Abstract: To understand the strength behavior of solidified waste matrices as building materials, sewage sludge as a kind of municipal solid waste had been solidified/stabilized by a binder constituted of Portland cement and stone material powder. Based on the experiment data, a mathematical model relating the strength gain of solidified sludge matrices to the ratio of binder to waste is proposed by statistical analysis. The proposed method is then verified with available test data.
