Anti-frost-crack concrete expansive agent and preparation method thereof
The invention discloses an anti-frost-crack concrete expansive agent and a preparation method thereof. The anti-frost-crack concrete expansive agent is mainly prepared from components in parts by weight as follows: 13-28 parts of quicklime, 11-24 parts of gypsum, 8-17 parts of fly ash, 8-21 parts of silicon dioxide, 12-23 parts of silicon carbide, 8-20 parts of polypropylene, 4-12 parts of polyacrylamide, 7-14 parts of aluminum sulfate, 3-9 parts of aluminum potassium sulfate, 2-7 parts of an activating agent, 5-12 parts of methanol and 20-35 parts of water. Compared with the prior art, the anti-frost-crack concrete expansive agent has the following advantages: (1), the prepared anti-frost-crack concrete expansive agent has good anti-frost-crack performance and is applicable to building materials in cold regions; (2), the prepared anti-frost-crack concrete expansive agent has high water resistance and is applicable to submerged structure filler.
