Concrete Dust Deposits

Adhesiveness of concrete dust contamination, it embeds deeply into surfaces during construction exposure. This inorganic coating forms uneven layers and thus clings to substrates like metal or stone, creating porous patterns from airborne particles settling over time. Formation occurs through mechanical abrasion and environmental settling, so contamination builds gradually and resists dislodgement. In laser cleaning applications, removal challenges arise from its dense structure, which absorbs energy unevenly and leads to incomplete ablation on rough areas. Material-specific behaviors vary; on metals, it scatters laser beams thus prolonging treatment, while on concrete bases, it merges with the host material and demands precise pulse adjustments. After irradiation, residues still persist in crevices, so post-process verification confirms surface recovery. This contamination, it demands tailored parameters for effective clearance.
