Repairing concrete structures using composites

In summary, Reno Nza, a mechanical engineer looking to transition into the field of repair and reinforcement of structures using composite materials, specifically carbon fiber, is seeking data and information from the community. The conversation covers the various factors that need to be considered when choosing a repair method and materials, as well as the resources available online to learn more about composites and their applications in repair work.

I've been searching for a while, but all the knowledge related to this field seems to be developed on field, so, does people here has any data related to such kind of repair ?

I'm mechanical engineer whiling to relocate my field of actuation to this area, repair and reinforcement of structures using composite materials, more specifically, carbon fiber as I've already seen it being used for such kind of applications.

Hope people here can help,

Regards,

Hello Reno Nza,
welcome to PF

A good field to be in - composites.

Every repair would be different. Surface coverings, crack repair, stresses, environment, accessability, endurance would be just some of the factors to consider when choosing a repair method and materials. Some standards could be applied for similar settings such as home basements or structures, road surfaces. In other particular cases the whole engineering route would have to be taken such as for bridge repair or underground pipes.
You should make yourself familiar with composites and get to know all there is about them.

Here is a pdf that just touches on the subject.

@Reno Nza - you could not have done much research on this subject - there are encyclopedias of information online :

Search on any of :

Epoxy concrete

Epoxy concrete for machine construction .

Epoxy Marble

Fibre reinforced concrete

Carbon fibre reinforced concrete epoxy

I've some personal experience of designing machine components using Epoxy concrete .

Fibre reinforced concrete epoxy has been successfully used to repair railway viaducts in the UK
 

1. What are composites and how are they used in repairing concrete structures?

Composites are materials made up of two or more constituent materials with different properties, combined to create a stronger and more durable material. In repairing concrete structures, composites are used as reinforcement materials to strengthen and support the existing structure.

2. What are the benefits of using composites for repairing concrete structures?

Composites offer several benefits over traditional repair methods, including increased strength, durability, and resistance to corrosion and environmental factors. They also have a longer lifespan and can be customized to fit the specific needs of the structure.

3. How are composites applied in repairing concrete structures?

The application of composites for repairing concrete structures typically involves the following steps: cleaning and preparing the surface, applying a bonding agent, placing the composite material, and curing the material. The specific application process may vary depending on the type of composite being used.

4. What types of composites are commonly used for repairing concrete structures?

Fiber-reinforced polymers (FRP) and carbon fiber composites are the most commonly used materials for repairing concrete structures. These composites offer high strength and durability, as well as flexibility in design and application.

5. What are some factors to consider when choosing the right composite for a concrete structure repair?

When selecting a composite for repairing a concrete structure, factors such as the type and severity of damage, environmental conditions, and the desired lifespan of the repair should be considered. It is also important to consult with a professional to determine the most suitable composite for the specific repair project.
