It was found that 12 wt% phenol resins can increase the compressive and flexural strength by 30% and 65% respectively. In addition, the reinforcing effect of phenol resin is higher in Na-PS and Na-PSS type geopolymers rather than Na-PSDS. Two distinct endothermic peaks were detected in DTA curve which can be attributed to the release of water from phenol resin and its final thermal decomposition.  }, keywords = {Mechanical properties,geopolimer,phenol resin,Composite materials}, url = {https://www.ije.ir/article_72049.html}, eprint = {https://www.ije.ir/article_72049_348de41f0919d06a0c685e9cea57c94d.pdf} }
