Unlike standard concrete, aerated concrete is notably more uniform because it lacks coarse aggregates. However, despite this internal consistency, it displays a wide spectrum of performance levels. The specific characteristics of aerated concrete are dictated by its microscopic structure and chemical makeup, which are shaped by the choice of binding agents, the technique used to create air pockets, and the curing process. While it was originally valued primarily for its thermal insulation, there is a growing focus on its structural potential. This shift is driven by its low density, the reduction in raw material consumption, and its capacity to incorporate industrial byproducts, such as cast iron slag, on a massive scale. This document categorizes research into aerated concrete based on three primary pillars:
