Grouting materials are widely used in construction engineering for foundation reinforcement, crack repair, and other fields. However, bubble problems often occur during the preparation and use of grouting materials. The presence of bubbles can affect the density and strength of the grouting material, reducing its reinforcement effect.

Therefore, finding effective solutions for defoaming grouting materials is of great significance.

A combination of physical and chemical methods can be used to solve the problem of bubbles in grouting materials. Physical methods include adjusting stirring speed, optimizing infusion process, etc; Chemical methods mainly rely on the addition of defoamers. By selecting and using defoamers reasonably, bubbles in grouting materials can

be quickly and effectively eliminated.

When using defoamers, attention should be paid to their compatibility with other additives to avoid adverse reactions. At the same time, it is necessary to choose the appropriate type and dosage of defoamer according to the type of grouting material and construction conditions.
