Abstract

Cemented slurry is a mixture of fine materials, cement and water. Fine materials that used in this research are silica flour. Cemented slurry has been widely used in industrial application which the main application is the mine backfill. Previous study only shows the data collection on the materials itself which is lack in information on the behaviour of total stress to the materials due to the temperature increase. Scaled down replication model is designed to test the behaviour of the proposed material whereby the temperature acts as a controlling factor. This research is to investigate the effect of temperature increase during the deposition of cement slurry within narrow walls. The effect of temperature rise in cemented slurry during the cementation, which expands the cemented slurry volume that involves the exothermic reaction between cement and water. The constraint condition in the narrow walls causing the cemented slurry unable to expand thus causes the total stress to increase. By developing new laboratory model which is the narrow walls model, total stress of cemented slurry is observed throughout the curing process during deposition test with variation of temperature range. The expected outcome from this research, the total stress of the deposition material will increase due to the high temperature. Laboratory model is designed and fabricated to investigate the stress behaviour of cemented slurry under the same boundary condition of mining stope.
