Concrete Core Testing

sptc testing & engineering title shadow

The concrete cube test, or concrete prism test, is a way to measure the strength of concrete and hence determine its grade. Usually, this is done for the purposes of quality control during the construction of new structures. In contrast, the concrete core test is used to determine the grade of concrete in existing structures, often as one part of the overall safety check on an existing structure.

While the concrete cube/prism test is used to measure the grade of concrete after a specific length of curing, the concrete core test method provides standardized procedures for obtaining and testing specimens to determine the compressive, splitting tensile, and flexural strength of in-place concrete.
Concrete Cube Compressive Strength. EN 12390-3,
ГОСТ 10180 (GOST 10180)
Determines the strength of hardened 100 - 150mm concrete cubes usually at 7, 14 and 28 days after casting. Used as quality control during construction of concrete structures.
Concrete Core Compressive Strength. EN 12504-1,
ГОСТ 28570 (GOST 28570)
Used to assess the strength of concrete in existing structures.
