Lime is used to build houses in rural areas, so which is stronger, lime or cement?

There are many people who will renovate their houses in the countryside or choose to build their own houses in the countryside. But when building a house, many people also choose to use hydrated lime.

and sand, and then add a small amount of cement. This can also make the house stronger, but many people think that cement is also stronger when compared to lime and cement. Moreover, the cost of cement is also relatively low, so lime is slowly fading out of the construction sites of self-built houses in rural areas.

The cost of cement is also relatively low, and many people also say that the role of cement is still very good. And its cost is relatively low, so cement is still deeply liked by many people. People also like to use cement, and they say that cement is also particularly conducive to construction.

And in the process of building their own houses, they will also use a small amount of lime, so many people also feel that lime is more sought after by people. <>

Cement houses are very strong, and I hope that people can also choose the right materials, and sometimes everyone thinks that lime is better, which requires people to choose differently. However, now lime is also slowly fading out of the construction site of self-built houses, and many people do not use lime anymore. They said that cement is more cost-effective and very convenient in the process of building a house.

They say that houses made of cement are also stronger. <>

Lime is also not very good, sometimes cement is also very good, if you use cement when building a house, then it can also build a better house, and it can also make the built house more solid. After all, a house made of lime is not very useful, and sometimes rainwater seeps into it and the hardened lime will collapse, and the house will collapse. I hope that people will also be able to choose cement to build their houses, which will also be stronger.

After all, cement is also very good for building houses, and sometimes it will bring better performance to people, and cement is also particularly strong.

Of course, it is cement, because lime, if it encounters a particularly humid season or when it rains heavily, it will be washed away by water, but lime has the function of killing insects and preventing insects, so people will plaster lime on the exterior wall.

It is definitely stronger to use cement, but lime is cheaper, so most people still choose to use lime to build a house.

Of course, cement is stronger, because cement is particularly dense, so it is particularly strong to build a house.

First of all, lime needs to be used in the underground foundation, first soak the lime with water and turn it into powder, and then sprinkle it in the foundation ditch that has been loosened, and the lime and soil are mixed and tamped to form Panax notoginseng soil, and the lime is getting harder and harder when it encounters moisture on the ground, forming a layer of waterproof and solid foundation. The appropriate amount of lime is added to enhance the solidification of the welding mud, because the lime will be more rigid and hardened after drying in the soil, and the adobe wall will be stronger. Now the buildings are built with reinforced concrete.

The main solidifying substance of concrete is cement, if lime is added to cement, many people build houses, at that time they are using lime, at that time cement was expensive, lime was cheap, lime was also popular, plus the floor was not high, lime at that time has been very popular. But why is lime less used in recent years? Just listen to Xiao Zhao and talk to everyone.

The face ash, even the bottom layer ash, can be said to be completely absent in today's rural areas, which was still in the early years. Nowadays, it is directly scraped putty after painting, and then painted, or directly pasted with wall tiles, etc., which can be said to be completely useless, which has caused the reduction of lime consumption. The building did not disappear for a long time, from the coarse lime that had just come out of the kiln before, to the bags of fine lime that were packaged later.

It is in recent years that lime has completely faded out of the construction market, so what is the reason for the complete disappearance of lime? I think there are several reasons for this. Lime has been widely used for a long time.

According to research, lime was used in China in the 7th century BC, and the most widely used is as a building material. Lime is made of limestone, dolomite, chalk, shells and other ores with high calcium carbonate content, after 900 1100 high temperature calcined cement plant and rarely add the house is basically thatched adobe house, good stone tile house form. They are all single-storey houses, the structure is not so complicated, and it is relatively simple to take lime, take us here, there is a lime kiln more than ten miles away, and the lime is pulled back with a plate cart or ox cart.

In the past, the cost of lime was relatively cheap, the production process was simple and there were many rocks at that time, many manufacturers directly built a large number of kilns for firing lime, the advantages of cement gradually occupied the market, and its solidity was much stronger than lime. The cement has high density, stronger hardness and frost resistance, strong permeability resistance, and better safety and thermal insulation for the building. Houses made of lime used to collapse during heavy rains.

Because the viscosity of lime is not as high as that of cement, and the firmness is not as high as that of cement, and the cost of cement is also very low.

Because of the current social progress, they are building houses with some advanced things, and lime will be used if people's ability and economy cannot reach it before.

Summary. Generally, the ratio is: cement: sand: stone = 1::4, water-cement ratio =, which is expressed by the mass ratio of various materials to each other (with the quality of cement as 1).

Another method of proportioning is expressed in terms of the mass of each material per 1m3 of concrete. For example, a mix ratio: cement 300kg, water 180kg, sand 720kg, stone 1200kg, the concrete 1m3 total mass is 2400kg.

When designing the concrete ratio, the following requirements need to be met:

1. Strength to meet the design requirements of concrete structure;

2. The workability of the concrete mixture that meets the requirements of construction;

3. Meet the durability requirements;

4. Save cement and reduce costs.

Rural building houses cement lime sand proportions.

Hello boss. 1. The sand-cement ratio of the brick wall is 1:1:6, which is 1 kg of cement, 1 male ridge of lime digging, and 6 kg of yellow sand. The purpose of adding lime is to increase the adhesion of the brick to the coagulated material of Sakurasan.

Generally, the ratio is: cement: sand:

Stone = 1::4, water-cement ratio source blind =, which is expressed by the mass ratio of various materials to each other (with the mass of cement as 1). Another method of proportioning is expressed in terms of the mass of each material per 1m3 of concrete.

For example, a mix ratio: cement 300kg, water 180kg, sand 720kg, stone 1200kg, the concrete 1m3 total mass is 2400kg. When designing the concrete ratio, the following requirements need to be met:

1. Strength to meet the design requirements of concrete structure; 2. The workability of the concrete mixture that meets the requirements of construction; 3. Meet the requirements of durable pin cracking; 4. Save cement and reduce costs. Loss Zen.

Now, lime is becoming less and less and cement is becoming more and more popular, at this time, if we still use lime in the mortar for building houses, it will be more expensive than using pure cement, so lime will gradually fade out of the construction site of rural self-built houses. Self-built houses in rural areas are houses built in rural areas, also called country villas. There are many materials used to build a house, and different materials are needed in the process of masonry of the main structure, lime, cement mortar, and medium sand are all indispensable building materials.

The questioner raised such a question when lime plus cement, cement mortar is relatively soft, easy to construct, usually in the self-built house, generally will add appropriate lime, now the self-built house is basically the kind of addition, called the mortar king, this thing also plays a role in lubrication, I don't know if you find that there is a phenomenon in rural housing now, that is, many years ago, almost every family likes to use lime and cement, but now it is rarely used lime. Almost all of them have switched to cement, which is not a phenomenon in individual villages, but is the case in most areas.

Although cement is a building material that cannot be used in the construction industry, it cannot be used for wall construction in the case of cement and mud alone. The adhesion of cement is not large, and the addition of this lime to the mud for building walls is to increase the solidification of its bricks and mud. Lime was cheaper earlier and was mostly lime mortar.

But in the case of lime and cement, there is a big difference. Lime can only harden in air. Cement can be hardened in air as well as in water.

When painting the blank house, do not add lime, otherwise the wall will fall off in blocks after a long time, generally the ratio of cement and fine sand is one to four, the wall will crack if the cement is added too much, and the stucco will crack if the wall is not dry.

First of all, the cement structure should absorb a lot of water before it, and only use cement sand to mix the grout to build the wall, which is easy to dry and not conducive to construction. After the lime is soaked in water, it is mixed with cement and sand to play a lubricating role, and only a small amount of cement can be added to the mortar of lime to achieve the marking of the wall.

In the past, self-built villas in rural areas did use more lime powder. Now the people who use it have beenThere are not many menstruations, but you still need to use some points when you cover them. The subject asks why it is used less now.

To think about this problem, we first have to figure out where lime powder was used in the rural self-built villas, and then talk about why it is used less now. First of all, lime powder should be used in the foundation of the ground, first the lime powder is soaked in small water and then ground into the powder, and then sprinkled in the roadbed pit that has been dug and the soil has already been turned, and the lime powder is mixed with the soil and then rammed to make it produceThirty-sevenSoil, lime powder on the ground when exposed to moisture becomes harder, producing a layer of waterproof, fireproof and firm foundation. The top is to use lime powder when cutting bricks, and mix lime powder in the mud

Then use this kind of mud wall, and it is very strong after being made. Then there is the use of lime powder in the house. Lime powder and mud are mixed with some straw or wheat bran and used as architectural paint powder on the wall.

Often, it is the lime powder that dries to make it waterproof and glow, similar to the meaning of architectural paints used today. In the previous house, the civil structure was selected, and an appropriate amount of lime powder was added to the mud used for the wall to improve the coagulation of the welding mud. Nowadays, the building is built with concrete, and the key condensation substance of concrete is concrete, and if lime powder is added to the concrete, it will greatly reduce the solidification of concrete, <>

This is the wrong target, so the use of lime powder in modern buildings is very rare, only a little as the internal and external walls of the wall scraping lime powder of the structural force is worse than concrete, like many brick houses in the past, the house is made of lime powder, many houses through decades of sun and rain, many of the walls of the house have been cracked, the structural force of lime powder is far inferior to concrete. In today's houses, the walls are all made of wall paint and interior wall putty powder.

glue). Also reinforced concrete.

On the wall also do moisture-proof. For example, if the lime wall is moisture-proof, the plastered ash will fall off after encountering water, and it will be removed after moisture-proofing. The concrete is relatively stable, whether it is made of moisture-proof or wall tiles, it is much better than lime walls.

Therefore, now rural people will use much less lime powder to build houses, all of which are directly used cement and sand, and the structural force should be greatly improved。Nowadays, lime powder is used less, mainly because the cement output has been further improved, China's cement production has long accounted for more than 50% of the world, with the improvement of everyone's daily life, more willing to apply this kind of durable, durable, easy-to-use concrete, who also needs to be as in the past lime powder, mixed with hemp knife. Moreover, now there is basically no lime powder in the wall plastering the wall, and the internal and external walls that used to be plastered with grass and mud are only replaced by concrete, which was used in the pastQuicklime powdercame to paint the wall, and now it has been replaced with putty powderwall coveringsand other new building materials, the foothold of lime powder has been greatly reduced, and it is very rare to see lime kilns that burn lime powder all over the country, and it is not easy to buy lime powder again.

It is due to the fact that some of the materials are more suitable and the quality is better, so they are used less.

Because there are many toxic substances in lime, if you use lime to build a house, it will have an impact on people's bodies.

Because people's living standards have improved now, all houses will be built with reinforced concrete, which will be stronger.

Because the effect of using lime is not very good, most of them will now use latex paint with better effect, so it is used less now.
