The influence of high polymer (HP-SRA) on workability, mechanical property, volumestability, early-age cracking performance and chloride ion diffusivity of pumping concrete are comparatively investigated. The results show that HP-SRA has better water-reducing effect and slump in pumping concrete mixture. HP-SRA hasn’t a certain negative effect on the compressive strength, flexural strength and spliting strength of pumping concrete. HP-SRA can obvoiously reduce the drying shrinkage and early-age autogenous shrinkage of pumping concrete, and early-age crack resistance and chloride ion diffusivity of pumping concrete are reinforced drastically or improved efficiently.
