Experimental Evaluation of the Mechanical Performance of Geo Polymer Concrete

Abstract

Objectives: To determine the important Mechanical properties and Elastic modulus of Geopolymer concrete (GPC). Methods: Four mix proportions of GPC using two molarities (12 and 14) of NaOH have been used to achieve M25 grade of GPC. Compressive strength, Tensile strength, Flexural strength and Young's Modulus (E GPC ) tests have been performed as per Codal provisions. Findings: The modulus of elasticity of GPC (E GPC ) for the four mixes has been determined experimentally and the average of four values was noted. With the help of this value,5000 random variables have been generated using Monte Carlo Technique and the average E GPC (for 5000 values) has also been determined. Finally, it has been perceived that the elastic modulus of GPC is nearly equal to that of OPC in contrast to the previous studies.
