Understanding the Alphabet Soup of Lightweight Cellular Concrete (LCC)
Lightweight Cellular Concrete (LCC) is the chameleon of construction materials—lightweight, adaptable, and ready to tackle a little bit of everything. Need backfilling? It’s got you covered. Thermal insulation? Easy. Structural support? Absolutely. Its secret lies in its reduced density, achieved by incorporating air or foam into its mix. Over time, this ingenious material has evolved into so many forms and formulations that it now boasts more names and acronyms than a civil engineer’s inbox on a Friday afternoon. From LCC to Flowable Fill, and everything in between, this document is here to help you navigate the glorious chaos of LCC terminology—because calling it just "Lightweight Cellular Concrete" would be too easy.
