ACI Concrete Strength Testing Technician Practice Test

The report must also include information regarding the:

1. Length, pressure, and torque

2. Span length, applied load, and modulus of rupture

3. Width, depth, and weight of the specimen

4. Material, age, and size of the specimen

The correct answer is: Span length, applied load, and modulus of rupture

The required information in a concrete strength testing report is crucial for ensuring accurate assessment and interpretation of the concrete's structural integrity. Reporting span length, applied load, and modulus of rupture offers valuable insight into the concrete's performance characteristics. Span length refers to the distance between supports in a bending test, which is essential for understanding how the concrete will behave under real-world conditions. The applied load quantifies the force exerted on the specimen during testing, which directly influences the test results and indicates the load-bearing capacity of the concrete. Modulus of rupture provides a measure of the tensile strength of the concrete; this value helps in determining how well the material can withstand bending forces. Including this information helps ensure that the results can be correctly interpreted, compared to standard values, and used in further calculations related to design and safety. Accurate reporting is vital for engineers and architects to make informed decisions based on the test results, thereby ensuring structural reliability. In contrast, the other options may include relevant measurements or characteristics, but they do not encompass the essential aspects of strength testing as comprehensively or directly related to evaluating concrete performance in structural applications.
