NUMERICAL ANALYSIS STUDY OF THE EFFECT GEOPOLYMER CONCRETE COMPRESSIVE STRENGTH ON DUCTILITY OF REINFORCED CONCRETE BEAMS

Geopolymer concrete that has polymer formwork is very likely to be used as reinforced material with several advantages. The advantages of geopolymer when compared portland cement are: resistant acidic environments (corrosion resistance), better bond strength reinforcement material, stable at high temperatures, higher fracture energy. Previous experimental studies found the tensile strength, and energy were better, leading hypothesis ductility value was than concrete. identification values based on compressive will carried out in research using finite element method 3D ATENA program. Several specimens 25 MPa, 30 35 40 45 MPa their values. results showed specimen had highest 5.33, while lowest 3.39.
