Bottom ash

In this study, experimental results on mesoporous zeolite preparation from a common solid waste, the rice husk ash by a top-down and bottom-up approach were reported. In top-down method, the consecutive treatments of zeolite by acid and alkaline in the presence of a cationic surfactant (CTAB) successfully generated mesopores in the zeolite.

The Quaternary Zarloukh Bentonite –Tuff (ZBT) deposit occurs within the Hemrin South Mountain, northern Iraq. The ZBT deposit occurs as depression-filling exposed on the erosional surface of the siliciclastic Pliocene Muqdadiya Formation and covered by an overburden of recent sediments. The thickness of the studied industrial bentonite bed is ~80−100 cm, occurring at the bottom of these depressions, covered by ~3−4 m thick bedded volcanic tuff, which also contains many 10–12 cm thick bentonite layers along its bedding planes.

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.

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.
