How to determine the ratio of concrete in concrete batching plant??? Who s going to !!!!!!!!

The mix ratio is calculated according to the strength grade.

Hubei Province has this software.

Fitting strength FCUO = FCUK+

W c = FCE FCUA+ A* B*FCE determines the sand rate according to the slump, and then uses the following two methods to calculate.

Plausible gravimetric method.

MCO + MGO + MSO + MWO = MCPs = ( MSO (MSO + MGO))) * 100% absolute volume method.

mco / ρc + mgo / ρg + mso /ρs + mwo /ρw +

s = ( mso (mso + mgo)))*100% common mix ratio is this calculation method without any external mixing.

No, the ratio is a complicated thing, the materials are all different, and there is no formula. If you want to confirm that he is correct, you should do the test block according to his ratio, and then test the pressure when it expires to achieve the strength required by the design, which is correct. And do the slump according to the ratio to see if it meets the requirements! FYI!

The landlord said that there is software, but the specific ratio inside should be designed in advance by the laboratory to make a reserve, and then call different ratios according to the specific situation.

Since the raw materials used in each mixing plant are different, the ratio of this one is reasonable, and there may be problems when placed in another.

However, some large principled parameters, such as the water-cement ratio, etc., can not be wrong, and this can also be reversed by the mix ratio in the "Quality Certificate" of the mixing plant.

Yes, but they are not allowed, and the mix ratio that comes out cannot be used.

So far, I haven't found a reliable similar software.

I personally haven't heard of that software.

Others don't know.

You go to the lab and you can do the math and you can get the construction mix.

Just enter it into the electronic aggregate machine of the mixing plant, and adjust it appropriately according to the mud content and moisture content of the sand and gravel.

1. The concrete laboratory mix ratio is cement: sand: stone: water = 1::: when the moisture content of the sand on site is 3%, the mass of the sand =, when the moisture content of the stone is 1%, the mass of the stone = , and the quality of the water should be reduced to =

Therefore, the construction mix ratio is cement:sand:stone:water = 1:::

liters = cubic meters, mixer (discharge capacity) is 250 liters, i.e.

Because the amount of cement per cubic meter of concrete is 290kg, the actual capacity is now timely, and cement is needed.

According to the construction mix ratio: cement: sand: stone: water = 1:::

That's all for the amount of material needed.

1. 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 adjustment implicit slag is: 1: (x-y*m-z*n):

y*（1+m）：z*（1+n）。

2. Concrete mix design is a very important work in concrete engineering, which directly affects the smooth operation of concrete, the quality of concrete engineering and the cost of concrete engineering.

Amount of material per cubic meter: water: 190 cement: 500 sand: 479 stone: 1231

The mix ratio is::1: sand rate 28% water-cement ratio:

The 14 strength grades commonly used in general engineering are C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80.

The strength grade is determined according to the standard value of the compressive strength of the cube. The concrete strength grade is also an important basis for the design of concrete structures, construction quality control and engineering acceptance. Different engineering structures and different parts of the building should need to choose concrete with different strength grades.

1. The concrete mixing budget of highway engineering and highway engineering that must set up a mixing plant can only be budgeted according to the mixer.

a) Highway works where a mixing plant must be set up.

The highway engineering of the highway pavement with a large amount of concrete engineering, a long construction period and concentrated construction must be set up with a mixing plant, and a mobile mixing plant must be set up.

2) The budget for concrete mixing of highway engineering can only be budgeted according to the mixer.

In the budget, there is no separate item in the road quota, which is included in the concrete, that is, the budget is made by mixer.

2. Concrete batching plant.

a) Definitions. The concrete batching plant is mainly composed of 5 major systems and other ancillary facilities, including the mixing host, material weighing system, material conveying system, material storage system and control system. Because the building aggregate metering is compared with the station aggregate metering, four intermediate links are reduced, and it is a vertical blanking metering, which saves the measurement time, so the production efficiency is greatly improved, and in the case of the same model, the production efficiency of the mixing building is increased by one-third compared with the production efficiency of the mixing plant. For example:

The production efficiency of the HLS90 floor is equivalent to the production efficiency of the HZS120 station, the production efficiency of the HLS120 floor is equivalent to the production efficiency of the HZS180 station, and the production efficiency of the HLS180 floor is equivalent to the production efficiency of the HZS240 station.

b) Role. Concrete batching plant is a combined device used to mix concrete centrally, also known as concrete precast yard. Due to its high degree of mechanization and automation, the productivity is also very high, and it can ensure the quality of concrete and save cement, and is often used in large and medium-sized water conservancy, electric power, bridges and other projects with large concrete engineering quantity, long construction period and concentrated construction site. With the development of municipal construction, the mixing plant that adopts centralized mixing and provides commercial concrete has great advantages, so it has developed rapidly, and creates conditions for the promotion of concrete pumping construction and the joint operation of mixing, conveying and pouring machinery.
