How much cement does one cubic cement slurry need How much cement do you need for 1 cubic cement slu

One cubic cement slurry, water-cement ratio, water intake: cement: 1, the specific gravity of cement is about 3 tons per cubic meter.

The specific gravity of the cement slurry is calculated to be about. One cubic meter is equal to 1000l. Therefore, 1 cubic meter of cement slurry weighs about tons.

Backwards, tons of cement slurry need about tons of cement, take tons.

450 kg of cement.

One cubic of mortar is to add the corresponding cement and sand, the ratio is generally 1:4, that is to say, one cubic of mortar is at least to add 1350 kg of sand and 450 kg of cement.

If the quality of cement is relatively stable, it is often necessary to add less when adding cement, so as to have a very good fixing effect, and the weight of cement and sand that needs to be added by different types of mortar must be different, which is also to be seen in combination with the actual situation.

Precautions for the use of cement slurry.

Cannot be mixed. There are differences in the quality and performance of different varieties and strength grades of cement, which should be stacked separately and used separately, including cement of the same variety but different manufacturers shall not be mixed.

Reasonable selection of cement varieties and strength grades. According to the construction site and engineering technical requirements, the cement variety and strength grade should be reasonably selected, so as to avoid the improper selection of cement, resulting in substandard project quality or increased cost.

During cement construction, it is necessary to strictly control the quality of sand, stone, water and other materials used, try to choose sand and gravel with less mud content, and the water used shall not contain organic substances (sugar, fertilizer, washing supplies, etc.), and when preparing concrete in summer or winter, it is necessary to pay attention to controlling the temperature of sand and water to avoid concrete setting time too fast or too slow.

1. If 1:1 is the volume ratio.

The density of water is 1 gram cubic centimeter, the density of cement is gram cubic centimeter, and the weight of cement is about 3 times the weight of water under the same volume. 500 kg of cubic water, about 1550 kg of cubic cement.

Therefore, 1550kg of cement and 500kg of water are needed.

2. If 1:1 is the mass ratio.

Cement and water each need about 750kg.

It can be preliminarily estimated using the volumetric method:

Cement weight x kg, density.

x/x=759kg

Because in actual use, the cement slurry may contain a certain amount of bubbles, so the actual amount of cement in each square cement slurry may be lower.

Concrete is the most commonly used building ruler material in civil engineering, it is made of cement, sand, stone in proportion to mix, we often need to use concrete to build houses, so how much cement will we use to make a cubic of concrete? Next, I will briefly introduce it to you.

1. How much cement is used for 1 cubic concrete.

1. According to the experts of Qeeka Home, the cement used in 1 cubic concrete is not fixed, because the concrete ratio of different grades is different, and the amount of cement used is also different.

For example, we use cement with a strength grade of C20, and the cement required per cubic meter is 350kg, 185kg of water, 690kg of sand, and 1160kg of stone. The concrete strength grade is C30, and the cement required per cubic meter is 450kg, water is 183kg, sand is 600kg, and stone is 1192kg.

2. The strength of the cement grades we use is different, even if the concrete strength grade is the same, the amount of cement used will be different. For example, if the strength of concrete is C25 and 325 cement is used, the cement required per cubic meter is 400kg, water is 185kg, sand is 650kg, and stone is 1180kg; If 425 cement is used, the amount of cement required per cubic meter is 340kg, water is 185kg, sand is 800kg, and stone is 1045kg.

3. Concrete is a commonly used building material, which is made of cement, sand, stone and water mixed and mixed in a certain proportion. According to the strength of concrete, it can be divided into 14 levels, such as C15, C20, C25, C35, C50, C60, etc., and in general, C20 and C25 grade concrete are used for ordinary reinforced concrete structures such as stairs and beams and columns; C15 grade concrete is used in floors, cushions and structures with little stress, etc. The strength of concrete used in rural construction is mostly between C15-C30.

1. According to the different strength grades of 1 cubic concrete, all cement strengths are different, and the amount of cement required is also different.

1. Legislation cement slurry requires about tons of cement.

1 cubic cement slurry, water-cement ratio, water intake: cement: 1, the specific gravity of cement is about 3 tons per cubic meter.

The specific gravity of the cement slurry is calculated to be about. One cubic meter is equal to 1000l. Therefore, 1 cubic meter of cement slurry weighs about tons. Backwards, tons of cement slurry need about tons of cement.

Calculation method: cement density, water density 1, cement slurry volume = water + cement, cement slurry weight = water + cement weight. Water-cement ratio = water weight cement weight. Cement slurry density = cement slurry weight Cement slurry volume.

Composition of cement slurry:

Cement slurry refers to a mixture made of cementing materials (organic qiyan, inorganic or organic-inorganic composites), granular aggregates, water, chemical admixtures and mineral admixtures that need to be added in appropriate proportions, or composite materials with a stacking structure are formed after socks are back hardened (usually cementitious materials, water, fine aggregates, and coarse aggregates).

Precautions for cement slurry construction:

1. The water-cement ratio should not be greater than that;

2. When grouting through the temporary casing, the placement of the steel bar should be completed before the temporary casing is pulled out, and the grouting pressure should be applied every 2 meters during the casing pulling process;

3. When the pipe fittings are used as load-bearing members, grouting can be carried out through the bottom;

4. When using flower tube grouting, the full length of the grouting can be carried out by the flower tube for many times, and also can be carried out by the flower tube and the special valve for segmented grouting or through the staggered post-grouting pipe for step-by-step grouting of each other;

5. Secondary and multiple grouting can only be carried out after the cement slurry injected by the above method is solidified. When the design specified grouting pressure can not be applied, should wait until the specified grouting pressure can be applied;

6. At the end of the grouting process, the grouting pipe should be filled with cement slurry and maintain the grouting pressure for a certain time;

7. When using gravel or fine stone filling and grouting process, the filler should be cleaned, and the input should not be less than the multiple of the volume of the calculated pile hole, and the grouting pipe should be used to inject water to clean the hole at the same time. <>

1 cubic concrete is offered with 480 kg of cement, 720 kg of sand and 1200 kg of stone.

The mass of 1 cubic meter of concrete is about 2400 kg. 1 cubic meter of concrete is calculated as 2400 kg:

Cement mass = 2400 2 (2 + 3 + 5) = 480 (kg);

sand mass = 2400 3 (2 + 3 + 5) = 720 (kg);

Stone mass = 2400 5 (2+3+5) = 1200 (kg).

A cube of concrete is about.

Different concrete requires different amounts of cement, for example: 1 concrete next to the trace C20, 300 kg of cement is required for production. 180 kg of water, 690 kg of sieves and 1260 kg of stones are required.

If you use C25 concrete, you need about 372 kg of cement, 576 kg of sand, and 1282 kg of stone.

How to maintain the concrete floor.

1. The construction party should draw up a construction plan for a large area of concrete, adopt the method of temperature control, and measure the temperature of concrete, and during the curing period, the concrete protection method needs to be adjusted according to the temperature measurement.

2. There are different requirements for concrete pouring, and the construction party should contact the on-site technician in time, and the laboratory technicians will adjust the concrete construction ratio. When the concrete slump cannot meet the on-site pouring, it should be adjusted by the on-site technician.

3. Before pouring concrete, the pump truck should use the correct method to cool down the construction site and steel bars, and the pump pipe can be covered with wet sacks, or it can be cooled by spraying cold water, and the insulation method should be used for the formwork.

4. If it is the first pouring, it should be constructed at night as much as possible, which is conducive to reducing the temperature of concrete into the mold, reducing the pouring time during the day, and using the method of shading during the day to avoid surface exposure.

5. After pouring the concrete to the elevation, the concrete needs to be plastered, and the plastic film can be covered on the surface. In order for the concrete surface to harden, be sure to cover the straw curtain and sprinkle it with water sufficiently, keeping it wet for at least 24 hours. If water is not sprinkled after the cover of the stool is closed, a lot of heat of hydration will occur, causing cracks in the ground.

6. After the concrete is solidified, it should be protected by water storage, and the water should be evenly discharged when storing water to avoid too much difference in the temperature of the concrete surface.

7. When protecting the concrete, we should pay attention to weather changes, avoid the ground being exposed to the sun, heavy rain, and when the temperature changes, the insulation material should be used to keep warm, and we should also pay attention to protecting the ground to avoid cracks.
