Quality control criteria for gas permeability testing of concrete structures

Abstract Curing is a crucial process during the construction phase of concrete structures, as it plays significant role in ensuring durability and strength. During curing process, kept moist to allow properly hydration hardening. This helps prevent cracking, increase concrete's compressive strength, improve its resistance weathering, abrasion, other forms wear. Therefore, essential that carried out correctly ensure longevity structural integrity structures. The pore system within critical determining various types degradation. One way assess quality by measuring gas permeability. Gas permeability measure how easily gases, such air or water vapor, can pass through concrete. If has high permeability, allows harmful substances, water, gases chemicals, penetrate into concrete, causing damage reducing over time. Herein testing used for evaluation quality.
