More Information
Summary:The invention relates to the technical field of building materials, and discloses an anti-efflorescence caulking compound based on glass powder. The high-strength concrete is prepared from the following raw materials in parts by mass: 2-9 parts of waste glass powder, 40-60 parts of a cementing material, 0.5-1.5 parts of an organic silicon water repellent, 0-0.5 part of a water reducing agent, 0.25-1 part of redispersible rubber powder, 0-0.2 part of cellulose ether, 0-0.5 part of zinc stearate, 0.01-0.05 part of a defoaming agent and 40-60 parts of fine aggregate. The saltpetering-preventing caulking compound based on the glass powder not only can prevent primary saltpetering, but also can prevent secondary saltpetering, really achieves long-term saltpetering prevention, is in a dormant state without water, acts once water permeates into the caulking compound, adsorbs alkaline ions to form a product, achieves a permanent alkali fixation effect, and meanwhile, enables the whole material to have hydrophobicity,
