There are lots of myths being circulated around online in forums, social groups and message boards. There is a lot of fabrication regards concrete restoration and its methods. Just as we used to hear fairy tales in our childhood, the same way the construction industry has a few tall tales of its own. Now is the time for a reality check against these wrongly circulated myths. We will be discussing the most common myths adjoining concrete restoration.
You cannot improve the appearance of the old concrete
Old concrete is likely to fade after few years but its appearance can be improved. You can easily conceal the fading old concrete only if you know how to do it. Concrete staining is one way to go about it. The stain will add rich colors on the faded concrete. Search for professional concrete restoration companies in San Diego County CA, they can help you more regarding this concern.
Concrete tends to stay life-time
Although concrete is considered to be a highly durable material but it will never tend to last forever. Every material has an expiry date to it. Concrete on the other hand is likely to deteriorate due to many outside factors. Over the years, dirt will start to settle on the concrete and if you do not remove them, they might stain the concrete permanently.
If you want to get rid of the debris and the hard to wash stains, then your first priority should hire a professional power washer to clean the dirt almost twice in a year.
Curing concrete means to let it dry
This is a misconception for many house owners that curing concrete means to let it dry thoroughly. Whereas concrete requires water in order to stay to hydrate and gain strength. As the concrete hydrates, new chemical are being formed in the concrete. These chemical compounds are the main reasons for the strength properties and hardening of the concrete surface. So the longer time the concrete takes for curing it becomes stronger and durable.
Anti-freezing Agent- Calcium Chloride
Calcium chloride is not an anti-freezing agent, it is an accelerator. Though concrete can still freeze if it is not properly protected. In low temperature the concrete gains strength at a very slow rate but with the help of this accelerator, the concrete starts to gain strength at an early stage. Try to avoid placing concrete in cold weather or to maintain the temperature you can use insulation foams or curing blankets.
Reinforced Concrete does not crack
Volume changes caused by temperature and dampness cycles are a characteristic piece of a concrete’s life. Concrete restricted from movement may crack since cement is not flexible. Ordinarily, it is the rebar that causes the restriction and permits it to crack. The structural support does not anticipate the cracking but rather holds the break faces together.
Concrete tends to be flat even after it harden
It is not true that the concrete will remain flat after it hardens. It can change shape while settling. A horizontal movement can be caused my moisture and change in temperature in the concrete slab. Due to this curling might occur. Curling is basically the lifting of the concrete slab from the edges at the joints or the cracks.
Concrete is Waterproof
Well, concrete is a solid but like a sponge it is porous. Water and other substance in the form of liquid can pass through it. The liquid might take up to few hours or few months to penetrate through the wall depending upon how porous the concrete is.
Concrete strength is directly proportioned to its durability
Even though compressive strength is an important representation for concrete, different characteristics can be even progressively important for cement in severe conditions.
