Microfine Cement (SuperFine) is an ultrafine blast furnace slag-based cement designed for specialty grouting applications. With a D95 particle size of 10 microns and a D50 particle size of 3 microns, it enables deep penetration into fine soil pores and microscopic rock fissures. This improves ground strength, reduces permeability, and enhances the effectiveness of water cut-off and consolidation grouting operations.

Key Features

• Ultrafine Particle Size Distribution: Median size of 3 μm enables excellent penetration into fine soils and rock fissures.

• High Strength and Durability: Produces grouts with strong in-place performance and long-term stability.

• Adjustable Mix Design: Water/cement ratio and superplasticizer type/dosage can be tailored to meet specific project requirements.

• Chemical and Brine Resistance: Performs reliably in aggressive environments, including those with high sulphate content.

• Proven Field Performance: Backed by a long history of successful grouting projects in challenging conditions.

SUPERPLASTICIZER (MIGHTY 150)

Superplasticizer Mighty 150 is a high-range water-reducing admixture used to improve the flowability and workability of Microfine Cement grouts without increasing water content. By enhancing particle dispersion and reducing viscosity, it enables higher injection pressures, deeper penetration, and superior strength development in fine soils and tight fissures.
