Water Absorption and Damage . Crushed concrete is more porous than new concrete, which means it has a higher water absorption rate. This can lead to issues with moisture damage over time, especially in areas. prone to heavy rainfall or freezing temperatures, where water can seep in, freeze, and cause cracking or shifting. Comparison with Other ...

Water absorption emerged as a key parameter for evaluating the purity and quality of these materials. The statistical analysis revealed that when the water absorption of recycled aggregates and sand falls below 5%, the compressive strength may, at most, decrease by 15% (97.5% confidence) at any replacement level.
