Side by side comparison of expanded glass sand and natural sand particles for concrete mix design

Expanded Glass Sand vs. Natural Sand: Performance, Cost, and Sustainability Compared

Leave a Comment / Expanded Glass Sand /

For decades, natural sand has been the default fine aggregate in mortar, tile adhesive, and specialty concrete mixes. But as sourcing pressure, freight costs, and sustainability documentation requirements all increase at once, more producers are testing expanded glass sand as a direct alternative. Here’s how the two actually compare on the properties that matter in

Tile adhesive mortar mixed with expanded glass sand for improved spreadability and workability

How Expanded Glass Sand Improves Tile Adhesive and Mortar Workability

Leave a Comment / Expanded Glass Sand /

Workability is one of the hardest properties to engineer into a dry mortar or tile adhesive formulation. It affects how easily an installer can spread, trowel, and adjust the material on the job site — and it has a direct relationship to callbacks, labor time, and customer satisfaction. Expanded glass sand has become a popular

What Is Expanded Glass Granulate? A Guide to Lightweight Recycled Aggregate for Concrete

Leave a Comment / Expanded Glass Granule /

Concrete and CMU producers are under growing pressure to cut unit weight, document recycled content, and hold the line on compressive strength — often all at the same time. Expanded glass granulate has emerged as one of the more practical answers to that combination of demands: a lightweight, closed-cell aggregate made from 100% post-consumer recycled

Lightweight concrete deck mix using expanded glass granulate to meet ASTM C330 unit weight requirements

Expanded Glass Granulate for Lightweight Concrete: Meeting ASTM C330 Without Sacrificing Strength

Leave a Comment / Expanded Glass Granule /

Lightweight concrete for elevated decks sits at the intersection of two requirements that often pull in opposite directions: hit a target unit weight under ASTM C330, and still deliver the compressive strength the structural design calls for. Expanded glass granulate has become a practical tool for producers trying to satisfy both at once, particularly as

Rice Husk Ash in Concrete: What Ready-Mix Producers Need to Know

Leave a Comment / Ultra Fine RHA /

What Is Rice Husk Ash? Rice husk ash is a byproduct of burning rice husks — the protective outer shell of rice grains removed during milling. When rice husks are combusted under controlled conditions, the organic material burns away, leaving behind a fine ash composed predominantly of amorphous (non-crystalline) silica. That amorphous silica content is

Comparison of Re-Act 4 ultra-fine and Re-Act 4 SR slag replacement ground glass pozzolan particle size

Re-Act 4 vs. Re-Act 4 SR: Which Ground Glass Pozzolan Is Right for Your Project?

Leave a Comment / Ground Glass Pozzolan /

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

High-performance concrete data center foundation with ground glass pozzolan SCM for low GWP EPD

Why Data Center Concrete Projects Are Specifying Ground Glass Pozzolan

Leave a Comment / Ground Glass Pozzolan /

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

The Slag Replacement Grade Ground Glass Pozzolan Built for Ready-Mix Operations

Leave a Comment / Ground Glass Pozzolan /

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
