Study Mechanical Properties of Self Compacting Concrete (SCC) Containing Glass Fiber Reinforced Polymer (GFRP) and Zeolite

Nowadays, utilization of pozzolanic materials is one of the usual method for improvement of concrete strength. Pozzolanic reactions cause to voids in concrete materials filled and in continue strength and bearing capacity increased. Zeolite is one of the natural pozzolan is found in Iran and can be extracted and processed simply. In present laboratory research, compressive and tensile strength of self-compacting concrete (SCC) contains zeolite and glass fiber reinforced polymer (GFRP) were evaluated. For this purpose, zeolite content 0, 10 and 20 percentage (in weight) and GFRP value 0, 0.5 and 1 % (in weight) of cement amount were considered. Therefore, nine mix design for specimens prepared and compressive strength and Brazilian tests performed. Results of present study showed that zeolite in SCC can increase compressive strength. So that, maximum and minimum bearing capacity values in specimens with zeolite respectively 13.24 and 8.82 percentage are more than unimproved condition. Also, 10% zeolite in specimens (improved by zeolite and GFRP) with 28 days curing is more effectiveness than 20% in compressive strength. In the other side, Variations of tensile strength in improved SCC specimens from the point of view GFRP effectiveness illustrated 1 % GFRP significantly increase tensile strength in specimens (improved by zeolite and GFRP).
