Is it better to use cement mortar or lime mortar to build a house and build walls? Why?

In the past, self-built houses in rural areas were built with lime, sand, and synthetic mud, and sometimes a small amount of cement was added to them, which was very common in the past. However, now, in the process of building houses in rural areas, few people use lime mortar.

Is lime mortar or cement paste more suitable for building walls? Now lime mortar is rare, and few people use lime in the process of building houses in rural areas, and now they basically use cement slurry.

The cost of lime mortar is relatively low, this situation is determined by calculating the cost, in the past, lime kilns are very common everywhere, lime is very cheap, so everyone builds houses with lime slurry, now lime slowly fades out of the countryside, cement slurry is more and more common, rural houses use two kinds of mortar of ingredients, the firmness of lime slurry is not as good as cement slurry, if lime is added to the cement slurry, it is actually quite good, the cement with lime will be harder, and the cement is easy to get damp to a certain extent, and lime can absorb waterAnd the wind resistance is also particularly strong, which improves the degree of firmness.

Cement slurry and lime slurry can be mixedThe purpose of mixing is to make the cement slurry more lubricating, and the purchase of cement ** is higher, compared to lime is much cheaper. Lime is added to the cement slurry, in order to save cement and achieve the effect of saving costs, lime slurry can be moisture-proof for indoors, and it is not conducive to waterproofing when used outdoors, so in the construction of a house, lime slurry is used for interior walls because of its good water absorption, and can not be used for exterior walls, which is easy to cause water seepage on the exterior wall and will also cause the tiles to fall off.

cement mortar. It is more common to look at rural self-built houses now, and cement mortar is commonly used, of course, lime mortar can also be used. Added cement is more firm, lime slurry and cement slurry are used together, because of strong lubrication, so it can take the lubricating effect, it is more convenient to use, smoother and more labor-saving, in fact, now the cement slurry and lime slurry are not bad up and down, and it can not achieve the effect of saving costs, lime slurry wall, low structural strength, has slowly disappeared in rural construction.

To build a house and build a wall, use cement mortar or lime mortar, this question needs to be considered, in fact, the construction of houses is now generally used to build walls with cement mortar, because cement has good fixation.

I think cement mortar is better because the house is more stable because it is made of this material.

I think it's better to use cement mortar because it's stronger to use, and the two of them actually cost about the same, but it wins because of its excellent water resistance.

Plastering gypsum mortar is a newer, more environmentally friendly and more economical national key promotion product instead of cement mortar, which has the strength of cement, and is healthier and more environmentally friendly than cement, durable, adhesion, not easy to pulverize, no cracking, no hollowing, no powder and other advantages, easy to use, cost saving. The cost analysis is as follows:

In terms of unit price, plastering gypsum mortar is more expensive than cement sand paddle, but plastering gypsum mortar has many advantages, and on the whole, the plastering gypsum mortar cost per square meter is lower than that of cement mortar

1. It basically solves the problem of hollowing, cracks and falling off of the plastering layer. At the same time, the plastering period is shortened, and the efficiency is improved compared with the traditional cement mortar plastering process.

2. The bulk density of plastering gypsum slurry is 1, and the bulk density of cement lime slurry is in, when the plastering thickness is 13 -14, 1t plastering gypsum mixture slurry can be wiped 75 -80, and cement lime mixing slurry can be wiped 45 -48.

3. The labor quota for the process operation required to prepare 100 high-quality veneer wall walls, the labor quota for gypsum mixture, and the labor quota for cement lime mixture. Compared with gypsum mortar, the two reduce a large number of operating procedures and help save about 1 times the labor consumption.

4. It can eliminate the chiseling process on the concrete surface and shorten the plastering period at the same time.

5. Decoration on the plastering gypsum mortar overlay can save decorative coatings and pasting glue, such as 106 paint for general walls, and 106 paint for plastering gypsum walls.

6. The plastering gypsum mortar is strong and hard early, and it is suitable for rushing the construction period.

7. Gypsum mortar has strong bonding properties, which basically eliminates hollowing and cracking, and reduces rework.

8. Gypsum mortar has less ash during construction, which reduces the waste of materials and cleaning labor.

9. Gypsum is more suitable for construction in winter than mortar cement sand paddle, which can save a lot of winter construction insulation costs.

10. Gypsum mortar is a Class A fireproof material, which can improve the fire prevention, sound insulation and thermal insulation of buildings.

11. The sales price of gypsum mortar seems to be more expensive, but in engineering applications, the comprehensive cost is not more expensive than traditional plastering materials. For example, the thickness of the plastering layer of gypsum mortar can be less than 3mm, while the thickness of cement mortar needs to be more than 6mm-8mm.

To sum up, the use of gypsum mortar engineering cost can be reduced by 10-15%, and reduce rework, waste, is a high-quality environmental protection product for the development of new technology, economic and social benefits are significant, for a number of national policies to focus on recommended, become the majority of users of the new favorite, the use of cement mortar will inevitably replace the cement mortar.

Comparison of plastering performance of gypsum and cement mortar.

1. Good adhesion, suitable for a variety of substrates.

2. Light weight, good construction operability, and less landing ash.

3. Fast coagulation and hardening, energy-saving construction period.

4. The drying shrinkage rate is small, and it should not be hollowed out and cracked.

5. Excellent fire prevention function, and can adjust indoor humidity.

6. The comprehensive cost is low, surrounded by green, and the energy-saving effect is good.

Mortar has a shorter service life.

Workers need to adjust their construction habits.

4. The drying shrinkage rate is small, and it should not be hollowed out and cracked. 5. Excellent fire prevention function, and can adjust indoor humidity 6, low comprehensive cost, green embrace, good energy-saving effect Mortar use time is short, workers need to adjust construction habits.

Question: Which is better?

Which is better, gypsum plastering or cement plastering mortar.

Which is stronger?

No, the former uses gypsum-based as the cementitious material, and the latter uses cement as the cementitious material. The points of plastering gypsum of Shanghai Cornable Building Energy Saving Technology are: 1. Replace cement mortar and completely solve the common problem of "hollowing and cracking" on the wall; 2. It has the function of thermal insulation and insulation, and can meet the energy-saving design requirements by directly painting the wall; 3. The product is early, strong, fast and hard, suitable for mechanized construction, and improves the operation efficiency by 3-4 times; 4. Class A fireproof materials, humidity control, sound insulation, improve living comfort;

1. Cost-effective.

a. Lightweight plastering gypsum: 1100 yuan ton, construction thickness of 8-10mm, plastering area of 118-147 square meters; material cost per square meter;

Calculation method: one cubic light plastering gypsum mortar, according to the thickness of 8mm, plastering area of 125 square meters, according to the thickness of 10mm, plastering area of 100 square meters, one cubic of lightweight plastering gypsum = tons;

That is: one ton of lightweight plastering gypsum, according to the thickness of 8mm can be plastered area of 118 square meters, according to the thickness of 10mm can be plastered area of 147 square meters.

Traditional cement mortar (ready-mixed finished product) :**330 yuan ton, construction thickness 15-20mm, plastering area square meters; material cost per square meter;

Calculation method: one cubic cement mortar, calculated according to the thickness of 15mm = 67 square meters, calculated according to the thickness of 20mm = 50 square meters, one cubic cement mortar is about equal to tons;

That is: one ton of cement mortar, according to the thickness of 15mm can be plastered area of 35 square meters, according to the thickness of 20mm can be plastered area is equal to about 26 square meters.

Note: The above values are theoretical values

b. The amount of traditional cement mortar is 3-4 times that of lightweight plastering gypsum;

Equal: The cost of water and electricity is 3-4 times higher than that of lightweight plastering gypsum used in the project. Take water consumption as an example: one ton of material is 65% to water, calculated according to 20 square plastering area; The amount of light bottom plastering gypsum (plastering thickness 10mm) is 2000 tons; The water consumption is about 1,300 tons; The amount of traditional cement mortar (plastering thickness 25mm) is 6000 tons; The water consumption is about:

3900 tons;

Calculated according to the industrial water yuan ton of Changsha City; 1300 tons = 3081 yuan, 3900 tons = 9243 yuan, can save more than 6162 yuan, plus electricity costs, at least tens of thousands of yuan.

Remarks: The traditional cement mortar needs a lot of water for curing in the later stage, and the lightweight plastering gypsum does not need water supply for maintenance

1. Gypsum plastering mortar is energy-saving, pollution-free, green and environmentally friendly materials, which is technically mature, economically feasible, and in line with the national industrial development direction;

2. Stucco is a kind of dry mix prepared by the factory, compared with the traditional cement mortar and mixed mortar, it has the characteristics of good water retention, light weight and high strength, small shrinkage, small thermal conductivity, etc., which can reduce labor intensity, shorten the construction period, and has a breathing function, and the fire prevention function is expected to be the initial installation effect. It has strong adhesion to cast-in-place concrete and other new wall materials, and does not produce common quality problems such as hollowing and cracking of the stucco layer;

3. The production process of gypsum plastering mortar is simple, easy to realize mechanized and automated production, and has a wide range of use, with good social and economic benefits.

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.

Wall plastering can be either cement mortar or mixed mortar. Mainly selected according to the requirements of use: cement mortar or mixed mortar.

Cement mortar, which is made of cement, fine aggregate and water, can be made into a mortar with higher strength than mixed mortar. In construction projects, cement mortar is used for many purposes, such as foundations, wall masonry, and indoor and outdoor plastering.

1. First of all, before we enter the Songyuan only plastering, we should treat the base layer a thousand cleans, and the smooth surface should be cultivated and watered. And in the process of plastering, it is necessary to take layered treatment, each layer of plastering can not be too thick, and strictly control the interval time, and carry out irrigation and maintenance in time after wiping to prevent hollowing, cracking and other phenomena. 2. Secondly, in the process of installing the window frame, the elevation must be unified, and the size is standard, and the amount of plastering should be reserved around the frame to prevent the plastering from eating the mouth.

3. In the process of plastering, prevent the joint from being placed on the large surface, usually in the lattice seam or in an inconspicuous place to avoid uneven jointing. 4. Before plastering, it is necessary to chisel and water the surface layer of concrete, and then brush 1:1 cement mortar.

Kiss cement and lime plastering wall good 1, powder wall can not use mortar king, powder wall when adding mortar king, will destroy the strength of cement, affect the structure of the wall, resulting in the plastering layer and the base bond is not strong, so that the wall is easy to sand cracking, serious may also corrode the steel bar. 2. Especially the exterior wall, which has been exposed to wind and sun for a long time, if the mortar king is used, the weathering of the paint will be more serious. When the interior wall is tiled in the later stage, it is easy to hollow and fall off, which will cause great trouble to the decoration.

Can you use mortar king to build walls.

It's good to build walls without mortar. It is expressly forbidden to use the mortar king to mix the mortar in the construction of the construction project, and the penetration of the mortar king in the mortar can make the mortar soft and easy to operate, but it will reduce the strength of the cement mortar.
