When performing concrete crack repairs, the following points should be noted:

Prior to repair, the cracks must be cleaned to ensure they are clean and dry, allowing the repair material to bond securely to the concrete surface.

Select the appropriate repair method and materials based on the type and severity of the crack.

After repairs are completed, the repaired areas require maintenance, such as keeping them moist and avoiding external impacts, to ensure the durability of the bridge concrete crack repairs.

Please note that the above methods are general guidelines and should be adjusted according to specific circumstances. When repairing concrete cracks, it is recommended to seek assistance from an engineer or a construction crew to ensure the quality and effectiveness of the repair.

Measures for Corn Kernel Breakage Prevention

1) Templates must be thoroughly dried or coated with a smooth feed agent prior to concrete construction, and after the concrete is set, it should be carefully watered for cleaning.

2) When dismantling the non-load-bearing side formwork, the concrete should possess sufficient strength.

3) Do not force or rush the mold removal. Be cautious to protect the wedge shape; when hoisting, strictly prohibit the mold from hitting the wedge shape.

4) Reinforced concrete for protection.

For minor chipped or corner defects, clean the area with a wire brush after rinsing with clean water. Allow it to dry thoroughly, then fill and level the gap with stone mortar mixed at a ratio of 1:2 or 1:2.5. Remove any loose concrete and protruding hard particles, wash the area clean and dry, and then repair with fine sand concrete M30i, which is one grade higher than the original concrete, ensuring thorough and detailed cleaning.

Cement: Cement is one of the primary components of concrete, and different types of cement can affect the color of the concrete. To minimize color variation in concrete, opt for lighter-colored, lower alkali cement varieties such as slag cement or ordinary slag cement.

Aggregate: Aggregate is the part that occupies the volume in concrete, and its color, type, and particle size distribution all affect the color of the concrete. To minimize color variations in concrete, it is recommended to use aggregates with even color and good particle shape, such as natural river sand and manufactured sand.
