4. Lightweight concrete contains no aggregate larger than sand, lime, thermal ash, synthetic fiber, cement, aluminum powder and water as binding agent. When AAC is mixed and cast in forms, several chemical reactions take place that give AAC its light weight (20% of the weight of concrete) and thermal properties. Therefore, lightweight concrete is quite light and …
