Upfront concrete is the cheaper option which sounds good for the people paying for it, but in the long run steel is more economical. Steel bridges are re-buildable, damage to a steel bridge is more noticeable, it takes a shorter time to build a steel bridge and Steel is more durable than concrete. All signs point to steel being the best choice for a bridge to be as effective as possible. “Steel spans last longer than concrete ones. Those built by eight mostly European firms under the PBP are rated for 80-100 years”

High rate of population grow and improvement in the technology forced individuals to move to rural area. As a result, they use more and more personal vehicles for traveling and commuting to urban areas and big cities each day. On the other side, most bridges in Canada and United States by now are more than 50 years old. Therefore, soon or later, rehabilitation or replacement on bridges are unavoidable (John R. Fowler). However, how to manage the bridge rehabilitation or replacement by having minimum effect on traffic is one of the biggest concern for engineers all around the world.

The use of support beams to connect each end may have contributed to bridge supporting power, preventing weaknesses at the ends, adding to complete bridge support. The use of stronger, fast drying glue may have aided in creating stronger connections between the features and bundles throughout the bridge. These stronger connections due to the use of better glue may have allowed for a greater load to be supported before cracking of glue would occur. Lastly, creating a shorter bridge length may have helped decrease area for a load to be supported. Our bridge was much longer than the average of other groups, which had supported higher loads, possibly demonstrating that a shorter bridge would be a factor in supporting higher

This paper explores the construction aspects of arch bridges, specifically the New River Gorge Bridge near Fayetteville, West Virginia. Arch bridges are one of the oldest types of bridges and have been used for thousands of years across the world. These structures can be constructed of stone, brick, reinforced concrete or steel and can span thousands of feet across wide rivers or deep valleys. The construction of arch bridges relies on the concept of compression and begins with the load at the top of the arch, or keystone. The New River Gorge Bridge in West Virginia was completed in 1977 and is a true engineering marvel. Its construction and existence allows drivers and cargo to traverse the New River Gorge efficiently and safely, an otherwise impassable obstacle.

Fiberglass reinforced concrete (GFRC) is most suitable for construction because it is a great material for restoration of old buildings and also used for the exterior of the buildings. It is also being used widely for walls and ceilings. GFRC allow almost perfect replication of building terra-cotta and ornaments. It’s very low shrinkage allows molds to be made from existing structural ornamentation, then cast in GFRC to replicate the original designs. GFRC is lightweight compared to other traditional concrete which is very important for construction. It is highly durable and safe. Next, expensive equipment is not necessary for pouring or spraying GFRC .Fiberglass is inexpensive and corrosion-proof, but not as ductile as steel. It can only be

High compressive strengths are achieved by using a low water-to-cementations materials ratio, requiring the use of water-reducing admixtures to provide adequate workability. High strength concrete offers significant economic advantages over conventional normal strength concrete (NSC) because more slender members can be designed, resulting in reduced material and transportation costs. As structural components become more slender, deflection becomes a more crucial issue, making long-term creep and shrinkage deformations especially important in HSC structures.

Precast concrete is a construction method for casting concrete into a reusable mold. Recently, the number of buildings and infrastructure projects constructed using precast concrete has grown exponentially. Modern day technologies have turned precast concrete into a very durable, sustainable, and quality controlled product. Will precast and modular building systems be the future of sustainable, quality, and economical building methods?

Ferrocement is thin and light weight cement composite, with several unique properties. The addition of fibers to the concrete enhances the strength properties of the composite and transforms the brittle cement composite into more isotropic and ductile material called FRC. But these two materials viz- ferrocement and FRC have some drawbacks. These two materials cannot be employed where high vibration, high tensile forces and high impact are to be resisted. Hence the solution lies in the new composite called fibrous ferrocement, which is the combination of fiber reinforced concrete and ferrrocement. This new composite have some improved mechanical properties, such as toughness, impact resistance etc. Addition of more than one type of

*Prof. S.D. Bhole et al.., ‘Effect of Micro-Silica on Mechanical Properties of Concrete’. The author concludes the effect of partial replacement of cement by silica fume (micro-silica), studies have been conducted on concrete mixes for M40 grade at 0%, 3%, 6%, 9%, 12% & 15% replacement levels of micro-silica (17).

Concrete is a multipurpose and durable of building materials which are most famous and widely used in the manufacturing world. High Performance Concrete (HPC) also named as a concrete mixture, which consists of high ultimate strength, high workability and high durability compared to the concrete produced with conventional method. American Concrete Institute (ACI) defined high-performance concrete as a concrete which meet all special combinations of performance and uniformity requirements that cannot always be achieved by using conventional constituents and normal mixing, placing, and curing practice. The high-performance concrete does not require specific ingredients or specific equipment except careful design and production.

Because of advancements in today’s technology in construction field, many types of bridges are being constructed depending on the requirement and their suitability for the situations.
