Abstract |
|
The Steel Fiber Reinforced Concrete (SFRC) is mainly being used to improve the structural strength and reduce the steel reinforcement that is required. Steel fibers of length 60mm and 35mm were used for the test. The specimens were prepared with steel fibers in ratio of 4% to volume of mortar to study the supporting effect of SFRC in a soft rock tunnel. The experiment was done to find the compressive strength of the specimens. The experimental results showed that SFRC can be used instead of plain concrete in a soft rock tunnel because SFRC can withstand large deformations as compared to plain concrete. In the concrete, Blast furnace slag (GGBS), HRWR plasticizer are being used to increase the strength, durability and produce high performance concrete. The specimens casted were subjected to 3 different curing methods namely: Normal Curing, Hot Air Oven Curing and Steam Curing. The results showed that M13 mix showed having 60% steel fiber of 60mm and 40% steel fiber of 35mm gave the best results. |
