BEHAVIOUR OF PLASTIC STRIP REINFORCED BLAST FURNACE SLAG UNDER TRIAXIAL LOADING CONDITION

Abstract: Most of the civil engineering constructions are going-on by using conventional materials such as sand, other natural minerals and metals etc. But the availability of these materials is limited since the production due to natural cycle is slow. Thus, there is need of material that can replace such conventional material. Blast furnace slag is one of such material which can replace the conventional materials. In this present experiment, the study related to the Blast Furnace Slag (BFS) and plastic waste bottles used in civil engineering works as a way to minimize their disposal and in the direction of sustainable development. The sample was prepared by using Blast Furnace Slag (BFS) and plastic strips cut manually from used and waste plastic water bottles with four different Aspect Ratios (AR) 1, 2, 3 and 4. The experiments were conducted with the different mix ratio percentages 1, 2 and 3. The plastic strips of different aspect ratios 1, 2, 3 and 4 were added with different mix ratios 1%, 2% and 3% with respect to weight of blast furnace slag. Series of un-drained un-consolidate triaxial tests for cell pressure 100 kPa, 200 kPa and 300 kPa were performed on reinforced blast furnace slag. From the test results we observed that deviator stress increases with increase in aspect ratios and mix ratios. Also the shear strength parameters were found to be influenced with the change in aspect ratios and mix ratios.
