Prestressed duct grouting material
The invention discloses a prestressed duct grouting material. The technical scheme is as follows: the prestressed duct grouting material is characterized by comprising the following components in parts by mass: 600-700 parts of cement, 200-300 parts of heavy calcium carbonate powder, 50-100 parts of micro silicon powder, 2-4 parts of water reducer, 0.5-1.2 parts of defoaming agent, 0.3-0.6 part of expanding agent and 0.5-1.0 part of suspending agent. The cement is 42.5 ordinary Portland cement. The invention aims to provide a no-shrinkage micro-expansive prestressed duct grouting material with ultra-fast flowability to prevent stratification.
