Abstract: COLORED WATER-BASED DESTRUCTIVE TEST FOR ABSORPTION IN AAC DEBRIS CONCRETE The invention discloses a novel method for evaluating water absorption in concrete specimens prepared with coarse aggregates partially or fully substituted with debris of autoclaved aerated concrete (AAC) blocks. Conventional sorptivity and oven-based absorption tests provide only numerical values without visual evidence of penetration depth. The proposed method introduces the use of pigmented water, combined with destructive slicing of concrete cubes into layers of 5–15 mm thickness. This enables direct visual observation of capillary action, void distribution, and impregnation depth within the specimen. Experimental results demonstrate that specimens with 25% AAC debris replacement exhibit absorption behavior closest to standard concrete, while higher replacement levels show deeper penetration. The invention provides both quantitative and qualitative assessment of water absorption, offering improved accuracy, sustainability through waste utilization, and applicability to high-performance and eco-friendly construction practices.
