Analysis of Flexural Strength of Hybrid Fiber Reinforced Self-Compacting Concrete Using Regression Method
摘要
In recent years, much attention has been paid to the development of self-compacting concrete (SCC). We can call it the concrete that flows under its own weight without the need for vibration; it will automatically fill the formwork. In the present experimental work, flexural strength of hybrid fiber-reinforced self-compacting concrete has been analyzed. It is found that when natural coconut fibers are added to concrete at 0.15%, 0.20%, 0.25%, 0.30% by volume of concrete the flexural strength increases up to 5.77 N/mm2 after 28 days of curing. Similarly, adding 0.25%, 0.50%, 0.75%, 1.00% synthetic steel fibers It is seen that when 0.75% steel fibers are added to SCC, the flexural strength gradually increases. The composition of coconut and steel with same percentages i.e. hybrid fiber self-compacting concrete, flexural strength of the beam is increased up to 7.16 N/mm2. It was found that when 0.75% steel and 0.25% coconut fibers are added to the SCC beam, the flexural strength increases.
