A high-performance additive to prepare flowable, high-strength, non-shrink cementitious grouts using local cement and sand.
Summary Benefits at a Glance:
Flexible Use – Converts local cement and sand into high-performance grout
High Strength – ≥20 MPa (1d), ≥40 MPa (3d), ≥60 MPa (28d)
Non-Shrink Expansion – Stable volume with zero bleeding
Excellent Flowability – Easy placement, even in dense reinforcement areas
Product Introduction
CBGM-300 Cementitious Grouting Additive is engineered to simplify grouting preparation while maintaining international standards of performance. When mixed with local cement and sand, it produces a high-strength, flowable, and non-shrink grout comparable to factory-produced cementitious grouts.
Its unique formulation provides early and final strength, excellent fluidity, zero bleeding, and corrosion resistance, ensuring long-term durability. This solution significantly reduces logistics cost and increases flexibility for wind turbine foundations, machinery baseplates, anchorage systems, and civil or industrial infrastructure repair projects.
