Cements for Modern Concrete Construction
June 16, 1-2 pm Eastern
Presented by Eric Koehler, Ph.D, PE | Titan America
Hosted by Lionel Lemay, PE, SE, LEED AP | ConcreteNexus
The demands on concrete are increasing—from fast-track construction, ultra-flat flooring, and the need for more resilient and sustainable construction materials. This presentation describes Titan America’s TriForce Cement and how it addresses the needs of concrete producers, contractors, and specifiers. TriForce™ cement was developed in collaboration with concrete producers and contractors to address real-world challenges in concrete production and placement, including water demand, finishability, and long-term durability. By integrating multiple materials into a single engineered solution, TriForce cement delivers consistent, predictable performance while maintaining the flexibility to incorporate additional SCMs at the concrete plant.
Eric Koehler, Ph.D., P.E., will present this webinar. Koehler is the Vice President of Innovation at Titan America, a leading East Coast producer of low‑carbon cements, aggregates, and ready‑mixed concrete known for advancing sustainable, next‑generation construction materials. Eric holds his doctorate in civil engineering from the University of Texas at Austin and is a licensed Professional Engineer in Florida, Virginia, and Texas. His career spans influential roles in R&D, product development, and concrete technology, with a strong track record of pioneering innovations that elevate performance, quality, and sustainability in ready‑mixed concrete.
Concrete's Contribution to LEED v5 (On-demand)

Attendees will gain practical insights into low‑carbon mix design pathways, procurement expectations, and documentation requirements that position concrete as a high‑impact solution for LEED v5 certification. Join us to understand what’s changing, why it matters, and how producers and designers can stay ahead.
Concrete's Contribution to Envision Certification (On-Demand)
Originally aired April 14, 1-2 pm Eastern
Presented by Lionel Lemay, PE, SE, LEED AP
This webinar explores how concrete plays a pivotal role in achieving Envision certification for sustainable infrastructure. Participants will learn how responsibly sourced materials, optimized mix designs, and transparent environmental data—such as EPDs—support key Envision credit categories, from reducing embodied carbon to enhancing resilience and long‑term performance. We’ll break down practical strategies for project teams, highlight real‑world applications, and show how concrete producers can align with Envision’s goals to deliver measurable social, environmental, and economic benefits. Join us to understand concrete’s unique potential to elevate infrastructure sustainability and drive meaningful project outcomes.
Use of Mineral Fines to Reduce Carbon Emissions, Decrease Production Cost, and Improve Durability (On-Demand)
May 19, 1-2 pm Eastern
Presented by John Guynn | Roman Cement
Hosted by Lionel Lemay, PE, SE, LEED AP | ConcreteNexus
This webinar explores how precisely graded mineral fines can transform concrete performance while lowering both environmental impact and operational costs. By improving particle packing and increasing mix density, producers can significantly reduce cement content while improving strength, durability, or workability, often saving $5 to $20 per cubic yard while meaningfully shrinking their carbon footprint. Attendees will learn how this practical, field‑proven approach delivers stronger, more sustainable concrete and measurable bottom‑line benefits.
The session will be presented by John Guynn, Founder and Chief Science Officer of Roman Cement, an innovator with more than 40 U.S. and international patents related to low‑carbon concrete technologies. With decades of experience developing and testing advanced mix designs—including multiple award‑winning field trials—John brings deep technical expertise and industry leadership. He currently serves on the ACI 211‑N committee and leads a task force updating standards for proportioning with ground limestone and mineral fillers.
