What is the mix ratio of C25 concrete

C25 pebble concrete: cement (: sand: stone: water =

The amount of cement per cubic meter is 352 kg, 608 kg of sand, 1,250 kg of gravel and 190 kg of water. Collapse 50-70mm

C25 crushed stone concrete: cement (: sand: gravel: water =:

The amount of cement per cubic meter is 336 kg, 706 kg of sand, 1,153 kg of gravel, and 205 kg of water. Collapse 50-70mm

According to the ratio notice of the construction engineering quality inspection center for calculation, if there is no construction engineering quality inspection center of the ratio notice, you can refer to the quota behind the ratio table for construction, generally cement: yellow sand: gravel: water 414kg: ::

The mix ratio is ever-changing, and different raw materials must be different. For the same raw material, the water-cement ratio determines the strength.

Summary. The mix ratio of C25 concrete is generally: cement: sand: gravel = 1:3:6.

The mix ratio of C25 concrete is generally: cement: sand: gravel = 1:3:6.

Can you elaborate on that a little bit more?

The mix ratio of C25 concrete is 1:2:4, that is, 1 part cement:

2 parts of sand: 4 parts of crushed stone, of which the amount of cement is 360 kg cubic meters, the amount of sand is 720 kg cubic meters, and the difference in the amount of crushed stone is 1440 kg cubic meters. The ratio of cement and sand can be adjusted, but the ratio of cement and gravel cannot be adjusted and must be kept at 1:

4。In addition, C25 concrete also needs to add a certain amount of cement doped section to improve the strength and crack resistance of the concrete.

The general mix ratio of C25 concrete is cement: sand: stone:

Water = 1::: That is, one side of C25 concrete, you need 370kg of cement, 582kg of sand, 1287kg of crushed stone, and 175kg of water. The so-called concrete construction mix ratio refers to the proportional relationship between the constituent materials in the concrete.

Concrete mix design is a very important work in concrete engineering, which directly affects the smooth construction of concrete, the quality of concrete engineering and the cost of concrete engineering. Hope mine is helpful to you. Have a great day.

What is the general mix ratio of C25 concrete?

Sand:pebble:water = 1:::

That is to say, one side of C25 concrete needs 370kg of cement, 582kg of sand, 1287kg of crushed stone, and 175kg of water.

What about C2O. C30.

One side of C30 concrete, the mix ratio is cement: sand: stone: water = 1::: that is to say, one side of C30 concrete, need 400kg of cement, 512kg of sand, 1252kg of gravel, 175kg of water.

One side of C20 concrete, the mix ratio is cement: sand: stone: water = 1::: that is to say, one side of C20 concrete, need 343kg of cement, 637kg of sand, 1301kg of gravel, 175kg of water.

1. The mix ratio of C25 concrete is.

The amount of concrete cement in one cubic meter is 411kg, sand cube, stone cube, and water cube.

2. The C30 concrete mix ratio is.

One cubic C30 concrete: water: 175kg; Cement: 461kg; Sand: 512kg; Stones: 1252kg.

3. A cubic C35 concrete mix ratio: cement tons, sand cubic meters, stone cubic meters, and sand account for about 91% of the concrete volume.

Principles of concrete mix design:

1. The workability of the concrete mixture can meet the needs of construction;

2. The strength of concrete can meet the requirements of the design;

3. Concrete should have good durability;

4. When meeting the above requirements, minimize costs and increase benefits.

Each cubic meter of C25 strength grade of concrete needs about 325 cement 470 kg, medium sand 682 kg, stone 1176 kg, water 210 kg, the ratio is--- 325 cement genus: medium sand:

pebble=1::; or 425 386 kg of cement, 775 kg of medium sand, 1175 kg of gravel, and 210 kg of water.

Ordinary concrete is divided into fourteen grades, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80. For example, a concrete with a strength grade of C30 is 30MPa FCU, K<35MPa.

The main factors affecting the strength grade of concrete are cement grade and water-cement ratio, aggregate, age, curing number, temperature and humidity.
