Experimental Investigations on the Long Term Material Properties of Rubberized Portland Cement Concrete

The paper presents the results of a research work aimed at assessing long-term strength and elastic properties rubberized concrete. parameters were rubber replacement fine aggregates age testing specimens. Compressive splitting tensile concrete cylinders obtained 5 years, coupled with static dynamic modulus elasticity all Additionally, material damping coefficient was assessed by means non-destructive tests. density decreases percentage natural sand aggregates. A significant drop in values after years observed for specimens made moduli decrease increase content. similar trend is compressive strength.
