Reuse of Aerated Autoclaved Concrete Waste as a New Material in Shallow Soil Stabilization

Nowadays, the autoclaved aerated concrete (AAC) is one of the most widely used construction materials. Hence, there will be a huge amount of AAC waste in the near future. In this research, an experimental research study within the scope of investigating the potential use of autoclaved aerated concrete (AAC) waste in the shallow soil stabilization was presented. Three types of subgrades that are a high plasticity bentonite clay (CH), a low plasticity clay (CL) and a sand (SP) were used with the pulverized autoclaved aerated concrete waste (PAACW). It was found that PAACW additive increased the unconfined compression strength and CBR of the clay soils and the internal friction angle of the sand. Also, addition of PAACW significantly decreased the swelling potential and swelling pressure of CH
