What is DIN EN 12390-7:2019?

DIN EN 12390-7:2019 is a technical standard that specifies the test method to determine the compressive strength of hardened concrete using portions of concrete taken from structures for investigation purposes.

of DIN EN 12390-7:2019

The standard provides a comprehensive set of guidelines and procedures to accurately evaluate the compressive strength of concrete. It is widely used by engineers, architects, and construction professionals for quality control, inspection, and forensic purposes.

The tests specified in DIN EN 12390-7:2019 are performed on cylindrical specimens extracted from existing structures. These samples provide valuable information about the structural integrity and load-bearing capacity of the concrete under investigation.

Test Procedures

DIN EN 12390-7:2019 outlines the detailed steps involved in testing concrete specimens for compressive strength. The procedure includes carefully extracting cylindrical cores from the structure, ensuring proper handling and preparation of the samples, and testing them under controlled laboratory conditions.

The testing process involves subjecting the concrete specimens to gradually increasing axial compressive forces until failure occurs. The maximum force sustained by the specimen before failure is recorded as the compressive strength. This test provides valuable data regarding the quality, durability, and performance of the concrete being investigated.

Significance in Concrete Investigations

DIN EN 12390-7:2019 plays a crucial role in concrete investigations and forensic analysis. By accurately determining the compressive strength of concrete, this standard helps assess the structural health, identify potential defects or damages, and develop appropriate repair strategies.

Concrete structures subjected to various environmental conditions and loading scenarios may undergo changes over time. The compressive strength test specified in DIN EN 12390-7:2019 enables experts to evaluate the condition and performance of concrete in existing structures, contributing to the overall safety and longevity of buildings and infrastructures.

Overall, DIN EN 12390-7:2019 provides the industry with an internationally recognized standard for evaluating the compressive strength of hardened concrete. By adhering to this technical guideline, professionals can ensure accurate and reliable assessment of concrete properties, leading to improved quality control, maintenance strategies, and overall structural safety.
