Geopolymer concrete is widely explored as a green alternative to traditional ordinary portland cement concrete due to its minimal carbon footprint on the environment. It has been widely accepted for limited applications such as precast works. While geopolymer concretes exhibit better mechanical strength performance than traditional concretes. It also poses a challenge in terms of durability when exposed to extreme environmental conditions, such as acidic media, seawater, and sulfates. To address these challenges, a novel solution is to add corrosion inhibitors to the geopolymer concrete, which may enhance mechanical properties, durability, and resistance to harsh environments. This research focuses on the impact assessment of corrosion inhibitors on the properties of geopolymer concrete, which is developed under ambient conditions. The Geopolymer Concrete (GPC) is synthesized using fly ash, and GGBS is activated with sodium hydroxide, sodium silicate, and corrosion inhibitors such as sodium chloride (NaCl) and sodium nitrite (NaNO2). The sodium nitrate dosage was added incrementally by 2% from 0 to 5% for the study. The inclusion of GGBS played a significant role in reducing the setting time of geopolymer concrete and in retaining the shape of the specimen at ambient curing. The mechanical characteristics, including compressive strength and split tensile strength, were evaluated at 7 days and 28 days. The durability characteristics, including chloride penetration and accelerated corrosion, are evaluated after 90 days of curing. The results confirmed a significant improvement in the mechanical and durability properties of geopolymer concrete, making it a promising alternative to traditional concrete in the construction industry.
