How Ready-Mix Producers Can Lower EPD and GWP Numbers Using the Right SCMs If you run a ready-mix operation, you’ve probably noticed a shift in the questions coming from customers. A few years ago, the conversation was almost entirely about strength, slump, and price. Today, more and more project owners — especially on data center,

The Re-Act 4 product family includes two distinct ground glass pozzolan grades — standard Re-Act 4 and Re-Act 4 SR — and the differences between them matter significantly for mix design, application selection, and project economics. If you’re evaluating ground glass pozzolan for the first time, or transitioning from slag or fly ash, understanding how
Re-Act 4 vs. Re-Act 4 SR: Which Ground Glass Pozzolan Is Right for Your Project? Read More »
Data centers represent some of the most demanding concrete specifications in modern construction. Foundations, walls, and slabs must support massive mechanical and electrical loads, resist chemical and moisture intrusion for decades, and increasingly meet strict sustainability benchmarks tied to corporate ESG commitments. Ground glass pozzolan — specifically Re-Act 4 SR — is emerging as the

Ready-mix concrete producers already running slag, Class C fly ash, or Class F fly ash are under growing pressure — from owners, architects, and general contractors — to lower the Global Warming Potential (GWP) numbers on their Environmental Product Declarations (EPDs). Re-Act 4 SR is engineered precisely for that challenge. Developed as a slag-replacement grade

Sustainable construction requires measurable reductions in carbon intensity. Ground Glass Pozzolan supports this objective by lowering cement content in concrete mixtures. Because cement production accounts for significant emissions, partial replacement directly reduces embodied carbon. Beyond carbon reduction, recycled glass utilization strengthens circular economy initiatives. Municipal recycling programs often generate excess glass that lacks market demand.

Infrastructure concrete must resist freeze-thaw cycles, moisture intrusion, and chemical exposure. Ground Glass Pozzolan improves long-term durability by refining the internal pore structure of concrete. Its pozzolanic reaction consumes calcium hydroxide and forms additional binding compounds. This reaction reduces capillary porosity and improves resistance to chloride penetration. For highway pavements and marine structures, this protection

Why Ground Glass Pozzolan Is Gaining Attention in Modern Specifications Ground Glass Pozzolan is increasingly being specified in performance-based concrete standards. Engineers are shifting away from prescriptive mix designs and toward measurable durability outcomes. In this context, finely processed recycled glass offers reliable pozzolanic performance while supporting sustainability targets. Unlike conventional supplementary materials, Ground Glass

Introduction Modern construction demands materials that are both strong and sustainable. One of the best innovations in this field is ground glass pozzolan (GGP). Let’s explore five major benefits of using GGP in your concrete mix design. 1. Sustainability and Waste Reduction Each ton of GGP diverts glass from landfills. This directly reduces waste and

Introduction Concrete is one of the most used materials in the world — but it also contributes nearly 8% of global CO₂ emissions. To make construction more sustainable, engineers are turning to ground glass pozzolan (GGP). This innovative material transforms waste glass into a high-performance cement replacement that’s better for the planet and stronger for
