Does reinforced concrete have a lifespan of 500 years?

Reinforced concrete does not have a lifespan of 500 years, and the normal service life of a reinforced concrete house can reach 60 years, with brick-concrete structures.

There are several more years. Of course, because of the different uses, its life span is not absolute, and the specific needs to be determined according to the structure of the house.

Because some houses may be affected by the natural environment.

cracking, accelerated destructive force or erosion, weathering, will also affect the service life. In the later stage, if the method of maintenance and reinforcement can be adopted, some defects can be repaired, and the service life can be improved. However, if hidden dangers are found and not dealt with in time, there will be safety hazards in such a house.

Reinforced concrete structureand the difference between brick-concrete structures

1. Some high-rise buildings choose reinforced concrete, and some choose brick concrete, and the main difference between the two lies in the different load-bearing structures. If the former is chosen, it is built of reinforced concrete, which can meet the requirements of bearing tensile force, and is strong and durable, with good fire performance.

2. If you choose a brick-concrete structure, you can meet the load-bearing requirements by building wall columns. And the brick-concrete structure, a small part will choose reinforced concrete pouring, which should be regarded as a mixed structure. It is load-bearing by brick walls, which is suitable for the depth of the bay.

comparatively smaller house structure, and this structure, later load-bearing walls.

It must not be altered, and it is suitable for multi-storey or low-rise building forms.

3. The two also have different advantages and disadvantages, such as the cost of brick and concrete is smaller, but it cannot build high-rise buildings. Reinforced concrete can build high-rise buildings, but the cost is relatively large.

Judging from the current situation, the main structure is only a few decades old, and other places are discounted. Intuitively, the house will have to be repaired 20 years after it was built.

No, is there so much lifespan? This still depends on the quality, and the most important thing is the quality.

How long is the life of reinforced concrete: The general life of concrete is about 100 years. Typically, buildings built with concrete are estimated to be between 50 and 100 years old.

In fact, the life of concrete is not only these 100 years, but in most cases, it is the interference of the environment and the artificial factors, which reduce the life of concrete.

The service life of residential buildings is 70 years.

There is no such thing as a theoretical life span for concrete structures. In the design, the concept of a design reference period can be introduced into the calculation, which is 50 years for general civil buildings. However, the design reference period is not equal to the life of the building, it is only used for load selection and reliability analysis.

In fact, the theoretical life of a normal building is much longer than the design reference period. It is difficult to theoretically build life or theoretical service life, because there are many influencing factors, and at present, only a service life is stipulated, and there is no theoretical calculation.

It can't be that long.

Generally speaking, the proportion of concrete in buildings for different purposes is also different. Makeshift buildings do not require much concrete strength, as long as the concrete can support about two years. So these concrete structures are very fast to build, but they are also very prone to collapse.

Such houses are generally only used as temporary resettlement sites, and they are not built very high.

The second is that there are some replaceable structures inside the buildings themselves, and the lifespan of these buildings is about 25 years. This type of building may be some temporary venues, or some less important buildings, which can be safely lived in during the safe period.

The last type is the ordinary buildings where most people live, and the life span of these buildings is generally more than 50 years, and some of them are relatively long, and can even be maintained for hundreds of years. But we know that the pace of urban renewal and development is very fast, and some buildings may not wait for a hundred years to be demolished and other facilities built, for example, many old residential areas have been transformed into new public facilities recently.

Pay attention to buying second-hand houses.

When buying a second-hand house, if there are conditions, it is best to pay attention to the age of the house. If the house is cracked and leaking, or if the house itself looks old, you should seriously consider whether to buy the house. Even when buying a brand new property, it is important to pay attention to the quality of the property so that you and your family can live with more peace of mind.
