POVZETEK

Z vpeljevanjem proizvodnje jeklenih in polipropilenskih vlaken sta tudi pri nas možna razvoj in uporaba mikroarmiranih betonov. Do sedaj ugotovljeni rezultati preiskav teh betonov kažejo, da so primerni za širšo uporabo v gradbeniški praksi in da jih je smiselno upoštevati že pri projektiranju različnih vrst konstrukcijskih elementov. V članku podajamo nekatere najbolj značilne lastnosti strjenih mikroarmiranih betonov, pomembnejše rezultate in ugotovitve preiskav konstrukcijskih elementov pri različnih obremenitvah ter nekatere primere uporabe mikroarmiranih betonov pri nas.

SUMMARY

There is a possibility for progress and use of fibre reinforced concrete in our construction practice because the steel and polypropylene fibres are produced by our own production. The results of investigations of fiber reinforced concrete show that this concrete is acceptable for the use and therefore it may be taken into account when the structural members are designed. In the paper some of the characteristic properties of hardened fibre reinforced concrete, more important results and conclusions of the investigations of structural behaviour of fibre reinforced members and some applications of fibre reinforced concrete in our construction practice are discussed.
