| abstract |
The invention provides a high foam-stabilizing, low-sensitivity concrete air-entraining agent and a preparation method, belonging to the technical field of concrete admixture preparation. ～40%, viscosity modifier 2～4%, foam stabilizer 2～8%, synergist 1～3%, water 45～75%; Gemini surfactant and various functional components act synergistically to significantly improve foaming and foam stabilization capabilities. Compared with conventional air-entraining agents, it has the advantages of low dosage, high foam stabilization, and high adaptability to hard water, which can meet the requirements of high and cold conditions. Requirements for use in harsh environments such as low pressure. |
