Concrete Mix Design Project for Reduced Cement Use

In 2024, the Luang Prabang Hydropower Project aimed to develop a concrete mix that minimizes cement consumption and reduces the heat of hydration, a major factor in thermal cracking. The project utilizes waste materials, specifically fly ash, to maximize resource efficiency while preventing environmental pollution from disposal. By substituting up to 33% of the cement content with fly ash, the mix maintains its designed compressive strength while significantly cutting costs—saving approximately 112 million baht in cement expenses. Furthermore, this initiative reduces Scope 1 carbon dioxide emissions by 2,652 tons of CO2 equivalent, an impact comparable to planting 279,183 trees.
