Popis: U ovom radu je istraženo djelovanje aditiva na cementne kompozite. Proizvodnju betona i cementnih kompozita prate brojni problemi i zahtjevi vezani za povećanje učinkovitosti, za poboljšanje trajnosti i svojstava. Dodatkom aditiva djelomično se ostvaraju ti ciljevi. Danas skoro pa da ne postoji izvedbe nekog betonskog objekta bez primjene aditiva. Najviše se koriste za betonske kompozite kojima je postavljen visoki kriteriji kakvoće tj. onih za koje se traže posebna svojstva. Kod samog odabira aditiva treba obratiti pozornost na njegov volumni udio tj. njegovo doziranje i njegov utjecaj na hidrataciju cementnog kompozita. In this bachelor thesis, the effect of admixtures to cement composites has been investigated. The very production of concrete and cement composites is accompained by a number of problems and requirements related to the increase in efficiency, to improve durability and properties. The admixtures has partially achieved these objectives. Today almost there is no construction of a concrete object without the use of admixtures. They are mostly used for concrete composites for wich a high quality criterion has been set, i. e. those for wich special properties are required. In the case of the admixtures itself, attetintio should be paid to its volume fraction, i.e. dosage and its effect on the hydration of cement composites.
