Assessment of the Air-Entraining Effect of Rubber Powder and its Influence on the Frost Resistance of Concrete

Original language description

This research is focused on concrete with rubber powder content exposed to low (freezing) temperatures. Rubber powder serves as an air-entraining agent and should provide better freeze-thaw protection. On the other hand, rubber powder limits the maximum compressive strength of concrete. The main purpose of this research is to find an optimal rubber powder content in order to satisfy needs for the minimal loss in strength of concrete, as well as Increased freezing-thawing resistance. A freeze-thaw test was carried out on five concrete mixes with different factors of several rubber fractions to determine the optimal rubber grading. Specimens with rubber powder were tested for compressive strength, splitting tensile strength, tensile strength, and moduli of elasticity. The specimens with rubber content were tested at laboratory temperature, as well as at freezing temperatures. The influence of rubber addition was assessed on the basis of original and residual values of studied properties after freeze-thaw loading. Resistance to frost damage was determined by utilizing splitting tensile strength and tensile strength tests. Non-destructive methodology was predominantly used to monitor gradual deterioration during the freeze-thaw cycling.
