, R.sub.2 and R.sub.3 being not more than 8, and in which Z is ##EQU2## a being equal to 1 or 2, b being equal to the valence of Z.
