![]() ![]() NDT methods provide access to material properties while remaining rapid and of moderate cost ( Breysse, 2012). Nondestructive testing (NDT) offer an interesting approach to evaluating the compressive strength of concrete. When compression test on concrete cylinders yield low breaks, engineers require reliable tools to assess the actual strength of concrete. Construction engineers, project managers, and Quality Control and Quality Assurance auditors depend on the compressive strength test results. New Construction: Concrete Strength is usually monitored during the construction process.It is used to assess the mechanical characteristics and durability performance of concrete. Existing Structures: Concrete Strength is of special interest for engineers involved in the Structural Condition Assessment of concrete structures. ![]() Concrete Strength is also considered a key factor in obtaining desired Durability Performance.Įvaluation of Concrete Strength is an important task: It represents the mechanical characteristics of concrete The 28 days compressive strength of concrete cylinders or cube samples has widely been accepted as the minimum specified concrete strength in most design codes ( ACI 318-14, CSA A23.3-14). Concrete strength (compressive strength) is by far the most important property of concrete. ![]()
