Living in reinforced concrete, have we ever wondered how long the service life of concrete is?

In the city where we live, some people jokingly call it us who live in reinforced concrete. To a certain extent, it is true. Most of the houses where human beings live are reinforced concrete, and we live in such an environment. So how many people have considered the so-called concrete, and how long is its life?

The so-called concrete is portland cement, which is usually formed by the condensation of sand, cement, stones and other substances with a certain amount of water. If you have met other people and cement friends, it will be easier to understand how concrete is made. In our impression, building a house not only uses concrete, but also uses steel bars, so we call it reinforced concrete. The quality of steel bars also affects the service life of the whole concrete house.

Let's talk about the details first. In general, the service life of concrete is very high, and it can be used indefinitely in theory. But this is only theoretical. If put into real life, concrete will be affected by weathering and some rain and snow weather, and the degree of oxidation will be greatly accelerated.

Even in some extreme weather conditions, some buildings made of concrete are destroyed faster. For example, we often see the destruction of cement roads. Because of the excessive pressure, these concretes that could have been used for a long time are destroyed. Moreover, if the concrete on the surface is destroyed and the internal steel bars are exposed, the oxidation degree of steel bars will also be accelerated. Moreover, the cost of repairing these fixed steel bars is very high, even higher than that of reconstruction.

But our ordinary housing, if its material quality is not too bad, is enough for 70 years of property rights. So when building a house, the quality of reinforced concrete is also very important. After all, the workers have worked hard to build the building, and after a few years of living, there will be problems. If something goes wrong, no one can stand it.
