| Abstract | The primary objective of this research work was to investigate the durability performance of class C fly ash-based geopolymer mortar containing locally available waste clay as source material. The experiments were conducted based on the 20 design trials obtained using response surface methodology (RSM). For this study, the waste clay was collected from few sources of India. The clays in their raw state and after thermal treatment was taken for the investigation. The analysis for optimization was based on parameters such as dry density, compressive strength and water absorption. The optimum combination of clay (with and without thermal treatment) in class C fly ash-based geopolymer mortar was obtained with molarity of NaOH at 7M and 9M with a temperature of curing at 56?C and with clay content of 20%. Durability performance of optimum mix in terms of water absorption, sorptivity, acid attack resistance, sulfate attack resistance, abrasion resistance, drying shrinkage and impact resistance were studied. Thermally treated clay-based specimens exhibited better durability characteristics than specimens with clay in the raw state. |
