Do You Know How Resilient Your Concrete Surfaces Are?

Weak structures, especially those made from wood, will not stand a chance in most conditions. Homeowners and contractors need to consider resilient materials such as concrete to give their buildings a better chance of long-term survival.

Resilience in “concrete terms”

””According to the National Infrastructure Advisory Council, resilience is the ability to reduce the duration and magnitude of disruptive occurrences. When it comes to structures, the effectiveness that a resilient building has is based on its ability to adapt to, absorb, anticipate, or recover quickly from a disruptive occurrence.

As someone responsible for designing, planning, or executing buildings, you have to consider the resilience of that structure from the start, and this means selecting the best materials.

Although wood and steel have their advantages, they are not as resilient as concrete. There is no doubt that wood, for example, is a strong, lightweight, and easy-to-use material that does well in cold and hot seasons. It is, however, prone to damage as a result of harsh environmental elements, including fires, pest infestation, and moisture.

Concrete, on the other hand, makes a structure more durable, keeping it strong in cases of disasters. It does not burn, rot, or rust, and it is highly resistant to earthquakes, vibrations, water, fire, and wind.

You should note, however, that concrete blocks may not be enough. If your home is built using mere concrete blocks, you may have a reason to worry. When exposed to a direct attack from a tornado or harsh storm, the hollow concrete blocks will not hold up for long, since they crumble easily.

Modern concrete innovation for increased protection

Concrete, in general, is a good material for building sustainable buildings, but with the innovations in the world of construction, this concrete can be reinforced to provide even better protection against wildfires, hurricanes, floods, snow, and earthquakes.

Reinforced concrete

Concrete works perfectly well in compression or under pressure. However, the results are not as good in tension. To solve this problem, engineers usually cast wet concrete material around steel-reinforced bars, which are tied together to form a cage.

When the concrete is left to set and harden around the bars, the results are reinforced concrete. This particular procedure works well in cases of both compression and tension, meaning that it resists squeezing and bending. The strong steel provides tensile strength, preventing stretching when exposed to strong elements. Think of it this way: The concrete material becomes the matrix, whereas the steel provides the required reinforcement.

Pre-stressed concrete

Reinforced concrete is one of the best construction materials, but just like bare concrete, it also has flaws. The material crack and can be brittle. In strong tension, the reinforced concrete could fail even with the strength of the steel bars, allowing water to seep in.

As the wet concrete sets, the steel bars are pulled inwards to compress the concrete. Alternatively, the rebars can be stressed long after the wet concrete set, just when it starts to harden. This is a cunning trick that engineers recommend to stop cracks.

Fiber-reinforced concrete

This is a specific type of concrete that consists of homogeneously dispersed fiber substances, such as natural fibers, glass fibers, synthetic fibers, and steel fibers. It is meant to reinforce concrete and increase its structural cohesion and strength. It controls shrinkage cracking, providing better shatter resistance. The good thing about fiber reinforced concrete is that it is more affordable compared to the hand-tied rebar.

The strength of structures built with reinforced fibers depends on a few factors. These include (1) the type of fiber used, (2) concentration, direction, and dispersal of fibers, (3) the volume proportion, (4) the diameter of the used fiber, and (5) the length of the used fiber.
