The paper reports on the results of a research
project aimed at assessing the applicability of aggregate from the NE region
of Slovenia, where igneous rock is found, for the production of
high-strength concrete with high abrasion resistance. A comprehensive
investigation has been carried out into the mechanical properties and
durability of such concrete, and the results of tests are presented for
compressive and flexural strength, modulus of elasticity, abrasion
resistance, freezing and thawing durability, shrinkage strain, creep and
watertightness. The experimental study takes into account concrete mixtures
with W/C varying from 0,30 to 0,70, and different chemical admixtures
ensuring resistance to freezing and strength increase. No supplementary
cementing materials have been used. The study has shown that the
investigated aggregate can be used for the production of concrete meeting
the requirements for strength and durability set by the relevant standards
for concretes used in road pavements.
Članek predstavlja rezultate
raziskovalnega projekta, katerega namen je ocena uporabnosti pohorskega
tonalitnega agregata pri izdelavi visokotrdnega betona z visoko abrazijsko
odpornostjo. Izvedena preiskava je obsežna in zajema mehanske in trajnostne
lastnosti takšnega betona; tlačno in upogibno trdnost, modul elastičnosti,
abrazijsko odpornost, zmrzlinsko odpornost, krčenje in tečenje ter preiskave
vodotesnosti. Študija zajema različne betonske mešanice,kjer vodocementno
razmerje sega od 0.30 do 0.70, uporabljeni pa so tudi dodatki za zvišanje
zmrzlinske odpornosti in plastičnosti. V mešanici nismo uporabili mineralnih
dodatkov. |
