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 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
