Bottom ash and rice husk 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.

In this study, raw rice husk and bottom ash are used as fine aggregates, while fly ash is used as a binder material in the production of environmentally friendly unfired building bricks. The effect of raw rice husk content on the properties of green building bricks is investigated.

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.
