Key takeaways Foamed concrete is a lightweight cellular concrete with intentionally entrained air voids. It belongs to the cellular concrete family alongside autoclaved aerated concrete (AAC). The classification is based on its porous structure and low density. Foamed concrete is produced by mixing cementitious materials with a preformed foam. It offers thermal insulation, sound absorption, …
Key takeaways Foamed concrete density typically ranges from 300 to 1,900 kg/m³, controlled by foam volume. Low-density (300–600 kg/m³) excels in thermal insulation and void filling. Medium-density (600–1,200 kg/m³) balances strength and insulation for partition walls and blocks. High-density (1,200–1,900 kg/m³) provides structural strength for load-bearing elements. Density directly influences compressive strength, thermal conductivity, and …
Are Your Lightweight Concrete Batches Failing? You Are Not Alone Have you ever watched a pour of lightweight concrete collapse into a dense, heavy slab? Do your foam concrete blocks look more like Swiss cheese than uniform cellular structures? You have wasted material, time, and money. The culprit is almost always the foaming agent. Selecting …
Have You Ever Stared at a Foam Concrete Project and Felt Stuck? You have a lightweight fill job. Or maybe a roof insulation project. The specs call for a specific density—say, 600 kg/m³ or 400 kg/m³. Your crew is ready. But the equipment? That’s the wall you keep hitting. Cellular concrete blocks for lightweight fill …
