How to calculate the amount of cement and sand for laying ceramic tiles

by admin

generally, the mortar ratio for paving floor tiles is 1:2 or 1:3, and a bag of cement can be paved for about 3 to 4 square meters. If calculated according to 4 square meters, 25 kg of cement is required per square meter (25 kg for a bag of cement is 100 kg), then 50-75 kg of sand in the same proportion is required. This is only a theoretical calculation, which will be more in practical use. Because the ground is uneven, there will be loss

for example, if the subsidy area is 20 square meters and the paving thickness is calculated according to 4 cm, the cement consumption at this time is 20 square meters × zero point zero four × 0.25 ÷ 0.04 = 5 bags of cement; The amount of yellow sand is equal to 20 square meters multiplied by 0.04 multiplied by 0.75, and the final result is about 0.6 cubic meters of sand

extended data:


1. Ceramic tiles should be fully soaked. Ceramic tiles should be fully soaked before paving. This is mainly to make the pores in the ceramic tiles absorb water. In this way, hollowing and falling are not easy to occur during paving. If the ceramic tiles are not soaked and pasted directly on the wall, it is likely that the ceramic tiles will directly absorb the water in the cement

2. Choose high-quality cement sand tiles. If you want to have good paving quality, you must choose high-quality cement sand, so that the tiles will stick tightly; The key point of selecting cement is to check whether it has passed the shelf life. If it has passed the shelf life, it’s best not to buy it; The best choice of sand is river sand. River sand contains more water, and the pasting effect will be better

3. The position of the first brick must be selected. The position of the first brick determines the position of the ceramic tile in the whole wall, so the position of the first ceramic tile must be selected. If the position of the first ceramic tile is wrong, the ceramic tile of the whole wall will be skewed

the first: approximate algorithm: take 10 square meters as an example:
quantity of cement mortar 10 * 0.015 (average thickness) = 0.15 cubic meters, quantity of sand 0.15 * 1500kg (quantity of sand per cubic meter) = 225kg
quantity of cement 225 /2.5 = 90kg (the mixing ratio of cement and sand is 1:2.5, which is enough strength). You can calculate it according to the actual area
the second: super professional algorithm: take a 25 square meter courtyard wall as an example:
according to the project quota, the plastering layer is calculated according to the thickness of 2.5cm:
the cement dosage is 10.6kg/m2, and 2.12kg/m2 will be added for every 5mm increase in thickness, which is the same as the reduction. For every 5mm increase in thickness, 42.8kg/m2 of sand will be added with 8.56kg/m2, which is the same as the reduction.
it can be seen that your 25 square meter courtyard wall needs 50 square meters of plastering on the inner and outer sides, Calculated according to the plastering thickness of 2.5cm:
the cement demand is 10.6kg/m2 × 50m2 = 530kg, that is, the required amount of 11 bags of cement sand is 42.8kg/m2 × 50m2 = 2140kg, that is, more than 2 tons of sand. First provide you with a data of wall plastering
according to the project quota, the plastering layer is calculated according to the thickness of 2.5cm:
the cement consumption is 10.6kg/m2, and 2.12kg/m2 is added for every 5mm increase in thickness, which is the same as the decrease of 42.8kg/m2. For every 5mm increase in thickness, 8.56kg/m2 is added, which is the same as the decrease of
25 m2 wall, red brick (standard brick) is considered, and the specification is 240 × one hundred and fifteen × 53, i.e. its volume is 0.0015m3. The mortar adopts the ratio of 1:3 (due to the courtyard wall, the strength requirement is slightly higher)
the mortar content is 0.265m3/m3 (dosage per square meter) × Thickness of cement mortar: 10.6 × 0.025 = 0.265) build 240 walls, a total of 6 cubic bricks, 4000 red bricks are required
(25 × 0.24=6 6/0.0015=4000 4000 × 0.8 = 3200), i.e. 3200 bricks are actually needed, or 128 × 25 = 3200 can also get this value. 128 yuan /m2 is the empirical value, which is directly used by old Masons
mortar required: 0.265m3/m3 × 6m3 = 1.59m3
cement consumption 401kg /m3 × 1.59m3 = 637.59kg, that is, the amount of 13 bags of sand is 1593kg /m3 × 1.59m3 = 2532.87kg, that is, 120 walls built with 2.5t. There are 3 cubic bricks in total, and 2000 red bricks are required. Mortar required: 0.265m3/m3 × 3m3 = 0.795m3
cement consumption 401kg /m3 × 0.795m3 = 318.8kg, that is, 7 bags
sand consumption 1593kg /m3 × 0.795m3 = 1266.44kg, 1.5T is enough
note: the above are theoretical values. For example, the gap in the wall should be considered in the actual decoration process. If the theoretical value of 160 bricks required for 1m2 wall building is 160, only 128 bricks are required in practice, i.e. 164 bricks × 0.78 = 128 blocks (24 walls)
the third: the simple algorithm is as follows:
just make it with ordinary mortar, the water cement ratio is about 0.6, and the sand and cement can be made as 1:1, or less
or one bag of cement and two bags of sand can be plastered with 4 square meters.

 1. Standard calculation: according to 50 kg of cement in a bag, a bag of cement can lay 2 ㎡ floor tiles, that is, 25 kg of cement in 1 ㎡, and 75 kg of yellow sand is required according to the ratio of 1:3. Therefore, 100 kg of sand cement is required to paste 1 ㎡ floor tile

 2. According to the thickness of floor tiles, the amount of cement and sand required is also different. If calculated according to the thickness of 30cm, the cement required for one square meter is about 11kg and the sand required is about 0.3m3. The specific calculation formula is as follows: sand consumption = thickness * paving area, and the cement consumption is generally one third of that of sand

 3. Sometimes the materials used between the two also depend on the thickness of your paving bricks and the size of your floor tiles. For example, generally, 8-10 bags of cement sand are required for a toilet wall brick and face brick, and about 15-20 bags for small packaging

 how much cement and sand is used for one square meter of floor tiles 

 calculation of cement and sand consumption during Tiling: 

 calculation of cement consumption: Area × Paving thickness × 0.25 /0.04 = number of bags of cement 

 calculation of sand consumption: Area × Paving thickness × 0.75 = cubic number of sand 

 calculation formula for cement sand consumption of 1 square floor tile: 

 cement dosage: paving thickness × 0.25 /0.04 = number of bags of cement 

 sand dosage: paving thickness × 0.75 = cubic number of sand 

 assuming that the thickness of the floor tile is 10 cm and the paving area is 100 square meters, the amount of sand used is: 0.1x100 = 10 square meters, that is, 10 square meters of sand is required to finish the 100 square meters of brick, and the amount of cement is generally 1 /3 of the amount of sand, that is, 5 tons of cement, which is almost 100 bags of cement

 the above is about the amount of cement and sand used for one square meter of floor tile and the calculation formula of cement and sand consumption for one square meter of floor tile. The amount of cement and sand can be calculated according to the above formula. When paving floor tiles, it is not only nece
ssary to grasp the precautions of floor tile paving, but also important to select a suitable floor tile

English name

English name of cement

noun explanation

powdery hydraulic inorganic cementitious cement Material Science. It can harden in air or water and firmly bond sand, stone and other materials together. Cement is an important building material. Mortar or concrete made of cement is strong and durable. It is widely used in civil construction, water conservancy, national defense and other projects

the word cement is developed from the Latin caementum and means gravel and rubble. The history of cement can be traced back to the mixture of lime and volcanic ash used by the ancient Romans in construction projects. In 1796, the Englishman J. Parker fired a brown cement called Roman cement or natural cement from marl. In 1824, the Englishman J. asPutin burned limestone and clay into cement. The hardened color was similar to the stone used for construction in Portland, England. He was named Portland cement and obtained a patent. At the beginning of the 20th century, with the improvement of people’s living standards, the requirements for construction projects have increased day by day. While constantly improving Portland cement, a batch of cement suitable for special construction projects, such as high alumina cement and special cement, has been successfully developed. The variety of cement has developed to more than 100

the production process of cement takes limestone and clay as the main raw materials, which are crushed, proportioned and ground into raw materials, fed into the cement kiln to calcine the mature materials, and added with an appropriate amount of gypsum (sometimes mixed materials or admixtures). According to the use and performance, it is divided into three categories: ① general cement. It is used in general civil engineering and construction projects, such as Portland cement (the general name of cement with calcium silicate as the main mineral, which is collectively referred to as Portland cement internationally, including ordinary portland cement, slag, pozzolanic ash, fly ash, mixed Portland cement, etc.). ② Special cement. It is used in some special projects, such as oil well cement, molding sand cement, etc. ③ Special cement. It is used in projects with special requirements for some properties of concrete, such as fast hardening cement, hydraulic cement, sulfate resistant cement, expansion cement, self stressing cement, etc. The performance of cement must meet the fineness, setting time, stability, strength, specific gravity, hydration heat, impermeability, frost resistance, expansion and shrinkage, heat resistance, corrosion resistance and other indicators specified in national standards

classification of cement

cement is divided into:

1. General cement: Cement commonly used in general civil and construction engineering. General purpose cement mainly refers to the six categories of cement specified in gb175-1999, gb1344-1999 and gb12958-1999, namely Portland cement, ordinary portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement and composite Portland cement

2. Special purpose cement: special purpose cement. Such as class G oil well cement and road Portland cement

3. Characteristic cement: a kind of cement with outstanding performance. Such as: fast hardening portland cement, low heat slag Portland cement and expanded sulphoaluminate cement

cement is divided into:

1. Portland cement, commonly known as Portland cement abroad

2. Aluminate cement

3. Sulphoaluminate cement

4. Ferroaluminate cement

5. Fluoroaluminate cement<
> the main components are cement, water and other potentially active materials

the main technical characteristics of cement indicated in the naming of cement are divided into:

(1) fast hardening: it is divided into fast hardening and ultra fast hardening

(2) hydration heat: divided into medium heat and low heat

(3) sulfate resistance: divided into medium sulfate resistance and high sulfate resistance

(4) expansibility: divided into expansion and self stress

(5) high temperature resistance: the high temperature resistance of aluminate cement is graded by the content of alumina in the cement. 4、 General principle of cement naming:

the naming of cement is based on water according to different categories
