🌍 Big Step Forward for Geopolymers: ASTM C1948–24 Standard Released
We’re excited to share that ASTM International has officially published ASTM C1948–24: Standard Specification for Geopolymer Binders. This marks a historic milestone for the construction materials sector—and for the commercialization of geopolymers worldwide.
Until now, the lack of standardized specifications has been one of the biggest barriers to mainstream adoption. With ASTM C1948–24, industry stakeholders finally have a recognized framework to evaluate performance, safety, and compliance of geopolymer binders.
For Geopolymer International, this standard validates years of innovation and field work. It accelerates pathways for:
✅ Utility infrastructure—where our binder has already seen commercial use.
✅ Fireproofing and resilience applications—addressing urgent challenges from wildfires to structural safety.
✅ Future scaling—opening new doors for global partnerships, certifications, and regulatory approvals.
This isn’t just about one company or one material—it’s about giving the world a practical, high-performance alternative to Portland cement, a major contributor to global CO₂ emissions.
📢 We see this standard as a call to action: for utilities, regulators, and developers to join in advancing sustainable, resilient infrastructure.
👉 What opportunities do you see for geopolymer adoption now that ASTM has set the standard?
