What is the conventional C10 C15 C20 C25 C30 concrete mix ratio

Conventional C10, C15, C20, C25, C30 concrete mix such as the figure below.

The so-called concrete construction mix ratio refers to the proportional relationship between the constituent materials in the concrete. Adjustment steps: set the laboratory mix ratio as:

Cement: Water: Sand:

Pebble = 1:x:y:

z, the moisture content of the sand on site is m, and the moisture content of the stone is n, then the construction mix ratio is adjusted as: 1:(x-y*m-z*n):

y*（1+m）：z*（1+n）。

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.

Principles of concrete mix design:

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

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

3. Concrete should have good durability;

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

Basic requirements for designing concrete mixtures:

1. Meet the strength grade of concrete design.

2. Concrete and workability that meet the construction requirements.

3. Durability to meet the requirements of concrete use.

4. To meet the above conditions, save cement and reduce concrete costs.

The mix ratio of the laboratory is: cement: water:

Can you say the specific point This is according to the construction requirements, divided into pumping and non-pumping, and whether you want to use admixtures, a ratio has many factors to restrict It's not simply to say.

Summary. Hello, I am glad to answer for you, :C10 concrete ratio.

For example, the collapse of the concrete we took with C15 is 160 mm and 180 mm. At this time, the cement chosen is cement, and the sand is the middle sand of the river sand used. The diameter of the crushed stone is 20 mm to 40 mm.

Then at this time, the ratio of this concrete is about 320kg of cement, 825kg of river sand, 1090kg of gravel, 190kg of water, and admixtures. Here is the ratio of one cubic meter of concrete. At this time, the mix ratio is probably cement:

River Sand: Gravel: Water:

The ratio of admixtures is:

What is the conventional C10, C15, C20, C25, C30 concrete mix ratio?

Ratio of C15 concrete. For example, the collapse of the concrete we took with C15 is 160 mm and 180 mm.

At this time, the cement chosen is cement, and the sand is the middle sand of the river sand used. The diameter of the crushed stone is 20 mm to 40 mm. Then at this time, the ratio of this concrete is about 320kg of cement, 825kg of river sand, 1090kg of gravel, 190kg of water, and admixtures.

Here is the ratio of one cubic meter of concrete. At this time, the mix ratio is probably cement:river sand:

The ratio of crushed lithograph:water:admixture is.

Ratio of C20 concrete. If the collapse of C20 concrete is also 160 mm, 180 mm.

At this time, the cement is cement, the sand is also the medium sand in the river sand, and the gravel is 16 mm. Then the amount of 1 cubic concrete at this time is 355kg of cement, 790kg of river sand, 1090kg of gravel, 190kg of water, and admixture. At this point, their mix ratio is:

Ratio of C25 concrete. If the collapse of C25 concrete is also 160 mm, 180 mm.

Cement is also the choice of cement, and the sand is the middle sand of the river sand. The gravel is also of choice 16 mm. Then this is the amount in a cubic concrete, which is 390kg of cement, 755kg of river sand, 1090kg of gravel, 190kg of water, and admixtures.

At this point, the mix ratio is. : C30 concrete ratio.

For C30 concrete, if the slump is also 160 mm 180 mm, then the cement we choose is also cement, the sand is selected and the middle sand in the sand, and the gravel is also selected 16 mm. At this time, the materials for the weight of a cubic concrete are 430kg of cement, 720kg of river sand, 1085kg of gravel, 190kg of water, and admixtures. Then the mix ratio of this concrete is.
