Roar Concrete segregation How to take measures Mixing plant

For non-structural parts, there are two solutions.

1. Put away the excess slurry and add the high-grade dry mortar.

2. Drop half of the concrete and add more than 2 marks of concrete.

For structural parts, this should be based on actual experience, and the above methods can be used, but it is not recommended.

By the way, sigh:

The first floor is brain-dead and can't understand the problem.

On the 2nd floor, your mother called you home for dinner!

The causes of segregation may be improper pouring and vibration, the maximum particle size of the aggregate is too large, the proportion of coarse aggregate is too high, the content of cementitious material and fine aggregate is too low, the density of coarse aggregate is too large compared with fine aggregate, or the mixture is too dry or too wet. The use of mineral admixtures or air-entraining agents can reduce the tendency to segregation. Note that the concrete mixing should comply with the specifications.

Re-pass and stir. It's all money. This time, you have to pay attention... If it helps, remember to give a good review.

After concrete segregation, you can use more cement, a layer of cement, a layer of gravel... In the future, the height of the concrete should not exceed 2 meters.

If it is not used for concrete of important main structures, add high-grade dry mortar, and then carry out forced mixing.

Continue stirring. Add admixtures. air-entraining agents, etc.

I don't know what the amount of superplasticizer you add is, maybe the amount of superplasticizer is too high.

The segregated concrete is considered a waste product.

Hello, I'm sorry to keep you waiting, I can only remedy it, if the concrete is segregated, we must first control the slump of the concrete out of the machine within a certain range, so as to reduce its slump, and then increase the mixing time of the concrete. Generally speaking, the segregated mixed concrete can also be stirred in the next step, but it also depends on the condition of its segregation. If the segregation is particularly severe, it can no longer be stirred, and it can only be invalidated.

If the concrete is segregated, then its feeding performance will be reduced. To put it simply, it is concrete, and its function of flowing and moving bridges is reduced. Because of the segregation, its own flow function is weakened.

As a result, the concrete will be blocked in the process of feeding. Basically, it's because the mixer is clogged, but it's also because of the segregation of concrete.

The segregation of concrete is that the cohesion between the constituent materials of the concrete mixture is not enough to resist the sinking of the coarse aggregate, and the components of the concrete mixture are separated from each other, resulting in uneven internal composition and structure. This is usually manifested by the separation of the coarse aggregate from the mortar, e.g. by the deposition of dense particles to the bottom of the mixture, or by the separation of the coarse aggregate from the mixture as a whole.

The causes of segregation may be improper pouring and vibration, the maximum particle size of the aggregate is too large, the proportion of coarse aggregate is too high, the content of cementitious material and fine aggregate is too low, the density of coarse aggregate is too large compared with fine aggregate, or the mixture is too dry or too thin. The use of mineral admixtures or air-entraining agents can reduce the tendency to segregation.

Concrete segregation: The components of the concrete mixture are separated from each other.

Summary. It is recommended to lower the label adjustment. One side of the tune.

That is, after beating one side and stirring, look at the workability, and then adjust it. If the concrete strength is not enough, it is necessary to add a special hardening enhancer for concrete, and the specific way to use it is to open the packaging bag of the product first, and then pour it into an idle plastic bucket, then mix it evenly with a wooden stick, and finally paint it on the surface of the concrete with a roller, or pour it directly into the sprayer after stirring evenly, and spray it on the concrete surface with a sprayer.

Trouble, novice, how to lower the label tone, say easy to understand some thanks, for example, there is a side of material segregation, how can I temporarily season, improve the state of segregation.

Cement is labeled.

Look. I know this, how to solve it, for example, I now find that there is more material and water separation, there are five square materials, I am now on the site, how to adjust it, I can make the concrete pour.

Are you there. Slowly add cement.

Is it okay to just add cement, so will this reduce the strength, no.

If the strength is not enough, add a reinforcer.

Look at the top one.

Thank you, slowly add cement, now there are five square materials, how much should I add at a time, can you give an example, I won't adjust it.

Less and add slowly.

How many pounds to add, is it half a bag or a bag, how much is this less, can you give an example, I'm sorry for you.

It depends on how much you have.
