Abstract:
Concrete Is Widely Used In Construction For Its Strength, Adaptability, And Ease Of Availability. Despite These Advantages, Durability Under Harsh Environmental Conditions Remains A Significant Concern. This Thesis Examines The Durability Performance Of Four Concrete Mixes: Mix 1 (Conventional M40 Concrete), Mix 2 (M40 With Glass Fiber), Mix 3 (Geopolymer Concrete), And Mix 4 (Geopolymer Concrete With Glass Fiber). The Study Evaluates Critical Durability Parameters Including Water Absorption, Acid And Alkali Resistance, Shrinkage, And Sorptivity. The Addition Of Glass Fiber Improved Micro-crack Resistance And Internal Bonding, While Geopolymer Binders Offered Enhanced Chemical Durability. Among The Mixes, Mix 4 Showed The Most Promising Results, With Reduced Water Absorption, Lower Shrinkage, And Superior Resistance To Chemical Attacks. Sorptivity Testing Further Confirmed That Geopolymer-based Mixes Exhibited Lower Capillary Absorption, Indicating Better Moisture Resistance. These Findings Demonstrate The Potential Of Geopolymer Concrete, Especially When Combined With Glass Fibers, As A Durable And Sustainable Alternative To Traditional Concrete In Aggressive Environments.
