The Relationship of Water-Cement Ratio to the Strength of Cemented Tailing-Waste Rocks

Abstract:

Based on the experimental materials including waste-rocks and tailings are provided by a certain iron mine, designed orthogonal test about the strength of cemented filling body, got 42 groups and 126 dates in total. The results indicate that negative power exponent relationship is showed between the compressive strength and water-cement ratio; meanwhile, the relationship conforms to Arioglu prediction model. The fitting equation is of great significance as well as high precision in fitting results. It also indicates that the model has some applicability and reliability for predicting the strength of cementing filling body, and can be used to preliminary estimate the engineering design parameters in actual filling.
