    Investigation of Sulphate, Alkali and Carbonation Chemical attack in GGBS-Based Geopolymer Concrete and OPC Concrete

    By Akshay Dhawan, Manvendra Verma

    Abstract: This study presents a comparative evaluation of the durability of GGBFS-based Geopolymer Concrete (GPC) and OPC concrete in rapid carbonation, sulphate, and alkali environments. All samples were subjected to three severe conditions are carbonation at 4% CO₂, 25°C and 60% relative humidity, exposure to a 10% sodium sulphate (Na₂SO₄) solution, and immersion in a 10% sodium hydroxide (NaOH) solution for alkali resistance. The durability characteristics were evaluated by the compressive …

    Durability Assessment of Geopolymer and OPC Concretes under Chloride and Sulphate Chemical Attack

    By Akshay Dhawan, Manvendra Verma

    Abstract: The main problems with durable concrete constructions are attacks by sulphates and chlorides on concrete. The primary objective of this study is to evaluate how the strength properties of concrete are affected by the incorporation of fly ash when exposed to environmental conditions involving sulphate and chloride solutions. In this research, geopolymer concrete (GPC) is utilized as a replacement for conventional ordinary Portland cement (OPC). The concrete composition is prepared …
