Coal bottom ash

This study aims to recycle the coal bottom ash (CBA) for making environmentally friendly construction bricks. In the brick proportion, CBA was employed as fine aggregate to replace 0, 30, 50, 70, 85, and 100% of stone powder.

Utilization of Coal bottom ash (CBA) as well as finding the solutions to prevent saline intrusion, meeting the needs of coastal infrastructure development have been considered by the authors of the article for a long time. In this study, the authors focused on analyzing capillary characteristics in order to find a suitable group of CBA particles, which can be applied in the design of foundations with the high ability in restricting or preventing the effects of salt in saline groundwater.

Present, our country is developing Heat power plants with CFB technology. Coal amount after burning will become ash and slag at boiler bottom with average temperature in 600o C and needs to be cooled in 80o C. This cooling equipment system must be imported from foreign countries. Therefore, author group proposed bottom ash and slag cooling technology using indirect water and heat exchange accounting method.

The reactions form chains and rings of alumino-silicate networks in geopolymeric structures. The raw materials used for geopolymerization normally contain high SiO2 and Al2O3 in the chemical compositions such as meta-kaoline, rice husk ash, fly ash, bottom ash, blast furnace slag, red mud, and others. The geopolymer-based material has potentials to replace Ordinary Portland Cement (OPC)-based materials in the future because of its lower energy consumption, minimal CO2 emissions and lower production cost as it utilizes industrial waste resources.
