iii. Combined ultraviolet and rebound hammer test iv. Core extraction test v. Ingredient analysis test. The main aim of NDT is to assess one or more of in situ strength properties i.e. density, durability, and moisture content. NDT is the only way to assess the depth of cracks and to investigate whether any structural damage has occurred.
Civiltec Testing Services also provides concrete coring works up to 300 mm depth with core diameter of 50 mm, 75 mm, and 100 mm. Prior to any coring works, the coring area will be scanned by using rebar detector or GPR Live NDT equipments to ensure the rebar inside the concrete will not be cut during the extraction process. Concrete is cut ...

3.1. Current Egyptian Code (2008)/standard and British Code (2003) According to these codes, the estimated in-situ concrete cube strength (f cu) may be calculated from the measured compressive strength of core (f core) according to the following expression: (1) f cu = (F l / d) · (F Reinf.) f core where the factors (F l / d) and (F Reinf.) account for the effect of l/d …
3.1 This test method provides standardized procedures for obtaining and testing specimens to determine the compressive, splitting tensile, and flexural strength of in-place concrete. 3.2 Generally, test specimens are obtained when doubt exists about the ...

Test Method for Microscopical Determinøtion of Parameters of the Air-Void System in Hardened Concrete. The test was performed on one core. 1,.2.2 Seraice Life Modeling The service life modeling included tfuee subtasks, described below. Field and laboratory data were used to predict future durability performance and to propose repair options
For concrete cast against earth, such as slabs and pavements, the absorptive properties of the subgrade also affect core strength. Cores from concrete cast on subgrades that absorb water from the concrete will generally be stronger than cores from concrete cast against metal, wood, polyethylene, concrete, or wet, saturated clay. 2.2—Consolidation
