This lecture provides an overview of Portland cement production in Thailand, emphasizing its environmental impact and the country’s efforts to achieve net-zero emissions, along with its strategic transition from traditional Portland cement to more sustainable alternatives in response to climate challenges. It introduces current research focused on developing low-carbon concrete through three key approaches. The first approach involves alkali-activated and geopolymer concrete, which utilizes agricultural waste ashes such as rice husk ash, sugarcane bagasse ash, and corn-stalk ash. Rich in silica and alumina, these materials enhance mechanical properties, durability, and sustainability, offering a viable alternative to conventional cement. The second approach explores the use of recycled waste aggregates to replace natural sand and coarse aggregate in concrete. Materials such as granite waste, plastic waste, and crumb rubber provide an eco-friendly solution to waste disposal issues while reducing dependence on natural resources, helping to mitigate pollution, landfill overflow, and resource depletion, thus making concrete production more sustainable. The third approach focuses on carbon capture technologies in construction materials, where innovations such as Graphene Quantum Dots (GQDs) and porous carbon are being integrated into mortar and alkali-activated materials to improve CO₂ absorption capacity. This enables concrete to act as an active agent in carbon sequestration, contributing to the reduction of net emissions in the construction industry. By implementing these strategies, Thailand is making significant progress toward a more sustainable future, balancing environmental responsibility, structural integrity, and economic feasibility in the concrete and construction sectors.
