Change in the Price of Concrete Mixture due to the Addition of Additives : Undergraduate Thesis

Beton je nezamjenjivi građevinski materijal koji nastaje miješanjem agregata, veziva i vode uz prisutnost zraka. Ukoliko se dokaže opravdani razlog, mješavini se dodaju aditivi. Aditivi su dodaci betonu koji utječu na njegova određena svojstva. Pojedine komponente betona su gotovo potpuno istražene, kao što su agregat i cement, dok poznavanje utjecaja aditiva još nije do kraja razjašnjeno. Njihovo korištenje se u većini slučajeva potkrepljuje eksperimentalnim postupcima kako se ne bi dobio kontraefekt, odnosno, kako se ne bi prouzrokovala materijalna i financijska šteta. U radu su obuhvaćene osnovne informacije o betonu i aditivima. Podrobnije su opisane pojedine vrste aditiva uz priložene cijene te je opisan njihov utjecaj na cijenu svježeg betona.Concrete is an irreplaceable building material that is formed by mixing aggregates, binders and water in the presence of air. In case of a justified reason, additives are added to the mixture. Additives are added to the concrete to affect its specific properties. Certain components of concrete, such as aggregate and cement, are almost fully explored, while the impact of additives has not yet been fully elucidated. Their use is in most cases supported by experimental procedures in order not to obtain a counter-effect, that is, in order not to cause any material and financial damage. This paper includes basic information about concrete and additives. Individual types of additives are described in more detail with the prices included. Their impact on the price of fresh concrete is also described
