Flagship Product
PozzoDyne™ — engineered to perform.
AggrePlex's flagship product, PozzoDyne™, is an Activated Ground Glass Pozzolan (AGGP) — a next-generation supplementary cementitious material engineered to enhance concrete performance, reduce embodied carbon, and provide a reliable, consistent, and locally sourced cement replacement.

What is PozzoDyne™?
Ultra-fine. Engineered. Consistent. Repeatable.
PozzoDyne™ is an Activated Ground Glass Pozzolan (AGGP) manufactured from post-consumer and post-industrial glass feedstocks. Through AggrePlex's proprietary processing technology, the material is cleaned and precision micronized into an engineered particle-size distribution that delivers exceptional performance in cementitious systems.
As a supplementary cementitious material, PozzoDyne™ can replace 20–30% of ordinary Portland cement in the concrete matrix — reducing embodied carbon while maintaining or improving concrete performance.
Product Specifications
Precision by design.
PozzoDyne™ is produced to a precisely engineered particle-size distribution, optimized to maximize pozzolanic reactivity, concrete performance, and consistent results across a wide range of mix designs.
PozzoDyne™
D97≤ 20 microns
D50≤ 7 microns
Engineered to deliver an optimized balance of strength development, durability, cement replacement, and workability through the delivery of a consistent, ultra-fine particle-size distribution.
Manufactured using AggrePlex's proprietary micronization technology to ensure consistent quality, engineered reactivity, and repeatable performance from batch to batch.
The comparison
Where the industry stops, we start.
The industry's average ground-glass pozzolan is milled to about 45 microns. PozzoDyne™ begins there and keeps going — down to 3 microns, multiplying reactive surface area along the way.

Built for scale
Performance that survives contact with reality.
The concrete industry doesn't need another technology that may reach commercialization years from now — it needs solutions that can be implemented today. Ours is designed for scale from the start.
Built on proven manufacturing technology, precision particle engineering, and abundant regional feedstocks, PozzoDyne™ delivers a reliable, local, and scalable supplementary cementitious material ready for commercial deployment.
Micronized glass · PozzoDyne™Sustainability, simplified
A greener build without the trade-off.
By converting underutilized glass into high-value SCMs, we cut reliance on carbon-intensive raw materials and extend the life of resources already in circulation.
PozzoDyne™ draws on a readily available feedstock — enabling long-term scalability and genuine material security.

Competitive Advantage
Better concrete, from the inside out.
Engineered reactivity. Measurable results. Every advantage below is grounded in third-party UCPRC Lab2Slab test data or the measured properties of the material itself.
01
02
Long-term strength growth
Exceeds 10,000 psi by 42 days (~90% above control) as continued pozzolanic reaction adds strength beyond conventional curing periods.
03
Flexural strength
More than 1,150 psi modulus of rupture by 56 days — about 2× the control mix and well above the Caltrans 42-day minimum of 650 psi.
04
Durability & low permeability
~4.5× higher bulk electrical resistivity than the control by 56 days — the standard indicator of resistance to chloride ingress and reinforcement corrosion.
05
Lower drying shrinkage
~37% lower shrinkage than the control at 28 days, staying below the Caltrans 0.05% limit that the control mix exceeded.
06
ASR mitigation
ASR expansion held below the ASTM C1778 limit throughout testing (~0.08% at 28 days), indicating good resistance to alkali-silica reaction.
07
Denser concrete
Measured fresh unit weight of ~152.8 lb/ft³ versus ~145.8 for the control in Lab2Slab testing — a denser matrix from ultra-fine particle packing.
08
Engineered fineness
Precision micronization delivers 98%+ passing the No. 325 sieve with controlled particle-size distribution — qualified per ASTM C1866.
09
Extended service life
The measured combination of higher strength, higher resistivity, and lower shrinkage supports longer-lasting, lower-maintenance structures.
10
Brighter concrete
The naturally light color of PozzoDyne™ produces brighter concrete, enhancing aesthetics and increasing solar reflectance.
This is not just a cement replacement — it's a performance upgrade to conventional concrete.
Sustainability
Lower carbon. Smarter materials. Scalable impact.
LCA Key Finding
Up to 94%
reduction in CO₂ emissions per ton produced compared to Ordinary Portland Cement (OPC), validated through independent Life Cycle Assessments (LCAs).
CO₂ reduction through cement replacement
Cement is the most carbon-intensive component of concrete. Replacing 20–30% of it with PozzoDyne™ directly lowers embodied carbon per cubic yard — without changing how concrete is produced.
Data-backed decarbonization
LCA-validated performance supports ESG and sustainability reporting, aligns with emerging low-carbon material standards, and gives project owners quantifiable impact.
Certifications & Standards
Standards-compliant by design.
PozzoDyne™ is engineered to meet established industry standards and integrate seamlessly into existing concrete specifications.
ASTM C1866 Compliance
Standard Specification for Ground-Glass Pozzolan for Use in Concrete
PozzoDyne™ complies with ASTM C1866, the established specification for ground-glass pozzolan used in concrete. Beyond compliance, its engineered fineness and strength performance exceed key minimum requirements established by the standard.
Loss on Ignition (LOI) — consistently below the ASTM C1866 maximum limit of 0.5%
Fineness — engineered particle-size distributions significantly finer than the minimum requirements of ASTM C1866
Chemical composition — meets all chemical composition requirements established under ASTM C1866
Strength activity — exceeds ASTM C1866 minimum strength activity requirements and delivers continued strength development beyond 28 days
Specification-ready for commercial and infrastructure projects — can be specified per ASTM C1866 (as a ground-glass pozzolan in concrete) & ASTM C595 (as a Portland-pozzolan cement) within performance-based specs and 20–30% replacement strategies.
