Abstract
Beton je jedan od najzastupljenijih materijala današnjice sastavljen od cementa, agregata i vode. Provedena su ispitivanja na svježem i očvrslom betonu. Zamiješano je ukupno šest mješavina sastavljenih od dva granulometrijska sastava i tri vodocementna omjera. Jedan granulometrijski sastav je kontinuiran dok je drugi diskontinuiran odnosno nedostaje mu jedna frakcija. Vodocementni omjeri u mješavinama su: 0,50, 0,55 i 0,6. Udio cementa je jednak u svim mješavinama što znači da se mijenjao udio agregata i vode. Ispitivanja provedena na svježem betonu su ispitivanja konzinstencije, gustoće i sadržaja zraka. Ispitivanja na očvrslom betonu vrše se kako bi se ispitao modul elastičnosti. Za ispitivanje sekantnog modula elastičnosti potrebno je ispitati tlačnu čvrstoću uzoraka betona. Ispitivanje dinamičkog modula elastičnosti provedeno je metodama rezonantne frekvencije i ultrazvukom. Za ispitvanje dinamičkog modula elastičnosti ultrazvukom potrebno je odrediti dinamički Poissonov koeficijent metodom rezonantne frekvencije. Prema analizi ispitivanja diskontinuirani granulometrijski sastav daje veće rezultate modula elatičnosti pri manjem cementnom omjeru dok je za veće vodocementne omjere veći rezultat kontinuiranog granulometrijskog sastava.
Abstract (english)
Concrete is one of the most used materials of today made up of aggregates, cemet and water. Investigation on fresh and hardened concrete were conducted. In total six mixtures were mixed with two aggregate gradings and three watercement ratios. First one aggregate grading is continuous and second one is discontinuous aggregate grading. Watercement ratio in mixtures are 0,5, 0,55 i 0,6. The proportion of cement is the same in all mixtures, which means that the proportion of aggregates and water is changed. Tests conducted on fresh concrete are tests of consistency, density and air content. Tests on hardened concrete are used to examine the elastic modulus. For the testing of the secant modulus of elasticity, it is necessary to examine the compressive strength of the concrete samples. The dynamic modulus of elasticity testing was performed by resonant frequency method and ultrasonic pulse test. According to the assay analysis, the discontinuous aggregate grading gives higher results of the modulus of elasticity at a lower watercement ratio, while for higher watercement ratios is higher the result of the continuous aggregate grading.
