Abstract

V diplomski nalogi se ukvarjamo s potencialno reakcijo med karbonatnim agregatom in cementnim vezivom. Ugotavljamo vpliv te reakcije na mehanske lastnosti strjenih betonov, izdelanih z različnimi karbonatnimi agregati. V ta namen smo zasnovali tri različne mešanice betona, eno z apnenčastim agregatom A in drugi dve z dolomitnim agregatom B in C. Betone smo izpostavili različnim pogojem pospešenega staranja pri starosti 7 ali 28 dni. Staranje preizkušancev je trajalo 28 dni. Vsak teden staranja smo določili tlačno in upogibno trdnost betonov ter dinamični modul elastičnosti. Dobljene rezultate smo analizirali z vidika potencialnega vpliva alkalno-karbonatne reakcije na mehanske lastnosti betona.

Secondary title: Influence of carbonate aggregate type on properties of mortars and concretes
Secondary abstract: This thesis deals with a potential reaction between carbonate aggregate and cement binder. We try to establish the impact of this reaction on the mechanical properties of hardened concrete made with different carbonate aggregates. To this aim, we designed three different mixtures of concrete, one with limestone aggregate A and the other two with dolomite aggregates B and C. Concretes were exposed to different conditions of accelerated aging at the age of 7 or 28 days. The aging of the test specimens lasted 28 days. Each week of aging compressive and flexural strengths of concrete were determined, and the dynamic modulus of elasticity was measured. The results thus obtained were analysed in terms of the potential impact of alkali-carbonate reactions on the mechanical properties of concrete.
