Cement Grout Additive is a versatile admixture that enhances cementitious grouting process. It reduces the water/cement ratio and promotes positive expansion, making it ideal for bed grouting, duct grouting, infilling, and jointing. This expanding grout additive, supplied as a powder, blends a plasticizing agent and a gas-producing expansion medium. The plasticizing agent enables a lower water/cement ratio, boosting strength and durability, while the expansion medium counters settlement and plastic shrinkage, enhancing stability. This product is perfect for pressure/injection grouting, improving flow, cohesion, and non-shrink properties in a variety of applications like pre-stressed cable ducts, rock anchoring, bearing plates, aggregates, and tunnel linings.
