Abstract
This paper presents the results of authors' laboratory testing of the influence of steel fibers as fiber reinforcement on the change of properties of cement composite mortar and concrete type materials. Mixtures adopted - compositions of mortars had identical amounts of components: cement, sand and silica fume. The second type of mortar contained 60 kg/m3 of fiber reinforcement, as well as the addition of the latest generation of superplasticizer. Physical and mechanical properties of fiber reinforced mortars and etalon mixtures (density, flexural strength, compressive strength) were compared. Tests on concrete type cement composites included: density, mechanical strengths and the deformation properties. The tests showed an improvement in the properties of fiber reinforced composites.
U ovom radu su prikazani rezultati sopstvenih laboratorijskih ispitivanja u kojima se istražuje uticaj čeličnih vlakana kao mikroarmature na promenu svojstava cementnih kompozita tipa maltera i betona. Ispitivane su mešavine - kompoziti tipa maltera koji su imali konstantan (identičan) sadržaj cementa, peska i silikatne prašine. Druga vrsta maltera - kompozita sadržala je 60 kg/m3 čeličnih vlakana kao i jedan superplastifikator. Ispitivane su fizičko-mehaničke karakteristike kako mikroarmiranih maltera, tako i etalona (zapreminska masa, čvrstoća pri savijanju, čvrstoća pri pritisku). Ispitivanja na kompozitima tipa betona uključila su određivanje zapreminske mase, mehaničke čvrstoće i deformaciona svojstva. Ispitivanja su pokazala poboljšanje svojstava mikroarmiranih kompozita.
