To optimize the formulation of polymer grouting materials,improve their flowability and strength,reduce reliance on traditional cement and provide a novel and efficient construction material,this study systematically investigates the influence of four key factors-cement content,alkali equiva-lent,water-to-binder ratio,and superplasticizer dosage-on the flowability and strength of alkali-acti-vated kaolin-based polymer grouting materials using an orthogonal experimental design.Experimental results reveal that the best flowability of the polymer grouting material is achieved at a cement content of 45％,alkali equivalent of 7.8％,water-to-binder ratio of 0.77 and superplasticizer dosage of 0.75％.The highest strength of the polymer grouting material is obtained at a cement content of 45％,alkali equivalent of 7.8％,water-to-binder ratio of 0.75,and superplasticizer dosage of 0.75％.A-mong these four factors,alkali equivalent and superplasticizer dosage exert the most significant influ-ence on flowability,while cement content and alkali equivalent play dominant roles in strength.
