Recently, million tons of coal combustion by-products (CCPs) are generated each year from the coal fired power plants. Among these CCPs, fly ash has been used as a substitute for Ordinary Portland cement (OPC) in order to reduce CO2 emission. However, the bottom ash has been mainly disposed in landfill because of its large and heavy particle with irregular coarse shape and that could cause harmful environmentally effects. Hence, we have investigated the geopolymerization of bottom ash under alkali-activated conditions after grinding the received bottom ash to improve its activation quality. We have four kinds of particle size according to its particle diameter (d) through sieving the ground bottom ash: d |
