Influence of Mineral Additives on the Properties of Concrete in the Marine Environment : Master's Thesis

Morsko okruženje spada među najagresivnije razrede izloženosti okoliša stoga je važno posebnu pažnju posvetiti projektiranju sastava betona. U ovom okruženju, trajnost betonskih konstrukcija se smanjuje jer se javljaju razni fizikalni, kemijski i biološki procesi koji dovode do razaranja betona. Mineralni dodaci upotrebljavaju se za poboljšanje svojstva betona te se postiže veća otpornost betona na kloride čime se produljuje vijek trajanja konstrukcija. U eksperimentalnom dijelu napravljeno je pet mješavina s različitim postotkom mineralnih dodataka na kojima su se provela difuzijska ispitivanja. Cilj rada je istražiti kako mineralni dodaci utječu na svojstva betona koji će se nalaziti u morskom okruženju.The marine environment is one of the most aggressive environmental exposure classes, so it is important to pay special attention to the design composition of concrete. In this environment, the durability of concrete structures decreases as various physical, chemical and biological processes occur that lead to destruction of concrete. Mineral additives are used to improve the properties of concrete against chlorides and extending the service life of structures. In the experimental part, five mixtures were made with different percentages of mineral additives on which diffusion tests were performed. The aim of this study is to investigate how mineral additives affect properties of concrete in the marine environment
