The invention belongs to the technical field of grouting agents, and particularly relates to a novel grouting agent which comprises the following components in parts by weight: 7-20 parts of a water reducing agent, 1-3 parts of an air entraining agent, 3-7 parts of a thixotropic agent, 2-5 parts of a defoaming agent, 3-6 parts of a thickening agent and 13-22 parts of an expanding agent. The grouting agent provided by the invention has the characteristics of efficient water reduction, enhancement, plasticity maintenance and good bleeding reduction effect in use, and can cause micro-expansion ofa cement mixture before setting, fully fill gaps and generate micro-expansion after cement hardening to compensate shrinkage generated by cement hydration.
本发明属于灌浆剂技术领域，尤其为一种新型灌浆剂，按照重量份组成为：减水剂7‑20份、引气剂1‑3份、触变剂3‑7份、消泡剂2‑5份、增稠剂3‑6份、膨胀剂13‑22份；本发明中的灌浆剂在使用时具有高效减水、增强、保塑以及降低泌水效果好的特点，并且可引起水泥拌合物在凝结前微膨胀，充分填充空隙以及在水泥硬化后可产生微膨胀，补偿水泥水化产生的收缩。
