Abstract:
Interfacial transition zone (ITZ) microstructure o[ rubber reinforced concrete has been
examined hy using Scanning Electron Microscopy (SEM). The ruhber reinforced concrete has
been prepared in the form consisting of various proportions of waste veh ide tires. The effect
of the rubber on interfacial transition zone which exists between tire ruhber and cement paste
has been investigated. A total of () batches of concretes has been prepared. Each batches
consists of six cylinders which makes totally finy four samples of '/>J50x300 111m.
Compressive strength, split tensile strength, unit weight tests and SEM analysis were
conducted on the prepared samples. In this particular study, bonding characteristic and
fracture analysis between rubher tires and cement paste have been investigated. Although
adhesion hetween the rubber and cement paste was weak, roughening interface is formed and
it constructed a mechanical interlock.
