Composite concrete air entraining agent, and preparation method and application thereof
The invention provides a composite concrete air entraining agent, and a preparation method and application thereof. The invention is characterized in that the composite concrete air entraining agent is composed of a sulfonate Gemini surfactant, a betaine amphoteric surfactant, an alkanolamide nonionic surfactant and water; and the solid content of the composite concrete air entraining agent is 20+/-1%. The composite concrete air entraining agent has excellent air-entraining effect in concrete; and sufficient 20-150-mu m stable small bubbles can be introduced to improve the workability of the concrete (mortar), reduce the bleeding rate and sedimentation and avoid lowering the later strength of the concrete on the premise of enhancing the air content.
