Abstract

Concrete barriers are being designed as alternatives to conventional systems used as landfill liners. The concretes are made from mineral wastes and are expected to be cheaper and more effective than current systems. To predict the performance of the barriers, transport modeling is used. The processes of advection, diffusion, and adsorption are included in the model. Laboratory experiments have been carried out to determine the properties of the concrete mixtures and large site trials have been carried out to test the model using the material parameters obtained. Confidence limits for the results have been obtained by running the model with successive data sets representing extreme values of the input data. The observed results from the site trials generally fall within the expected limits, but there are some notable exceptions. It is concluded that transport modeling of real landfills is not an exact science.
