The effect of CO2 on the strength characteristics of cement composites based on recycled rubber from waste tires

Abstract

Abstract This paper presents the results of a research into the use of a combination of recycled rubber from waste tires as a 100% aggregate replacement in the production of cement composites. The aggregate was replaced with rubber recycled material in two ratios. At a ratio of 50/50 and a ratio of 40/60 fraction 0/1 mm and fraction 1/3 mm. The test specimens were further subjected to CO2 effect in a Lamart laboratory chamber, where CO2 effect was simulated as equivalent to an aging period of 50 years. The presented results show that the effect of CO2 reduces the strength characteristics of the composite compared to the comparative samples.
