How to calculate how much cement and sand to buy when decorating

Half of the cement and sand is about 1:3.

If you count the sand, you will calculate the cubic meters according to the number of square meters * thickness.

Lack of experience, to put it simply: sand is divided into medium and fine sand, medium sand floor tiles, fine sand plastering, wall masonry, wall tiles, about half in a home decoration. 1.

Coarse sand: the ground area is multiplied by the height of the pad to know the amount (cube) required, such as the original bathroom, balcony is a few centimeters lower than the living room, the calculated value is about 3cm, my situation is that there is a circle of 6 10cm around the original bathroom and the living room is the same height, in order to finally the living room is higher than the bathroom The highest cushion height. The corresponding amount of cement is about 2 of the volume ratio

1. The density of sand is said in the book. The amount of cement used in this 2:1 is very large, and the amount of cement contracted to the masons is very small, and the reason is understandable.

If it ends up with composite panels, the amount of cement is less. 2. Fine sand: the construction area of wall bricks is multiplied by 1cm, the wall is 1cm of brick joints, 3cm of plastering, and the amount of wall and plastering in the decoration is very small.

The amount of cement is also 2:1, and the amount of cement used for wall building and plastering is very small. The above amount is basically the same, each place to buy sand pricing method is not the same, the hometown has to pay, or to a tractor, where I now live in the big agricultural car (said to be 3 square) Wuling micro car (the boss also said I don't know how much), inquire about the number of a car, needless to say is not accurate, you calculate the amount plus two square numbers are basically a bit redundant.

Cement is a package, 1t20 bags.

Summary. Hello dear "Generally, the ratio of mortar used for floor tiles is 1:2 or 1:

3。A bag of cement is about 3 to 4 square meters, and 25 kilograms of cement are needed per square meter according to 4 square meters (a bag of cement is 25 kilograms that is 100 kilograms), and 50-75 kilograms of sand are needed.

Thank you. Please give it a thumbs up.

This is a detailed method Oh pro: 1. Professional algorithm: Take the 25 square meter courtyard wall as an example:

Check the "project quota" can be seen that the plastering layer is calculated according to the thickness: 1The amount of cement is added for every 5mm increase in thickness, and the same is true for the decrease.

2.The amount of sand is added for every 5mm increase in thickness, and the same is true for reduction. In this way, you can know that your 25 square meters of courtyard wall needs to be plastered on both sides inside and outside a total of 50 square meters, calculated according to the thickness of the plastering

1.The amount of cement required is 11 bales of cement. 2.

The amount of sand required is more than 2 tons of sand. Then, the 25-square-meter wall is considered to be made of red bricks (standard bricks), with specifications of 240 115 53, that is, its volume is mortar with a ratio of 1:3 (because it is a courtyard wall, the strength requirements are slightly higher).

2.The mortar content is (the amount of cement mortar thickness per square meter, that is: 240 walls, a total of 6 cubic bricks, 4000 red bricks.

From (25 6 4000 we can see that 3200 bricks are actually needed, or we can use 128 25 = 3200 to get this value. 128 square meters is the empirical value, like many construction masters are directly calculated with this value. 1.

Therefore, the amount of mortar cement is 401kg m3, which is 13 bags. 3.The amount of sand is 1593kg m3, which is also tons.

If you build 120 walls, a total of 3 cubic bricks, you need 2000 red bricks. 1.The amount of mortar cement is 401kg m3, which is 7 bags.

3.The amount of sand is 1593kg m3, and one ton is enough.

Normally, a pack of cement can pave two square floor tiles; The wall tiles can be paved with three square meters per package of cement; The ratio of cement to sand is 1:2.

If the house is 70 square meters, it depends on the area of the wall tiles. In general, a 70-square-meter house requires 1 ton of cement, and the amount of sand is twice that of cement.

Calculation method: 1. The ratio of cement to sand is 1:

2. Pave bricks and wall tiles of 98 square meters according to the staircase (area square), with pure cement with a thickness of 15mm, about cement (square, without fine sand.

square meters of floor tiles and 100 square meters of geothermal layer with 4cm thick 1: cement sand, cement (19 + 100) * square is required; Requires sand (19+100)* square.

Therefore, about 3 square meters of cement are needed, which is 75 bags per bag and 4 cubic meters of sand.

Generally, it is estimated by the decoration master, and the ratio of cement and sand to the wall and floor tiles is 1:3.

Calculation formula: cement volume (m) wall and floor tile area ( ) pavement thickness (m) 4, sand volume (m) wall and floor tile area ( ) times pavement thickness (m) 4 times 3

For example, a 100-square-meter house, 170 bags of sand, and 40 bags of cement.

Cement and sand are one of the indispensable raw materials for us to renovate a new house, which is related to the overall structural quality of the house. Therefore, it is not allowed to be sloppy in purchase or construction. So how to calculate the decoration sand cement?

Normally, a pack of cement can lay two square floor tiles and three square wall tiles. The ratio of cement to sand is 1:2. If the home area is 70 square meters, you need 1 ton of cement and 2 tons of sand.

What are the tips for picking sand:

1. Look at the particle size.

Sand can generally be divided into four types: extra-fine sand, fine sand, medium sand and coarse sand. For home decoration, it is recommended to choose medium sand, which has a better effect, because the cement mortar blended by coarse sand has high strength. However, too much strength can also lead to cracks in the ground.

On the contrary, the adsorption capacity of sand and sand that is too fine is not strong, and it cannot produce large friction and cause poor bonding.

2. Look at impurities.

Sand is mainly used in the sea, rivers and mountains, and it is best to choose river sand for home improvement. Because although the sea sand is clean, it has high salinity, which is easy to cause serious corrosion to buildings; Although mountain sand and cement have a good effect, the composition is complex; The river sand is moderately coarse and has few impurities.

3. Check the sample.

When purchasing, you can grab a handful of sand with your hands and hold it tightly, then put the sand back in the bag, and then shake off the remaining sand on your hands, if there is still sand left on your hands, it means that the sand can be used, but if the residue is soil, such sand can not be used. Because sand with too high soil content will not only affect the cohesiveness of the cement, but also weaken the hardness of the cement.

5. Purchasing also needs to be done within one's means.

Whether it is natural sand or river sand, you need to screen it once before you can use it after you buy it. However, there are also screened sand on the market, which is higher, so consumers choose according to their actual situation.

Summary: The above is the relevant content of how to calculate the decoration sand cement and what skills to choose sand for you. I hope to bring help to friends in need, if you need to know more about related knowledge in the future, welcome to pay attention to Qeeka Home.

First calculate the area of wall tiles and floor tiles you want to paste, calculate, if there will be a certain amount of labor freight is not cost-effective, you can use the first material appropriately less, which should be considered according to the actual situation, cement 700kg, as long as the material is in two times is very good, other dosages are to be considered according to the actual practice, sand 9kg. Other dosages consider one cubic (1500kg) of sand. , floor tiles according to a square cement 25kg.

How to calculate home improvement, sand and cement.

Dear, hello, I am happy to answer for you, how to calculate the amount of sand for home improvement, sand and cement. According to the ratio required for construction, the capacity of the required sand can be obtained, and thus the approximate weight of the sand. Take 10 square meters as an example:

The quantity of cement mortar 10 average thickness) = cubic meters. Sand dosage: weight of sand per cubic meter) = ykg.

Calculate the amount of cement used. Take ordinary slag Portland cement as an example, its specific gravity is . The net weight of each bag of cement is 50 kg, which is about cubic meter bags.

Approximate algorithm. Take 10 square meters as an example: quantity of cement mortar 10 * average thickness) = cubic meters.

The amount of sand used per cubic meter of mortar ( ) = 225kg. Cement dosage 225 Cement and sand mix ratio according to Consider, this strength is enough) You can calculate it yourself according to the actual area.
