Svojstva betona visoke čvrstoće s površinski tretiranom drobljenom gumom ; Properties of high strength concrete containing surface-modified crumb rubber
U radu se primjenjuje novi pristup površinske modifikacije drobljene gume pomoću organoglinskih kompozita kako bi se poboljšala slaba prionljivost između cementne paste i drobljene gume. Primjenom FTIR spektara promatrana je promjena funkcionalnih skupina na površini tretirane drobljene gume. Za poboljšanje svojstava korišteni su mineralni dodaci poput silikatne prašine i metakaolina. Provedena su ispitivanja obradljivosti, tlačne čvrstoće, čvrstoće na savijanje, modula elastičnosti, otpornosti na udar te otpornosti na djelovanje sulfata i kiselina. Postignuti rezultati pokazuju da površinska obrada gume dovodi do poboljšanja svojstava betona. ; This study presents a new approach on surface modification of crumb rubber using organoclay composites in order to improve the poor adhesion between cement paste and crumb rubber. The change in functional groups on the surface of modified crumb rubber was observed by FTIR spectra. Mineral admixtures such as silica fume and metakaolin were used as property enhancers. Tests on workability, compressive strength and flexural strength, static modulus of elasticity, impact resistance, sulphate attack, and acid attack, were conducted. The results show that the properties of concrete were enhanced by surface modification.
