Destructive Testing - Concrete
Materials and construction in focus: analyze and evaluate with precision
Destructive Testing, DT, in concrete is a crucial service for assessing concrete strength and identifying potential damages, such as cracks and corrosion.
How is Destructive Testing, DT, conducted? To make an accurate and realistic assessment of a concrete structure, it often requires testing the properties of the concrete through various destructive tests. Testing can be performed either directly in the structure in the field or by drilling a sample from the structure for further testing in the laboratory.
DT concrete can be divided into four main areas:
- Compressive strength (SS-EN 12390-3). A compressive strength test measures the material's ability to resist compression. This test is conducted in destructive testing to assess the concrete's capability, which is crucial for understanding the overall strength and durability of the material.
- Tensile strength (SS-EN 1542, SS 137243): A common method in DT for concrete is tensile testing, where samples are taken from the concrete to measure the composition and structure. This is done by applying controlled force to the sample until it breaks, providing information about the concrete's ability to resist tensile forces.
- Adhesive strength (SS 137243, SS-EN 13892–8): Adhesion tests on reinforcement are performed by applying controlled load to a prepared reinforcement sample to measure the force required to remove it from the concrete. This insight helps understand how well the reinforcement material adheres and affects the structural strength and load-bearing capacity.
- Splitting tensile strength (SS-EN 12390-6): A test to measure the concrete's ability to resist cracking.
Concrete structures are subjected to various stresses, such as gravity loads, climatic conditions, and other external factors. These stresses lead to cracking in the concrete, which can reduce its strength and impact the functionality of the structure.
Regular inspections of concrete structures are crucial to prevent significant damage or costly repairs in the future. By conducting tests on concrete, one can ensure that construction projects achieve the highest quality and comply with applicable standards.
