Abstract:

This paper presents an experimental investigation to enhance damping properties of concrete by using polymeric admixtures. The imperfections of conventional concrete such as low tensile strength, low ductility, and low damping have to be modified and improved. Specifically, polypropylene fibers and styrene butadiene rubber (latex) were selected to use in the concrete mix to achieve high damped concrete. Four different categories of laboratory concrete specimens including plain concrete (PC), fiber reinforced concrete (FRC), polymer modified concrete (PMC), and using fibers in polymer modified concrete (FRPMC) were cast and tested to determine the damping ratio of these concrete categories. Experiments depicted that polymer-concrete composites can absorb the dynamic load energy much faster than conventional concrete. Using these composites in concrete structures increases the position stability of structures subjected to dynamic forces like earthquakes and strong wind due to high damping properties of concrete. © 2011 Taylor & Francis Group, London.
