Sekundarni naslov: | Influence of carbonate aggregate type on properties of mortars and concretes |
Sekundarni povzetek: | 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. |
