Sažetak

The polymer modified concrete is often used for the remedy of existing reinforced-concrete structures. Results of laboratory testing conducted on 20 different concrete mix compositions are presented in the paper. The water-cement ratio, aggregate grain size, and polymer content in concrete, were all varied in the course of the testing. The dependence between mechanical properties of concrete tested by destructive testing and that tested by non-destructive methods was determined, and this by defining the sclerometer index and by measuring velocity of ultrasound impulse.
