MasterMatrix 220

Rheology Modifying Additive for Concrete and Shotcrete

How Does MasterMatrix 220 Work?

MasterMatrix 220 is an innovative additive that modifies rheology in a wide variety of concrete products and cement-based applications. MasterMatrix 220 is an ultra-fine mineral-based powder containing bundles of sub-micron particles.

Areas of Application

• Tremie concrete for piles and diaphragm walls

• Super Workable Concrete and Self-Compacting Concrete

• Shotcrete

• Precast concrete

• Manufactured concrete products (blocks, pavers, and retaining walls)

• Underwater concrete

• Mortar and grouts

• Geopolymer concrete

What Makes MasterMatrix 220 a Unique Solution?

When well dispersed in wet cementitious materials, the particles interact to form a network that entraps liquid and smaller cementitious particles and keeps larger particles suspended.

What Are the Benefits of MasterMatrix 220?

• Provides control of bleed water

• Reduces potential for segregation

• Improves paste quality, cohesion, and rheology

• Imparts some anti-washout properties

• Improves pumpability of concrete and grouts

• Reduces shotcrete rebound

• Improves surface consolidation and finish

Note: MasterMatrix 220 may affect water content, target slump, and admixture dosage, depending upon temperature and their proportions. Lab and field trials should be conducted to achieve the desired performance.
