How to remedy the cavity in the pouring of the load bearing beam of the rural self built house?

You can clean it first, water the hole after cleaning, and then apply mortar or concrete.

Chiseling. We need to chisel out some of the particularly low strength concrete on the surface of the honeycomb surface. This is done all the way down to the dense part of the inside. In fact, to put it bluntly, the concrete with unqualified strength is chiseled first, and then chiseled all the way to the part with qualified strength.

Clean and water to moisten. After we have chiseled off some of the floating concrete on the surface, we have to clean up some of the crumbled concrete and rinse it with a water hose. Make sure the area is wet. Patching can only be done after that.

3.Mend. Fine stone concrete is used to fill the holes.

The so-called fine stone concrete is to use fine stone concrete that is more than one grade higher than our concrete load-bearing beam to repair the parts we chiseled. The conventional method is to take concrete with a high grade and then seal the part.

If this happens, we can take appropriate treatment methods, such as smearing or grouting the hole, and watering the hole while walking along the river to keep the hole moist.

Dear, slow burial Hello, I am glad to answer for you: how to remedy the cavity in the load-bearing beam of the self-built house? Answer: Hello, dear, the concrete beam reinforcement should pay attention to the main reinforcement, the payment reinforcement, the stirrups, the diagonal tendons, and the erection disturbance of the answering ribs, the most important of which is the main reinforcement.

When the lintel is designed, the diameter of the main reinforcement is generally not less than 20mm, and it is distributed about 50mm away from the lower skin of the beam (25-50mm of the protective layer). If the beam height is more than 500mm and the middle of the beam height is selected at the position of the drilling air hole, the main reinforcement of the lower layer will not be damaged, that is, there are steel fragments drilled out of the reinforcement and stirrups will not have a big impact, and the air hole can be used safely by blocking the air hole with cement. If a hole is punched in the lower layer of the beam height and the main reinforcement within the protective layer is destroyed, the consequences are serious, and there is only one remedy:

Peace and joy!

There is only one way, and it looks very simple, and that is to fill in the hole.

After the hole in this beam, there is no potential safety hazard at all for us to fill it, because although it produces a hole, it is a whole in other places, and it is poured with reinforced concrete, and the force that should be played has been played, and the remedy is just to make yourself psychologically comfortable and look good. There is no effect on the load-bearing.

However, although this remedy is only filled, it cannot be sloppy when filling, because of the particularity of cement, resulting in the two not being poured at the same time, it is easy to produce an unfavorable situation of combination.

Therefore, when we remedy, we should rinse the cavity surface well, rinse some ash and slag, and then rinse the cavity surface well, it must be wet, and the two cannot be combined at all when it is dry, and the things that are made up will shrink directly, or it will fall off.

1. The first step is to remove the concrete with cavities or non-compactness, and remove it to the dense part;

2. The second part will be cleaned of the removal surface, and the following interface agent can be brushed if conditions are possible 3, and the high-grade fine stone concrete (preferably reinforced with vibration-free high-strength concrete) is poured and compacted 4, and attention should be paid to maintenance.

The first step is to remove loose stones and concrete from the holes.

The second step is to clean it with water.

The third step is to fill it with concrete of a higher strength grade.

For example, if you are now C25, you can fill it with concrete with C30 strength grade, and if the hole is small, you can also fill it with high-strength cement mortar.
