​MasterMatrix 220

Rheology modifying additive for concrete & 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.

MasterMatrix 220 is recommended for use in a variety of applications requiring rheology modification and control such as:

• Tremie concrete for piles & diaphragm walls
• Super Workable Concrete & Self Compacting Concrete
• Shotcrete
• Precast concrete
• Manufactured concrete products (blocks, pavers & 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 & rheology
• Imparts some anti-washout properties
• Improves pumpability of concrete & grouts
• Reduces shotcrete rebound
• Improves surface consolidation & finish

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 desired performance.
