How long can you live in a rural cement board house?

As we all know, in the 50s and 60s, the rural areas were very underdeveloped in all aspects, and the living standards of the peasants were also very low. The houses they lived in were very simple compared to today, basically made of stone and adobe, the roof was only made of a few straws or straw, and the binder between the materials was only mud mixed with other materials, such as mud and rice bran.

For many peasant families, such a house may only serve as a shelter from the wind and rain, and may not have much comfort to speak of. But it may be that the house with such a material structure also gives many rural people a "home" and a place to rest. This kind of adobe house can sometimes be seen in today's rural areas, and its service life is probably about a few decades.

With the passage of time, in the following decades, the countryside also developed to a certain extent, and farmers began to consider more factors in building houses. More and more farmers are choosing cement slabs as the main material when building houses, believing that the houses built in this way are more durable and strong. Cement slabs are mixed with cement, pebbles and steel bars in a certain proportion.

The structure of the cement slab is the same as that of most bridges we see, showing the structure of the inner hollow and the outer cement slab, which can play a good load-bearing role. Cement board houses were once very popular with rural people, and even today, you can still see that many houses in rural areas are cement board houses. So is this kind of cement slab house really as people who admire it think, the quality is very good and safe?

How long is the service life of the cement board house? This may be related to the following reasons.

1. Whether the production of cement board meets national standards is closely related to the quality and service life of rural cement board houses.

Because the cement prefabricated board is closely related to the quality and service life of the cement board house, if the relevant standards of the cement prefabricated board do not meet the national standards, then the quality and service life of the cement board house will be affected. If farmers build cement houses in accordance with national standards, then the service life of cement houses is at least a few decades, and the quality will be much better than those that do not meet the standards.

Second, the service life of rural cement board houses also has a lot to do with whether they are well maintained.

The maintenance of rural cement board houses is related to many factors, such as: construction foundation, temperature and humidity, wind and sand. If the cement board house is in the case of high temperature and humidity for a long time, wind and sun, and rain, then its service life will not be long, so good maintenance plays a very important role in prolonging the service life of the cement board house.

In addition, the choice of the foundation of the cement board house is also very important, which will also affect the quality and service life of the cement board house, so it is necessary to choose the right building foundation.

It is no problem to live in a cement house in the countryside for twenty or thirty years, because our family used to live in this house, and it is still very strong.

The cement slab house in the countryside can also live for a very long time, as long as it is not man-made destruction, or some factors such as nature, there is absolutely no problem for fifty or sixty years.

Personally, I think I should live there for at least 100 years, because I remember when I was young, my grandparents' house was this kind of cement house, and my uncle still lived there until I grew up.

Rural cement board houses can be lived in for a long time, at least forty or fifty years is no problem, and now many rural houses are built with cement boards.

There is no accurate answer to this question, because how many years can you live, there are many factors that affect it, and it is not the only one, and it depends on the quality of cement, and the normal service life of cement is 70 years

It can live for about 10 years, and then it needs to be renovated, and if it is not repaired, the roof will collapse, it will not look beautiful, and there will be water leaks on rainy days.

How many years can you live in a rural cement board house.

Many foundations are also not strong, and many blindly add floors to the roof, and there is no doubt that there is a risk. Some may be required to be demolished and rebuilt in less than 50 years, but a large number can be used for 50, 70 years, or even longer, like urban properties. prefabricated panels.

It has not disappeared from the construction of self-built houses in rural areas, and now there are still people who use it, and some people use it on the lower floor, for example, the house is two and a half or three floors, and the roofs of the lower two floors are prefabricated panels, and the top is cast in situ.

A whole wooden board can carry the weight of a person, if it is glued into a whole with many wooden strips, then it can not bear the weight of a person, it is easy to collapse, so its firmness is very poor, once there is a ** occurs, it is easy to collapse, there are several round holes in the middle that penetrate to both ends, which can not only reduce the use of stones, sand cement these materials, but also reduce the weight of the floor slab, the length of the floor slab must be fixed when it is first prefabricated with a mold, and then there is a prefabricated floor machine.

After the cement prefabricated slab is processed in the processing plant, it can be directly transported to the construction site and installed directly, which is convenient and fast, and it is a construction method in the society at that time. How to fire cement boards? If you first nail a hollow model with a wooden board, then its force is very poor.

In addition, there is a cement board.

The quality of itself is also the processing quality, if it is unqualified, it will also affect the life of the cement board itself. For example, one of the most common problems is that the cement board has cracks and <>

There is no one to go to the house, and within a few years, the house will leak. If no one takes care of it, the leakage area will get bigger and bigger. Water passes through the tile, tile through the prefabricated board, and the board passes through the wall, and the wall painting layer and paint layer are used to foam and fall off, which endangers the safety of the wall.

It is the reaction of three substances during the calcination process, calcium carbonate in limestone.

Calcium oxide is generated.

Calcium oxide reacts chemically with silicon oxide.

Calcium silicate is generated.

Among them, dicalcium silicate and tricalcium silicate are the core substances of cement hardening when exposed to water.

In rural areas, houses built with cement slabs generally have a lifespan of 60 to 70 years. Cement is a powdery water-hard inorganic cementitious material, which can be hardened in air or hardened in water, and fixed and cemented together materials such as sand and gravel.

I think that houses built with cement slabs in the countryside can generally be lived in for more than ten years, but some force majeure factors are not excluded, as long as we maintain them well.

I think that if you build a house with cement slabs, it can generally be used for more than 10 years, and it is also very safe, and it is relatively simple to build in this way, and it is more economical.

The house of the rural cement board house can be lived for about 50 years, and the living time is quite long, which mainly depends on the material of the cement board house, the cement board house is mainly made of cement, sand and some stones, and the steel bar is added in the middle of the stacking, which not only increases the durability of the house, but also increases the quality of the house.

Cement board house is very common in our rural life, such a house is not only comfortable to live in, but also can shelter from the wind and rain, for the cement board house, there will be some small problems after living for a long time, bringing a lot of trouble to the residence, so we can take some measures to extend the service life of the house, first of all, we can apply a layer of lubricant on the steel frame structure used in the construction of the house, this lubricant can not only prevent corrosion, but also prolong the life of the house, This method can protect the basic skeleton of the house and is a good method.

Secondly, we need to clean the cement board house regularly to keep the cement board house clean, and at the same time, we must regularly check the condition of the house to see if there are cracks in the house and whether there is mud falling. The last thing we need to do is to choose better quality cement and sand when building a house, so that the quality of the house can be better, the service life is longer, and we can live safer.

Rural cement house is very common in life, it is not only ***, but also very comfortable to live, can shelter from the wind and rain, and also has the effect of warm in winter and cool in summer, the cost of the rural cement house itself is not very high, suitable for most people in rural areas, and it is more convenient to live, therefore, it is suitable for most of the living and use, when we live, we should also maintain good living habits, so that the cement board house can be kept longer.

A cement slab house in the countryside can be lived in for about 10 years; When building a house, the roof should be waterproof and moisture-proof materials, and the roof can be covered with plastic sheeting when it rains.

This kind of house should be able to live for about five years, so it should be made of better materials and protected from direct sunlight.

When the rural cement board house is built about the year, the roof should be waterproof and moisture-proof material, and the roof can be covered with plastic sheeting when it rains.

You can live in it for sixty or seventy years, such a house is relatively strong, but it is not earthquake-resistant, and the use time is relatively long.

Generally, it can live for decades, in fact, the cement board house is very strong, but the hygiene is not very good, and the environment may be unbearable.

It can only live for about 5 years, because the cement slab will gradually dilute with the precipitation of time and wind and sun.

A cement house can be lived in for 50 to 60 years.

The service life of the cement house is relatively long, in the case of normal use, it can generally be used for 50 to 60 years, when you build a cement house, you must remember to choose the building materials of the first day, so that the built house will be stronger, and it can even be used for 70 years.

However, in daily life, cement houses are relatively rare, and most friends will choose to build a frame structure house, which is more solid. Generally, there will be more cement houses built in rural areas, and many families will choose to build a one-story house, so that they can use cement to build a house, the construction cost is relatively low, and the construction is also very convenient.

The material of the cement room

1. Portland cement.

This kind of cement is very common in life, it is mainly based on volcanic ash as the main material, no matter when, the strength of the material is very high, if it is placed in a low-temperature environment, it hardens faster than other materials of cement, and the frost resistance effect is very good, so many cement houses in the north are made of this material.

2. Slag cement.

It can also be known from the name of this cement that it is mainly made from mineral residues, which are mostly generated in humid environments, and slag cement is also like this, with outstanding heat resistance and dissolution resistance. However, the defects of the cement of this material are also very obvious, the shrinkage is relatively large, and in the case of sudden cooling, the cement will have water and cracking.

3. Fly ash cement.

The processing and production cost of cement made of coal ash is significantly lower than that of the other two, and the sulfate resistance of coal ash material is strong, and it will not shrink because of long-term dry environment. However, it takes a long time for the strength of this material cement to slowly increase, and it is precisely because of this that the freezing resistance and heat resistance of early cement are relatively poor.

Before the advent of "Lou Zhai", the houses in our countryside were basically "adobe" houses, and "Lou Zhai" slowly appeared. To put it bluntly, the "floor house" is a prefabricated cement slab, so how long is the life of the cement slab? Let's explore it below.

Cement slabs are now an outdated method of construction. At present, the houses built in rural areas are basically cast-in-place roofs. How is the lifespan of a concrete house determined?

Manufacturing method of cement slab.

Generally speaking, cement slabs have a fixed prefabricated site. In the hollow formwork, after the reinforcement is placed, production begins. After the prefabricated repairs, they can be sold to the farmers who build the houses. There are many problems in the prefabrication of cement slabs, all of which may be quality problems.

1.The quality of the rebar is not up to standard.

It has been 20 years since cement slabs have been used on a large scale, and there are no technical standards for the production of cement slabs. Basically, when I see other people using cement boards, they are all following the trend. In the production process, in order to reduce costs and maximize benefits, it is very likely that inferior steel bars will be used.

If the quality of the steel bar is not up to standard, the service life of the cement slab will be shortened.

2.There is no standard for cement ratio.

When producing cement boards, the ratio of cement and sand is determined empirically, and there is no uniform standard. In this way, the quality of the cement board produced is different. The template removal time is even different.

In both cases, the quality of the cement slab may deteriorate. So how do we determine the life of cement?

3.Look at the cracks.

The roof is generally made of cement slabs, whether it is a one-story or two-story house, cement slabs will be used. It has been more than ten years since the early construction of the cement board house, and most of the cement covered on the cement board will more or less crack. Generally, the smaller cracks are the cement cracks above.

If the crack is relatively large, it depends on whether there is a problem with the cement slab. In this way, the concrete slabs can be seen, but there are also some concrete slab houses, which are more than 20 years old and do not show any cracks. What to do with such a house?

4.Test. Twenty years ago, when farmers changed from adobe houses to brick houses, they were basically cement houses. The time of life has a history of ten or twenty years. In this case, the relevant departments should conduct a scale investigation of all cement house sub.

Determine the structure of the house and the stability of the house. For the houses that need to be reinforced and renovated, a reasonable plan is given. Farmers can only feel at ease if they fortify their houses.

Cement slabs are just a microcosm of over-construction in rural areas. It is not excluded that there are still rural areas that are used when building houses. Because the life cycle of cement slabs is short, they should be excluded from construction as soon as possible.

Therefore, while inspecting the house, the relevant departments should also check whether there is a backward cement board processing plant in their area, and if there is, it must be banned. Make houses in the countryside stronger.
