How many stones, sand, cement, and water are needed for one side of concrete?

Because of the concrete strength grade.

Different will have different mix ratios, so the amount of cement, sand, and mortar is also different.

For example: concrete: cement 480 kg, sand 650 kg, crushed stone 1154 kg.

Underwater concrete: cement 383kg, sand 789kg, crushed stone 1046kg.

Pumped concrete: cement 370kg, sand 719kg, crushed stone 1077kg.

Ordinary concrete: cement 353kg, sand 691kg, crushed stone 1128kg.

Concrete: cement 395kg, sand 661kg, gravel 1174kg.

Pumped concrete: cement 426kg, sand 718kg, crushed stone 1076kg.

According to the Code for the Design of Concrete Structures

The concrete strength grade of plain concrete structure should not be lower than C15, reinforced concrete structure.

The concrete strength grade should not be lower than C20. The strength grade of concrete when using steel bars with a strength grade of 400MPa and above.

It should not be lower than C25. For reinforced concrete members under repeated loads, the concrete strength class should not be lower than C30.

Generally speaking, one cubic meter of concrete requires about 5-8 bales of cement, which is about 2350kg 2400kg. It depends on many factors, such as use, location, strength requirements, gravel particle size, cement grade.

Wait a minute. What is the weight of a piece of concrete? Sand, cement and gravel? Generally, the weight of one cubic meter of concrete is 2350kg-2400kg. Concrete is concrete.

To sum up, stones and sand in a concrete.

The amount should be calculated in advance. One cubic meter of concrete requires the preparation of about 700 kg of sand, about 1240 kg of stone. In addition, add cement, about more than 300 catties. When adding water, the water content.

About 180 200 kg.

Concrete is divided into strength grades, the weight of concrete in different strength grades is different, and the strength grade of concrete refers to the compressive strength of concrete. In the construction of rural self-built houses, C15, C20, C25 and C30 are mainly used. Cement is 325 cement.

1.One side C15 concrete Cement: sand: stone: water = 1::: One side C15 concrete, 284kg of cement, 702kg of sand, 1351kg of gravel, 172kg of water.

2.One side C20 concrete Cement: sand: stone: water = 1::: One side C20 concrete, 343kg of cement, 637kg of sand, 1301kg of crushed stone, 175kg of water are needed.

3.C25 concrete on one side Cement: sand: stone: water = 1::: C25 concrete on one side, 370kg of cement, 582kg of sand, 1287kg of crushed stone, 175kg of water are needed.

4.One side C30 concrete Cement: sand: stone: water = 1::: one side C30 concrete, need cement 400kg, sand 512kg, gravel 1252kg, water 175kg.

It takes 400 kilograms of cement, 512 kilograms of sand, 1250 kilograms of stones, and 175 kilograms of water.

The ratio is about 1:3:3:3. There must be more water, otherwise it will not be able to get along. It's very slimy when the time comes.

C20: water 175kg m3; cement 330kg m3; sand 621kg m3; Stones: 1260kg m3;

C25: water: 175kg m3; Cement: 372kg m3: Sand: 576kg m3: Stone: 1282kg m3;

The density of C30 concrete will vary due to the different mix ratios, if the cement is selected, the cement quality will be reduced, the quality of water will also be reduced, and the amount of sand and gravel will increase a little. Therefore, the density of C30 concrete is closely related to what kind of raw materials are selected.

Technical requirements. 1. For concrete sand with frost resistance, impermeability or other special requirements, its mud content should not be greater than 3%.

2. For concrete sand below C10 and C10, according to the cement number, its mud content can be relaxed as appropriate.

3. For concrete sand with frost resistance, impermeability or other special requirements, the mud content should not be greater than 1%.

4. For concrete sand below C10 and C10, the mud content can be relaxed according to the cement number.

5. For concrete with anti-freezing and impermeability requirements, the mica content in the sand should not be greater than 1%.

Mix ratio: 1:::

If it is 1 cubic meter of C30 concrete, 1 cubic meter of concrete is about equal to a ton. A cubic meter of C30 concrete needs to be packed with cement, cubic meters of yellow sand, cubic meters of stones and cubic meters of water.

One cubic of C30 concrete requires 270 kg of cement, 700 kg of yellow sand, 1,326 kg of gravel and 192 kg of water.

1 cubic meter C30 concrete raw material mass = 270 + 700 + 1326 + 192 = 2488 (kg).

The amount of sand and gravel contained in one side of the concrete can be obtained by the proportional relationship of cement: sand: gravel =, that is, the amount of sand required =, the amount of stone required =

PS: There are many factors that affect this, such as the number of concrete, which is only an approximate proportion.

The following concrete dosage and mix ratio of two different strengths are introduced;

Summary. The amount of stone, sand and cement required for one side of concrete is calculated according to the mix ratio of concrete, and the specific mix ratio depends on the use and strength of the concrete. In general, the commonly used mating ratios are as follows:

1:2:3 (cement:.)

Sand: aggregate, strength grade C15 C20) Cement: sand:

aggregate, strength grade C25 C30) 1:3:4 (cement:

Sand: aggregate, strength grade C30 C35) at 1:2:

For example, the quantity of materials required for one side (i.e. cubic meter) of concrete is calculated as follows: cement: assuming the use of ordinary Portland cement, 50kg per bag, the quantity of cement required is 1 6 cubic meters, that is, bags (1 6 * 1000kg 50kg).

Sand: According to the proportion, 2 times the cement of sand is required, that is, 1 3 cubic meters (2 * 1 6), about tons (1 3 * 2400kg 1000kg). Aggregate (stone):

According to the proportion of mixing, 3 times the aggregate of cement, that is, 1 2 cubic meters (3 * 1 6), about tons (1 2 * 3000kg 1000kg) are required. Water: The amount of water is generally 40% to 60% of the amount of cement, that is, the multiple of the amount of cement.

Taking a 1:2:3 ratio as an example, a multiple of the amount of cement is required, i.e. cubic meters, about 80 100 kilograms of water.

The amount of stones, sand and cement required for one side of the concrete is calculated according to the mix ratio of the concrete, and the specific mix ratio depends on the use and strength of the concrete. Generally speaking, the commonly used mating ratios are as follows: 1:

2:3 (cement:sand:.)

Aggregate, strength grade C15 C20) cement: sand: aggregate, strength grade C25 C30) 1:

3:4 (cement:sand:.)

aggregate, the strength grade is C30 C35) Take the mix ratio of 1:2:3 as an example, calculate the amount of material required for one side (i.e., cubic meter) of concrete as follows:

Cement: Assuming the use of ordinary Portland cement, 50kg per bag, the quantity of cement required is 1 6 cubic meters, that is, bags (1 6 * 1000kg 50kg). Sand:

According to the proportion, 2 times the cement of sand is required, that is, 1 3 cubic meters (2 * 1 6), about 1 3 * 2400kg 1000kg. Aggregate (stone): according to the matching ratio, 3 times the cement aggregate is required, that is, 1 2 cubic meters (3 * 1 6), about tons (1 2 * 3000kg 1000kg).

Water: The amount of water is generally 40% to 60% of the amount of cement, that is, the multiple of the amount of cement. Take 1:

For example, a 2:3 ratio requires a multiple of the amount of cement, i.e. cubic meters, and about 80 100 kilograms of water.
