Repair of concrete column cavity

If there is a cavity in the concrete column, the following remedial measures can be considered:

Filler repair: injecting concrete cavity filler into the cavity can fill the cavity and restore the strength and appearance of the column. The filler can be made by ourselves or purchased, but the strength and durability of the filler should meet the requirements.

Epoxy resin repair: epoxy resin can be used to fill concrete cavities with excellent adhesion and durability. Epoxy resin can be mixed and sprayed into the cavity to form a solid coating, which can effectively fill the cavity and enhance the strength and durability of the column.

Repair of sprayed concrete: sprayed concrete can fill concrete cavity, which has the advantages of fast repair speed, high strength and good durability. Sprayed concrete needs professional equipment and technology to ensure the strength and uniformity of concrete.

Carbon fiber repair: carbon fiber can be used to repair the cavity of concrete columns, which has the advantages of high strength, high durability and corrosion resistance. Sticking carbon fiber cloth or sheet around the cavity can enhance the strength and durability of the column and effectively fill the cavity.

The above methods need to be selected according to the specific conditions of the concrete column cavity, and the cavity needs to be thoroughly cleaned before repair, and the bonding force and durability of the repair material should meet the requirements.
