The mix ratio of one cubic C30 concrete is: 1::

Among them, water is 175kg, cement is 461kg, sand 5 is 12kg, and gravel is 1252kg.

C30 concrete refers to the use of cement as cementitious materials, sand, stone as aggregates scattered potatoes, and water (with or without admixtures and admixtures) in a certain proportion, through mixing, molding, curing, hardening and obtaining a certain structural strength of the structure or component, also known as cement concrete, it is widely used in industrial and civil buildings and general structures mix design of the basic data.

Expansion of the capital is expected:

Precautions when preparing concrete:

1. At least three different mix ratios should be used in the concrete strength test. When different mix ratios are used, the water-glue ratios of the other two mixtures should be increased and decreased respectively compared with the benchmark mix ratios. The water consumption is the same as the benchmark mix, and the volume fraction of the sand can be increased or decreased by 1%, respectively.

2. When making concrete strength test specimens, it should be verified whether the self-compacting performance of the mixture meets the design requirements, and the results should represent the performance index of the concrete mixture with the corresponding mix ratio.

3. At least one group of specimens should be made for each mix ratio excavation during the concrete strength test, and the standard curing to 28d or the age required by the design should be tested for pressure, and several groups of specimens can also be made at the same time, and the corresponding durability index should also be tested if there are durability requirements.

What is the mix ratio of one cubic C30 concrete?Dear!Hello, I am glad to answer for you<> pro-one cubic C30 concrete fit such as the following:

Generally sober. If it is a cubic C30 concrete that is manually mixed, it is generally necessary to mix according to the ratio, of which the amount of cement is generally 461 kg, the amount of water is generally 175 kg, the amount of sand is generally 512 kg, and the amount of stone is generally 1252 kg. I hope my life can help you <>

Do you have any other questions?

c30Concrete mixtureYes:1::Concrete:

512kg, stone and open: 1252kg.

There are two ways to express the ratio of C30 concrete: one is to use the amount of various materials in 1 cubic meter of commercial concrete, such as 300 kg of cement, 180 kg of water, 690 kg of sand, and 1260 kg of stoneThe other is the ratio of cement per unit mass to the amount of various materials and the water-cement ratio of commercial concrete.

For example, the precedent can be written as: c:s:g=1::,w c=.

General Warranty. C30 concrete strength.

The measures are mainly guaranteed from the following aspects:

1. Process: From the mixing, transportation, mold and vibration of concrete, the construction must be carried out in accordance with the corresponding process standards.

3. Machinery: Coagulation and soil mixing, pouring and transportation machinery must meet the actual needs.

4. Personnel quality: must have a sense of responsibility.

And only those with relevant professional qualifications can carry out relevant operations.

5. Link control: on-site management personnel must go to the site to inspect and stand next to the station to ensure the qualified requirements of each link. In terms of strength, C30 concrete should be required to be qualified in order to be qualified.

Summary. C30 concrete mix ratio requires about 400 kilograms of cement per cubic meter.

C30 concrete mix ratio, how much cement per cubic meter?

C30 concrete mix ratio requires about 400 kilograms of cement per cubic meter.

When using one cubic meter of C30 concrete for modulation, it is generally necessary to add about 400 kilograms of cement to Changhe Yuan, about 512 kilograms of sand, and about 1,252 kilograms of stone to collapse, and then carefully and fully stir until there are no bubbles in the mixture.

One cubic meter of C30 concrete needs to be used: cement 530kg, medium sand m, stone (<16mm) m, water m. Hope it helps.
