摘　　要：[ Objective ] The study aimed at analyzing the solidification reaction in solidified sludge matrices through the variation of water content. [ Method] Firstly, the original sludge was solidified by different masses of cement and dry stone powder, then according to the changes of water content in the solidified sludge matrices, we discussed the effects of various cement and dry stone powder masses on the solidification reaction in the solidified sludge matrices at different time. [Result ] In the solidified sludge matrices, water content decreased with reaction time, and the larger the solidifying agents＇ mass, the lower the water content. The solidification reaction occurred mainly in the first seven days according to the changes of water content, and relative water content increased with reaction time. In addition, the solidification reaction was accelerated due to the increase of the solidifying agents＇ mass, and the types of solidifying agent had an important effect on the solidification reaction. [Condusion] The variation of water content could reflect the extent of solidification reaction, and the forecasting formula of the solidification reaction based on the relative water content is suitable for solidified sludge and other polluted soils.[ Objective ] The study aimed at analyzing the solidification reaction in solidified sludge matrices through the variation of water content.
