Concrete testing is used for a number of purposes, including determining the structure’s efficiency, resilience, and long-term viability. These test results may be used to assess if a structure needs to be repaired or whether its integrity is adequate as is. The following is a list of testing methods that we offer to our clients, along with a brief explanation of how they work.
Rebound Hammer Testing
This test uses a tool called a Schmidt Hammer to determine the surface hardness of a concrete area. The hammer has a spring-controlled hammer head that slides on a plunger frame. The spring mechanism forces the hammer head into the concrete during testing, which then bounces back. This rebound is calculated in order to assess the surface hardness of the concrete. This quantity is correlated to the compression strength of concrete.
Drilled Cores Testing
The core test is the most direct method of determining the compressive strength of concrete in existing structures. It is a destructive test as the cores are drilled directly from concrete members. Engineers and investigators use a variety of principles and guidelines in practice. In Europe, the most commonly used ones are (EN 12504-1, 2000; EN 13791, 2007). The following are the key steps in the evaluation methodology for measuring concrete strength using cores:
– Making plans for an inquiry
– Main drilling
– Testing cores
-Recognizing and interpreting core strengths
Similar methods can be used for assessing the compressive strength of masonry structures.
Detection And Bar Diameter Estimation Of Concrete Reinforcement
The device works by detecting changes in an electromagnetic field caused by steel bars embedded in concrete. The wave transceiver travels horizontally and vertically in parallel strips on a flat surface. The built-in hardware estimates the reinforcement in the concrete, the cover thickness, and the reinforcement diameter.
