Abstract With the continuous development of economy, engineering construction is developing towards deep high-stress area, and problems large-deformation are becoming more serious. Anchoring grouting a very effective support reinforcement method. The anchoring materials used in project mainly cement paste mortar. characteristics material have decisive influence on effect. However, it difficult for existing to satisfy requirements strength deformation at same time, improvement urgently needed. Polycaprolactone (PCL) an organic polymer good properties, including high ductility, stability strong impact resistance. In this paper, PCL was added as auxiliary additive cement-based innovatively, mechanical test micro-test PCL-cement-based were carried out. results show that adding can significantly increase compressive paste. By adjusting content PCL, ductility mortar be effectively improved. When 15%, ideal performance obtained. Anchor
