Abstract
The present invention discloses an optimized preparation method of a carbonization-based lightweight COfoamed cement-based material, and belongs to the field of geotechnical engineering materials. The preparation method includes: step S: pre-screening existing common cement-based foaming agents and foam stabilizers; step S: preparing a water-based carbon dioxide foam; step S: preparing a cement slurry, and mixing the water-based carbon dioxide foam with the cement slurry to prepare a lightweight COfoamed cement-based material; step S: selecting foaming agents of different types and different concentrations and foam stabilizers of different types and different concentrations to prepare slurries, subjecting the slurries to slurry performance tests, and selecting the optimal ones; step S: optimizing initial water-to-cement ratio and foam-to-slurry ratio parameters; and step S: optimizing a gas-filling volume parameter (water pump speed).
