Supershield ADMIXPLUS
Self-healing Adaptive Liquid Crystalline Waterproofing Admixture for Concrete
ADMIXPLUS is a high-performance liquid crystalline admixture powered by Adaptive Crystalline Technology, designed to enhance concrete durability from casting throughout its service life. When added to the concrete mix, ADMIXPLUS activates SHIELD Adaptive Crystals that begin working during early hydration. These dynamic crystals regulate internal moisture in both hot and cold conditions, support uniform cement hydration, and help control peak temperatures and thermal gradients—reducing early-age thermal stress and shrinkage cracking. As concrete matures, the crystalline network continues developing within pores and capillaries, refining the internal structure and reducing permeability. The system remains active over time, adapting to changing environmental and exposure conditions while regulating moisture movement, vapour behaviour, and temperature.
Applications
Basements, Concrete Water Tanks, Tunnels and Subway Systems, Roof Slab, Sewage and Water Treatment Plants, Reservoirs, Sunken Portion, Foundations & Elevator pits, Ground parking structures, Bridges and dams
Features and Benefits
| Features | Benefits |
|---|---|
 Liquid crystalline admixture | Blends easily and accurately into RMC and on-site mixes, ensuring consistent dispersion and performance. |
| VOC-free, water-based formulation | Non-toxic, eco-friendly, and contributes to LEED and green building compliance. |
| Enhances fresh and hardened concrete properties | Enables smooth placement and uniform finish even under challenging jobsite or climate conditions, without altering mix design. |
| Permanent waterproofing by sealing internal pores/capillaries | Improves impermeability, providing long-lasting internal waterproofing from within the concrete matrix. |
| Regulates hydration and moisture | Ensures optimal hydration, promoting strength development and minimizing early-age cracking. |
| Densifies the ITZ through moisture regulation | Strengthens the paste-aggregate interface, reducing porosity and increasing overall durability. |
| Enhances hydration to promote C–S–H development | Reduces free lime formation, increases C–S–H gel development, and minimizes capillary porosity, improving microstructural stability and reducing risks of efflorescence and chemical vulnerabilities such as alkali-silica reaction (ASR). |
| Regulates hydration temperature | Helps reduce the risk of Delayed Ettringite Formation (DEF) and associated expansion by controlling hydration temperatures. |
| Manages thermal gradients | Reduces thermal stress and shrinkage cracking in mass concrete by optimizing internal heat distribution. |
| Manages phase changes in concrete | Dynamically responds to temperature, moisture, and phase changes within concrete. |
| Adapts to environmental changes throughout the concrete’s lifecycle | Sustains durability by responding to environmental conditions such as drying, rewetting, freeze-thaw cycles, and thermal fluctuations. |
| Self-heals micro-cracks up to 0.5 mm | Restores structural integrity and extends service life by autonomously sealing micro-cracks. |
| Resists chemical attack | Protects against deterioration caused by aggressive agents such as chlorides and sulfates. |
| Freeze-thaw resistance | Prevents freeze-induced cracking by sealing internal pores and significantly reducing permeability, thereby minimizing water ingress and internal expansion. |
| Carbonation resistance | Enhances impermeability and reduces free lime, helping preserve concrete alkalinity and protect embedded steel from corrosion. |
| Compatible with modern concrete formulations | Supports use with blended cements (fly ash, slag), making it ideal for sustainable and performance-driven mix designs. |
