Mix ratio of concrete, concrete mix ratio

According to the number of concrete, choose cement first

Low Grade: High Grade.

Sand: Medium sand. Stones: Graded stones.

According to the water-cement ratio and moisture content, adjust the mix ratio.

Concrete mix ratio refers to the proportion of raw materials such as cement, aggregate, sand, water, etc., which is the most basic parameter in concrete engineering and is directly related to the performance and quality of concrete. The concrete mix ratio should be designed and adjusted according to the specific situation, and the common concrete mix ratio is as follows: 1. Ordinary concrete mix ratio:

The ratio of cement, sand and aggregate is 1:2:3, and the water-cement ratio is 1:2:3, which is suitable for general concrete engineering.

2. High-strength concrete mix ratio: the proportion of cement, socks only sand and aggregate is, and the water-cement ratio is, and the gap is suitable for high-strength concrete projects such as bridges and high-rise buildings. 3. Self-compacting concrete mix ratio:

The ratio of cement, sand and aggregate is and the water-cement ratio is suitable for groundwater engineering and basement. 4. Ultra-high-strength concrete mix ratio: the proportion of cement, sand and aggregate is the ratio of water-cement and water-cement ratio, which is suitable for large-scale water conservancy projects, nuclear power plants and other high-strength concrete projects.

5. Lightweight concrete mix ratio: the proportion of cement, lime, expansion agent, sand, aggregate and water is designed according to the need, which is suitable for sound insulation, heat preservation, fire prevention and other fields. <>

It should be noted that the concrete mix ratio should be designed and adjusted according to the specific situation, and should be comprehensively considered according to factors such as the construction process, the nature of raw materials, and the performance of the concrete requirements.

1. If it is a C20 model, the proportion of concrete on one side is 1261kg of stone, 621kg of sand, 343kg of cement and 175kg of water.

2. The proportion of C15 model is.

3. The proportion of concrete on one side of C25 is.

How to match the ratio of concrete, I believe you know less about this knowledge, so let's take you to understand it.

First, how to match the concrete ratio.

1. If it is a C20 model, the proportion of concrete on one side is about 1261kg of stone, 621kg of sand, 343kg of cement, and 175kg of water.

2. The proportion of C15 model is.

3. The proportion of concrete on one side of C25 is.

The basic ratio of concrete is the proportion of cement, water, sand and stone that meet the quality requirements, and the proportion of these raw materials according to the actual strength of cement and the concrete that needs to be of the strength grade. This ratio is expressed in terms of the weight of various raw materials required for each cubic meter of concrete. This ratio is obtained by the testing and trial matching of various raw materials entering the site through the testing station (company).

The basic ratio here refers to the mix ratio without the addition of admixtures.

List of concrete mix ratios:

<> so-called concrete construction mix ratio refers to the ratio of dismantling beams and respecting the mix used in the construction process of concrete concrete in the construction process.

Adjustment steps: set the laboratory mix ratio to cement: sand.

Stone = 1:x:y, the moisture content of the sand on site.

is m, the moisture content of the stone is n, then the construction mix ratio is adjusted as: 1:x (1-m):y (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.

Summary. For example, if C30 grade concrete, 325 cement or 425 cement, gravel, stones, water and other materials are generally used, and the proportion is: That is to say, if the cement used is 100 grams, then the grit needed is 118 grams, the stones are 263 grams, and the water is 41 grams

Hello, dear <>

I am a co-teacher who asks Wu Manzhou, and I am good at social and people's livelihood news hotspots, life consultation, and entertainment focus. The people's livelihood refers to the sum of the people's basic survival and living conditions, as well as the people's basic development ability, basic development ability, and protection of basic rights and interests. People's livelihood is the core work of the world, including clothing, food, housing, transportation, birth, old age, sickness and death.

For example, if C30 grade concrete, 325 cement or 425 cement, gravel, stones, water and other materials are generally used, and the proportion is: the laughing stool stove That is to say, if the cement used is 100 grams, the sand and gravel that need to be used for rough flushing is 118 grams, the stone is 263 grams, and the water is 41 grams

Pro, now the composition of ordinary concrete is mainly cement, You's simple admixture (fly ash, mineral powder, nuclear silica fume, etc.), sand, gravel, water, admixtures The concrete mix ratio is the proportion of these materials required when configuring concrete

Pro, the main chain of concrete mix ratio is the water consumption, water-glue ratio, cementitious material dosage, the amount of leakage and dosage of the mixture before the shed, the sand rate, the type and amount of admixtures

Dear, the following is a brief introduction to concrete concrete, referred to as"Concrete (tóng)."The word "concrete" usually refers to the use of cement as cementitious material, sand and liquid traces of Kai Yushi as aggregate, and water (can contain admixtures and admixtures) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete, which is widely used in civil engineering.

Dear, Gaoxin, I am glad to answer for you: concrete mix ratio refers to the ratio of concrete materials, including cement, sand, gravel, aggregate and some adjusting materials, their proportion and dosage are the key factors of concrete quality. The determination of the concrete mix ratio is reasonable and practical, and to meet the requirements of the quality of concrete engineering, the specific mix ratio should be determined according to the use of concrete, construction technology and construction environment.

In general, the mix ratio of concrete should be based on cement and expressed in proportion, such as "1:2:4", which means cement:

The ratio of sand:gravel is 1:2:

4. Among them, "1" represents the amount of cement, "2" represents the amount of sand, and "4" Qi Dalun represents the amount of gravel, which can also be expressed by weight ratio or volume ratio. In addition, some adjusting materials can also be added to the concrete mixture, such as fly ash, slag, mineral powder, fly slag imitation aging, fly ash, etc., to adjust the fluidity, durability and fire resistance of concrete to meet different engineering requirements. Thank you for your trust, the above is my reply, I hope it can help you, I wish you a happy life

175kg cement: 398kg sand: 566kg stone:

The mix ratio of 1261kg is::1:: water:

175kg cement: 461kg sand: 512kg gravel:

The mix ratio of 1252kg is::1::

According to the strength grade of concrete, the ratio is different. Common grade ratio C20 water: 175kg cement:

343kg sand: 621kg stone: 1261kg The mix ratio is::

1:: Water: 175kg cement:

398kg sand: 566kg stone: 1261kg The mix ratio is::

1:: Water: 175kg cement:

461kg sand: 512kg stone: 1252kg The mix ratio is::

1::What is the proportion of concrete formulation?There are differences in the proportion of concrete formula of different strengths, for example, the mix ratio of C15 concrete is 246 kg of cement, 767 kg of sand, 1199 kg of stones, 175 kg of water, that is, 1 ratio. Its formula ratio refers to the quantitative relationship of various materials in concrete, and it is also closely related to the smoothness, quality and cost of concrete construction.
