Debunking Common Concrete Myths

One of the most commonly utilized materials in the world is concrete. Aside from being the most durable and the strongest material, it is also cost-effective. Because of this, more and more homeowners choose concrete as their primary material for any home improvement project.  

Unfortunately, there are also a lot of myths and rumors about concrete that are still spreading on the internet. If you read some of these myths, you might get discouraged from using them. However, you shouldn’t be. 

Today, we’re going to debunk some of the most common concrete myths on the internet. Professional concrete contractors mobile AL can also help you be more informed when it comes to concrete facts.  

Concrete isn’t Environmentally Friendly 

The cement industry emits carbon emissions into the atmosphere. However, concrete itself is not bad for the environment. Since it’s the strongest and most durable construction material on the market, it can last for a long period. This means that there will be little-to-no major repairs, less energy will be consumed, and no additional material will be used.  

Water Can Damage Concrete 

Though concrete isn’t impermeable, water cannot damage it. The truth is that it’s crucial when it comes to finishing the concrete.  

Opposite to what people say, curing isn’t a drying process. It’s a process where you vaporize the water. Because of this, water is needed to strengthen and hydrate concrete during the curing stage.  

Fresh concrete hydration will keep on as long as there is adequate moisture in ideal temperatures. It also stops when the concrete dries out. Typically, it should have a relative humidity of less than 80%.  

In addition to that, fresh concrete that approaches freezing temperatures greatly slows hydration. On the other hand, fresh concrete in high temperatures dramatically loses moisture and can increase the possibility of cracking.  

The longer concrete cures, the more durable and stronger it will be. Because of this, moisture and water are vital in curing concrete.  

Concrete with Higher Strength is More Durable 

Durability and strength don’t mean the same thing. This means that higher strength concrete isn’t more durable. While comprehensive strength is one of the most popular advantages of concrete, it doesn’t determine its durability alone. There are a lot of other factors to consider.  

Meanwhile, the main causes of concrete deterioration are exposure to freeze-thaw cycles, corrosion of reinforcing the steel, and alkali-silica reaction.  

While concrete isn’t indestructible, you can increase its durability by lowering permeability. In addition to that, structural reinforcement doesn’t stop cracking in areas of tension. However, it holds crack faces together. 

Concrete is Impermeable 

The common belief is that concrete is extremely strong that it doesn’t allow liquid to pass through. However, that isn’t the case, Concrete is porous at some level. This means that water can still pass through it.  

To lower permeability, you can utilize mixed designs with a low cement-to-water ratio, well-graded aggregate, chemical admixtures, and much more.  

You can also lower permeability and absorption by using surface treatments, such as sealers. So, if you don’t want your concrete to be permeable, try asking your concrete contractor about these sealers.
