Can you make cement cylinders with cement at about minus two degrees in winter?

Obviously not, and at the same time impossible.

The so-called: work to do a good job! There is a lot of time in the year when you can make cement tanks, but you are under the condensation point of water!

Although the cement generates heat after adding water, it can remain non-freezing at minus 2 degrees, but the solidification characteristics are changed, and its strength is greatly reduced.

If you really want to make cement tanks, you can do it indoors, at least the room temperature can be kept above freezing, so that it will not affect the solidification and hydration of the cement. When making it, use 6 circles to weave the skeleton, try to be as dense as possible, and pour it with bean stone concrete.

In winter, it is about minus two degrees, and it cannot be used to make cement cylinders. Because at this time, the water will freeze, which seriously affects the strength of the cement after drying.

No, the temperature cannot be reached, the concrete solidifies slowly, and it will cause water-cement separation, the formation of crispy crystals on the surface, and the formation of ice crystals inside will affect the strength.

If there is a heat preservation condition after doing it, of course it can be done, otherwise, it can't be done. If the temperature is too low, it will freeze and spoil, which can not be used and waste materials and costs, and the gains outweigh the losses.

Normal sub-zero has an impact on the cement ash number, and the quality of the products or buildings made is unqualified.

You can do it at noon, but if the temperature is below zero the day before yesterday and there is no sun, it is not recommended.

No, you cannot.

According to the winter construction requirements, when the average outdoor daily temperature is stable below 5 °C for 5 consecutive days, it is not suitable for construction. Because the temperature drops in winter, the temperature in many areas is below 0 °C (that is, negative temperature), the moisture contained in soil, concrete, mortar, etc. freezes, and building materials are easy to brittle, which brings many difficulties to building construction.

There are two methods of plastering in winter: hot work and cold work:

1. Hot practice. A method to solidify the plastering mortar under normal temperature conditions by increasing the indoor temperature during operation. The ambient temperature can be increased by heating the oven or steam pipe, or by baking with far-infrared rays.

2. Cold method. Plastering is carried out with mortar mixed with antifreeze without heating and insulation. This method is often used for exterior wall plastering. However, it cannot be used in projects that are close to the power supply, are often in a wet state, and have high appearance requirements.

No matter what method is taken, the winter plastering must be carried out when the building has settled and stabilized, the masonry strength has reached more than 20% of the design strength, and the concrete strength has reached more than 40%, so as to avoid cracking and peeling of the plastering layer in the future.

Yes, my family is powdered at this temperature.

It is better not to, if you have to, add antifreeze. But now the weather in the north is absolutely not.

Put salt in the cement and it won't freeze.

Then you are in Aidu, at night in Sandu, which can be worn, the cement that can be smeared, and it can't rain in the future, because if the temperature is relatively low, he will dry more slowly. You have to be red on the last five, don't climb in the afternoon, or you will be motivated.

Can I come to minus 2 degrees during the day and minus 3 degrees at night? I think this problem can still be made of cement ash.

Generally speaking, it is easy to freeze below zero, and the cement ash that is too thin will be frozen and cracked, or frozen off, and it will not work.

In this case, you generally do not touch it, because this situation will freeze, and the effect on the cost of plastering cement is not very good.

You can also wipe this cement ash at minus 3 degrees, but it will be more tiring.

Yes, pro, it would be better if it was sunny during the day, and this temperature was fine.

Now there is no 325 and 425 cement, only or cement, generally use cement, rarely used, but generally build your own house, use cement, it is also possible,

How to plaster cement at minus 2 degrees during the day and minus 3 degrees at night.

Around zero degrees will be unfavorable to cement hardening, but it is not absolute, it should be noted that it is necessary to carry out anti-freezing and warmth, and it should be possible to build a house in a particularly cold area.

The powder exterior wall is made of the ground at any time for a few days with relatively high temperature weather, and there are days on it. The interior walls will not be affected.

Stop working below zero as much as possible. When the temperature is above minus 10 degrees, cement antifreeze is added to the concrete, and the cement quality is added according to different temperatures3 8. The temperature is below -10 degrees Celsius, so let's stop.

Portland cement production technology represents that in cement production, limestone and clay are the main raw materials, after crushing, the raw materials, ground into raw materials, and then fed to the cement kiln to calcine the mature materials, and then with an appropriate amount of clinker gypsum (sometimes admixtures or admixtures) to grind fine.

The cement is frozen, to fail, here is the cement that has been used for construction, before the strength is frozen, the strength can not reach the design number. Generally, if you don't take measures at -5 degrees, you will freeze. Frozen cement is powdered.

Unused cement, i.e. dry cement, will not fail.

As long as the cement is stored dry, the time is not too long, even if the low temperature will not fail, but the concrete is afraid of freezing.

There are many kinds of cement, and it seems that it will not fail!

Cement can be used normally, and heating should be taken during construction to ensure that the temperature of mixing, construction and maintenance is higher than 5 degrees above zero to ensure the normal hydration of cement.

Do I need to add antifreeze before I use it?

No. In winter, the temperature is low, and if the working surface such as plastering, scraping mud, and tiling is frozen, there will be quality problems such as hollowing. If you are decorating a rough room, it is best to place an electric heater to increase the indoor temperature.

In winter construction, whether it is wall tiles, floor tiles or gypsum board, it is best to place them for one day before using them after being transported indoors, so that they can reach a certain balance with the indoor temperature and avoid thermal expansion and contraction after construction, and the phenomenon of hollowing and falling off occurs.

It is best to soak the tiles in water before paving, so that they can be more firmly bonded with cement. In winter, the indoor air is dry, the water loss is faster, and the mud can not be scraped too thickly, so it is necessary to wait for the latex paint to dry before brushing, otherwise it is easy to cause cracking.

No.

Exterior tiles that are pasted in winter are prone to problems.

After the Huashang Daily reported that the tiles of Weiye Building fell seriously and the outer wall of the building became a mosaic, on the 12th, the person in charge of the property of Weiye Building showed reporters a record of their daily monitoring of the external wall from 2013 to the present.

The building was built in 1998, and since 2013, the exterior tiles have been falling off. In the past three years, it has been prone to problems when there is bad weather from April to July. A property officer of the building said.

According to the reporter's understanding, due to the lack of overhaul of Weiye Building, the restoration work has been difficult to carry out, and staff can only be arranged to monitor the situation of external wall tiles.

Tiles that are pasted in winter are prone to problems. Yesterday, a worker repairing the exterior wall tiles in Rong Qiao Town said, "The cement sets slowly in winter, and we have repaired the exterior wall tiles of many real estate buildings, and almost all the tiles that fall off are pasted in winter." ”

About minus 2 degrees can not be painted cement wall tiles, because the solidification of cement mortar requires a certain period of time, if the temperature is lower than zero, it will affect the firmness of the bonding of tiles.

Under normal circumstances, the indoor temperature of ceramic tile paving is required to be above 5 °, and if the temperature is too low, the cement mortar of the ceramic tile has a long solidification cycle, which affects the firmness of the ceramic tile paste.

Yes, it's also indoors, and it's definitely fine indoors if it's -2 outdoor. The solidification time is a little longer.
