A Comparative Study between Special Concrete and Conventional Cement Concrete in Bridges and Precast Structures

Abstract

Abstract: India is growing fast, especially in construction. Transportation is key for the country's progress. Bridges and elevated roads are crucial for smooth traffic. They need strong concrete to bear heavy loads for years. Regular concrete isn't always strong or long-lasting enough. This paper aims to make bridges and precast structures stronger, last longer, cost less, and be more eco-friendly. It compares normal concrete with special concrete. Special concrete has extra stuff like micro silica, polypropylene fiber, and bacillus subtilis. These boost concrete's strength and durability. The paper looks at how adding these things affects concrete's strength, how much water gets through it, and its tensile strength. Tests on different types of concrete show that special concrete is much better than regular concrete. This study looks closely at these special ingredients and how they make concrete better. It shows how each one helps concrete become stronger, last longer, and improve overall quality.
