Abstract

A number of polymer types have been studied as yet for various applications such as bridges, decks, floors, mortars, grouts, repair etc. Appropriate polymer must be used for obtaining the desired properties. Furthermore, factors like; polymer/cement ratio, water/cement ratio and curing conditions affect the properties of concrete significantly. The main aim of this study is to observe the effect of polymer modification of glass pebble cementitous mortars, applied for architectural finishes i.e. pool interior surfaces, on ASR. Expansions are monitored by accelerated ASR test method (ASTM C 1260) for the mortars modified by three types of polymers or polypropylene fibers. Since polymers are susceptible to high temperature, the temperature of the solution is lowered to 60 degrees C. Mechanical properties of mortars containing glass pebbles were tested prior and subsequent to NaOH solution exposure. The results reveal that ASR expansion reduced with polymer modification
