Potential for Reduced Greenhouse Gas Emissions in Indonesia Through the

抄録

The objective of this study was to determine the potential for reductions in carbon-dioxide emissions in Indonesia by substituting high volumes of fly ash in concrete production and to identify the resulting benefits and challenges. From literature, it is known that fly ash can improve the properties of both the fresh and hardened concrete. High-volume fly ash (HVFA) can further improve workability, heat of hydration, strength, permeability, and resistance to chemical attack. From a power plant located in East Java, it is determined that tons of fly ash are produced annually and about 40 percent are generally sold for use in concrete or other end products.
