Precision micronization

Engineered at the micron scale.

Micronization is more than reducing particle size — it’s engineering particles to maximize reactive surface area and pozzolanic activity. This precision enables higher cement replacement levels while maintaining the strength, durability, and performance demanded by modern concrete.

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.

Higher PerformanceLower Embodied CarbonReliable Local SupplyConsistent Quality
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.

Engineered reactivity. Measurable results. How PozzoDyne™ concrete outperforms conventional mixes.

01

Compressive strength

Delivers slag-like early-age performance at 7 days and significantly exceeds the control mix at 28 days through continued pozzolanic reaction.

02

Enhanced later-age strength

Continued pozzolanic reactions contribute to control-exceeding long-term strength development beyond conventional curing periods.

03

Reduced chloride permeability

A denser cement matrix limits chloride ingress, helping protect reinforcing steel from corrosion.

04

Improved sulfate resistance

Reduced calcium hydroxide and a refined pore structure improve resistance to sulfate attack in aggressive environments.

05

ASR mitigation

Consumes alkalis and refines the concrete microstructure to reduce the risk of alkali-silica reaction (ASR) expansion.

06

Stable water demand

The non-porous nature of glass minimizes water absorption, supporting stable water demand and improved consistency across concrete mix designs.

07

Extended service life

A refined and less permeable concrete matrix improves long-term durability and extends the service life of concrete structures.

08

Improved matrix densification

Ultra-fine particles fill microscopic voids, producing a denser, stronger, and more durable cementitious matrix.

09

Higher R-value (insulation)

Improved thermal performance helps regulate interior temperatures, supporting more energy-efficient buildings and lower operating costs.

10

Lower heat island effect

Lighter-colored concrete reflects more solar radiation, helping reduce surface temperatures and urban heat island effects.

11

Enhanced particle packing

Engineered particle-size distribution improves packing efficiency, reducing void space and optimizing matrix density.

12

Reduced efflorescence

Lower permeability and reduced free lime migration help minimize surface efflorescence over time.

13

Improved freeze-thaw durability

When properly air entrained, a denser concrete matrix improves resistance to freeze-thaw cycles and deicing salt exposure.

14

Improved abrasion resistance

A denser, stronger cement matrix improves resistance to surface wear and abrasion in high-traffic and demanding service environments.

15

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.

Performance-Based Validation
