Application


  • Sustainable Brick and Mortar Fabrication: The sodium hydroxide solution is utilized in the geopolymerization of construction debris, offering an eco-friendly solution for creating sustainable building materials. This innovative application not only recycles waste but also significantly reduces the carbon footprint of new constructions (Rahimpour et al., 2024).

  • Water-Based Drilling Fluids: In the oil and gas industry, sodium hydroxide solution is used to modify bovine bone glue, enhancing its properties as an additive in water-based drilling fluids. This research points to improvements in the environmental aspects and operational efficiency of drilling operations (Du et al., 2024).

  • Titration Calorimeters Calibration: The reaction of potassium hydrogen phthalate with excess sodium hydroxide (solution) serves as a standard calibration method for titration calorimeters. This application is essential in various scientific research and industrial applications to ensure accuracy and precision in thermal analysis (Kenealey et al., 2024).

  • Alkaline Activation of Binders: The sodium hydroxide solution is critical in the alkaline activation process of binders used in construction, comparing different materials to optimize performance and sustainability. This study impacts the development of next-generation construction materials (Alves et al., 2024).
