REACTIVE COMPOSITE PERMEABLE BARRIER

摘要

A reactive composite permeable barrier is provided to be manufactured economically and environment-friendlily by recycling waste resources and have an excellent removal ability of heavy metal. A reactive composite permeable barrier comprises fly ash, yellow soil and bentonite. The reactive composite permeable barrier comprises the fly ash of 67.3~90 weight%, the yellow soil of 7~30 weight% and the bentonite of 0.1~5 weight%. The fly ash is one selected from a group consisting of fly ash, bottom ash and a mixture thereof. A particle size of the fly ash is 0.1~3 mm. A hydraulic conductivity of the reactive composite permeable barrier is 10^-3~10^-5cm/s. An unconfined compression strength of the reactive composite permeable barrier is 450~1000 kPa.
