چکیده
In the era of industry and technology in Indonesia, environmental problems due to waste are that require wise handling. Fly Ash (FA) from PLTU activities Spent Bleaching Earth (SBE) resulting palm oil production process very abundant, thus polluting environment. Indonesia is currently prioritizing physical infrastructure development, which aims improve connectivity encourage economic growth every sector. The development occurs increases use concrete. Concrete has a tremendous impact on environment because most its composition cement. cement manufacture concrete results emission large amounts CO2 gas into atmosphere, causes an increase global warming. can have lower if reduced as much possible by adding mixture FA SBE wastes. This research will utilize normal weights aim determine optimal economically environmentally feasible. applying substitutions show better than bleaching earth compressive strength. substitute for achieve quality planned 15%, while 10%. Keywords: concrete, (FA), (SBE), strength ABSTRAK Kata kunci: beton, kuat tekan beton

Reuse of spent bleaching earth by polymerisation of residual organics.
Spent bleaching earth (SBE) is a waste generated by the edible oil industry that currently has limited options for beneficial reuse. In excess of ∼2 million tonnes per year of SBE is generated world-wide with major quantities available in the middle-east where significant volumes of edible oils are produced. Low pressure compaction followed by heat treatment at 150°C causes polymerisation of th...
