The cement has been shelved for 50 years, what should I do if the house collapses halfway?

Even if cement does reach its 50-year term, it will not collapse immediately. Today's houses are basically built of reinforced concrete, a material that is unlikely to collapse in 50 years.

As for the quality of the house, the state is now more strictly controlled, and the developer needs to implement a lifelong responsibility system for the quality of the house. That said, no matter how many years you live there, the developer is responsible for any problems that arise, so they will definitely keep the quality of the house in good condition when they build it. Even if the developer runs away and doesn't do anything, the local street property will find a way.

Cement is a powdery hydraulic inorganic cementitious material. Water is added and stirred to form a slurry that hardens in air or water and bonds sand, stones, and other materials together firmly. In home renovation, cement mortar is used to bond floor tiles, wall tiles, masonry, etc.

It not only enhances the adsorption capacity of surface materials and substrates, but also protects internal structures, and can also be used as a screed layer for rough surfaces in buildings. Therefore, cement mortar is an indispensable material in decoration projects.

Many people believe that the greater the proportion of cement in the overall mortar, the stronger its adhesion, so they often disagree with how much cement the decorating company uses. In fact, this is not the case. For example, if the cement mark is too large, the cement will absorb a lot of water when the cement mortar sets.

At this time, if the moisture on the surface of the tile is overabsorbed, it is easy to crack, thus shortening the service life. Cement mortar should generally be mixed in accordance with the ratio of cement sand = 1 2 (volume ratio).

There are many types of cement available in the market, including Portland cement, ordinary Portland cement, composite Portland cement, slag Portland cement, etc. Ordinary Portland cement or composite Portland cement is commonly used for home decoration.

First of all, we have a misunderstanding about the service life of cement, cement is not a food or a battery, and even if it reaches the service life, it will not collapse instantly. It is true that the service life of cement is 50 to 60 years, but we need to know the origin of cement and the composition of our houses. At present, the commercial houses are all reinforced concrete structures, and as long as the main frame is not moved, there is no problem to live for 100 years or more.

The second is that the service life of residential commercial housing land in China is 70 years, which refers to the land use life, not the service life of the house. The house is personal, but the land is state. However, even if the house reaches the end of its useful life, you don't have to worry, you can continue to live in it by paying a certain amount of land use money.

Before the developer develops and constructs, the construction design plan of the commercial housing must be submitted to the relevant institutions for review, and the construction can only be started after the approval is passed. In the calculation of the design of the house and the service life of the house, there are clear calculations to ensure that the structural safety and quality problems of the house occur during the use of the house.

In fact, this problem is unfounded, after all, few people will live in a house for 70 years, because the property right of the house is calculated from the moment the developer takes the land, so the service life of cement is 50 to 60 years, the property right of the house is 70 years, the house is definitely inhabitable for 70 years, and the premise of living for less than 70 years is not valid!

Most of the houses are bricks except for cement, so there is no need to worry about them collapsing.

If it collapses, it will have to be rebuilt, but generally the quality of the non-collapse is still guaranteed.

If you help him halfway, it's actually a matter of no choice, your own problem.

I think if you buy insurance, you can go to the insurance company to make a claim.

Because the validity period means that the best time to use is 50 years, but after more than 50 years, there may be serious quality problems, which is generally a reminder, so it must be overhauled and repaired frequently in the process of living. And when building a house, in addition to using cement, concrete is also used.

Because cement is very strong, and the life of cement is 50 years, which refers to the calculation in the case of some disasters, and for our daily life, there will not be too frequent **, floods and other disasters.

Because the materials used to build a house are not only cement, but also steel and concrete. These materials can make the house strong.

This is because the safe service life is 50 years, but it does not mean that it will collapse immediately after 50 years.

The "50 years" here actually refers to the condition that the cement is completely exposed to the air, and its service life is only 50 years. In fact, in the process of house construction, the construction of the house is very structured, in addition to the cement layer, there are other decorative layers and other corresponding protective layers. Therefore, it generally does not collapse directly.

No, because a reinforced concrete house is not only made of cement, cement is only a part of the materials used to build the house, and it will not shorten the life of the whole house because of this part.

Won't collapse. The main raw material used in the production of cement is stone, and in the process of calcination, glue is produced, which is then mixed with other components. Therefore, even if the cement has reached the end of its useful life, its gluing effect can be maintained for at least a few hundred years.

When the powdered cement is mixed with water and exposed to the air, it will not only restore the inherent properties of the stone, but also be stronger, so most of the walls of the house can be used for hundreds of years.

In fact, it can be said that cement has a lifespan, if it is bought back and not used cement, its "life" is often only a few months, and a long time will affect its use effect. And if it is not stored properly, this storage time will be even shorter. However, many people are more concerned about the storage time of cement, but its service life.

Does the cement built on the house still have a lifespan? There are also some that the general cement validity period can reach 50 years, if it is poor quality cement may only be thirty or forty years, and ***, ** expensive, it may be more than 100 years. And how is the life of this cement measured at 50 years?

This is scientifically calculated without any protection, taking into account the erosion of wind, sun, rain, flood, cement, sand, etc. Therefore, it is not false that cement has a lifespan, but the life span is not fixed, and it is greatly affected by the construction process, technical standards, environmental conditions, etc. Will the built house collapse after the cement expires?

It must be made clear that although cement has a lifespan, it does not mean that as long as it expires, the house built with cement will collapse, because building a house requires a lot of building materials, and cement is only one of them. Even if the cement life expires, the house will not collapse directly, so there is no need to worry about the problem that the cement life will expire and the house will collapse. In fact, in developed countries, there are still many reinforced concrete buildings that are more than 100 years old, which are still intact and can be used normally.

At present, the earliest reinforced concrete building in our country is more than 100 years old and is still in normal use. Of course, as mentioned above, the technical standards of cement and whether the construction of the number of workers are operated according to the regulations have a direct impact on the quality of the completed house. If you cut corners, lower the cement mark, and reduce the amount of cement used during the construction process, it will definitely reduce the quality of the house.

Cement is rarely used alone, and when paired with sand, the quality of the sand must also be up to standard, it must be pure, especially without clay and impurities, and sometimes it needs to be washed sand before it can be used. Therefore, if there is a problem with sand, it will also affect the quality of cement construction. It should also be noted that even if there is no so-called "life" of a cement house, it is normal for the house to need to be maintained and reinforced for a long time.

Rural people also believe that if the house has been inhabited and popular, then the house can maintain a relatively normal state for many years, but if it is uninhabited for a long time, a good house may be dilapidated in a few years. However, this has nothing to do with the quality of cement, mainly if someone lives in it, there will be someone to maintain it, the ventilation is better, and all kinds of pests and termites are less harmful to the house, because there are people in the house. As long as the construction is carried out in strict accordance with the requirements, the cement built house does not have to worry about its lifespan, and it can be used for hundreds or even hundreds of years.

Today, the buildings in cities are basically made of cement, but it is said that the life span of cement is only 50 years, so what will happen to the buildings of the future? Nowadays, most of the self-built houses in rural areas are cement and steel structures, in fact, even if they are more than 50 years old, we can still live in them. After the cement slurry is mixed with other building materials, it will inevitably corrode and differentiate in the air, and it is very likely to form a certain carbonization phenomenon, but this is a very long process, so after only 50 years, there will be no carbonization.

My house is also built of reinforced concrete, and my house is more than 80 years old. In general, cement has no lifespan, in fact, cement can only become a building material after being mixed with other building materials, so it must be inspected before entering the construction site. The service life of the RC structure is definitely longer than the design life.

And the house in the future is not worth much, science and technology are becoming more and more developed, and the emergence of smart home will definitely set off reforms; When the time comes, it's not a question of what you do, but you want to change to a better house, it is estimated that there are very few manpower to build houses at that time, and it basically depends on mechanization.

The 50-year life of cement refers to the life of 50 years that can be maintained in the case of drastic external environmental changes or erosion, which is only a conservative estimate, in fact, the life of domestic residential houses is basically about 100 years, so don't worry. To give a simple example, if you buy a car and drive through gravel or bumpy ground every day, then the life of the car will definitely not be as long as that of a car on a flat road.

In fact, the same is true for the house, if it is just the wind and rain every day, then the impact on the life of the house is relatively small, but natural disasters such as ** are very destructive to cement. In addition, when building houses in China, we use reinforced concrete construction methods, and in the structure of the house, concrete frame shear walls are used, which makes the house more solid and stable, so there is no need to worry about the house collapsing after 50 years.

There should be no rush, society will manage. It will also be strengthened, and now many old communities or old communities have been improved.

In the future, the houses will be demolished when the time comes, and when the time comes, these houses will become dilapidated houses, and the state must uniformly tear them down and give residents a certain amount of compensation.

The state will definitely introduce corresponding policies, so don't worry, I believe that the country will definitely consider it for us and will definitely think of a good way.

It should be demolished and rebuilt, because the house was already in dilapidation by then.

The design life of cement concrete is 50 years. There is a prerequisite here, and that is the service life of the concrete exposed in natural conditions. That is, under natural conditions, after 50 years, concrete will lose its strength due to wind, sun, rain and weathering.

However, in the actual dwelling, whether it is an exterior wall, an interior wall or a floor, there is a corresponding protective layer and decorative surface layer. The concrete is not directly exposed, and the service life is greatly extended.

With the current economic development, housing prices in various cities are also increasing**. In this era of prices, buying a house has become the goal and topic of many young people. However, some time ago, housing prices rebounded, and the purchase restriction order made many people feel the hope of buying a house again, but there are still people who think that house prices will definitely be ** again in the future, after all, people think that the age of construction cement is 50 years.

Although the society now attaches great importance to the optimization of buildings, and there will be many old house decorations, real experts know that such painting and decoration is not very effective. It can only be said that it is a symptom but not a cure, and even because of improper decoration, it is to greatly reduce the service life of the house.

The life of the house we usually talk about is generally the design life, not the actual service life of the house, but the house at the beginning of the design, taking into account all kinds of wind and rain, local geological conditions, and normal use conditions, theoretically 50 years is no problem, or even longer is no problem.

The service life of cement is 50 years, but after 50 years, is it impossible to continue to live? There is no need to worry about this, because the right to use the house is 70 years, so as long as the house is not demolished, it can be used forever. The 50-year service life is only the surface meaning, if the house is properly protected and decorated, then it can continue to be preserved and inhabited.

1. The service life of cement is 50 years, which mainly refers to the exposed ones without any protection

There is a national standard that says that the service life of cement is 50 years, but this mainly refers to the exposure outside, in the room, which can be protected, and there is a protective layer outside the cement, which can extend the service life of cement. Our homes are 70 years, 60 years, 40 years ......Therefore, this is also a representative of defining the service life of cement. Cement can be used over age, mainly depending on the householdHow about the protection of your own home.

2. When the service life of cement expires, it can be reinforced to extend the service life

Now, after comprehensive consideration, the old communities in our country have also come up with a series of rectification measures for the old communities. One of them is to reinforce the old house that has expired, so that the service life of the cement can be effectively extended. If the house has passed the appraisal, then it is time to carry out construction reinforcement.

3. Prevent decoration damage and protect the service life of cement

Now, every household is involved in decoration, and many people practice barbaric decoration, so the damage to cement is also very great. Don't say 50 years, that is, some may be less than 50 years, they may retire early, and protecting the service life of cement has become a crucial event.
