Abstract

Mikroarmirani mort visokih uporabnih svojstava je relativno nov materijal u graditeljstvu. Ima izrazito poboljšana mehanička (tlačna čvrstoća, modul elastičnosti i savojna čvrstoća) i trajnosna svojstva (kapilarno upijanje i difuzija klorida) u odnosu na obični beton. U radu je eksperimentalno napravljeno sedam mješavina morta i prikazani su utjecaji vodovezivnog omjera, vrste cementa, omjera agregata i veziva, količine vlakana i veličine frakcije agregata na svojstva mikroarmiranog morta visokih uporabnih svojstava. Eksperimentalno dobiveni mortovi su uspoređeni s materijalima dostupnima na tržištu, te se pokazalo da imaju ista i bolja svojstva.

Abstract (english)

Ultra high performance fibre reinforced mortar is relatively new material in construction. It has better mechanical performance (compressive strength, modulus of elasticity and flexural strength) and durability (capillary absorption and chloride diffusion) than ordinary concrete. Seven mortar mixtures were experimentally made and the effects of water binder ratio, type of cement, ratio of aggregate and binder, the amount of fibre and aggregate fraction size on the properties of ultra high-strength fibre reinforced mortar are presented. The experimentally obtained mortars were compared with those available on the market and they shown the same and better properties.
