Product Description

Cement grouting material agent concrete additives/grouting agent/concrete additives

ST-type tunnel by grouting agent polycarboxylate organic polymer material and inorganic composite materials made free of oxides, chlorides and other harmful components of steel powder products containing reducing inorganic material, reinforced protection. The product has no shrinkage, micro-expansion, high flow, self-compacting, very low bleeding rate, high filling, balloon Mo thin small diameter, high strength, rust rust, chlorine-free low-alkali, high adhesion, green excellent performance. The product is suitable for a variety of pore filling construction materials (including cement paste, mortar, concrete), especially in post-tensioned concrete tunnel grouting project.
