Challenge Problems
Push your limits with advanced challenges
If a concrete beam has a compressive strength of 35 MPa and a flexural strength of 5 MPa, analyze its suitability for a parking garage structure subjected to 20 MPa compressive and 3 MPa bending loads.
💡 Hint: Compare the actual loads against the strengths provided.
Given a concrete mix design with a water permeability of 3.5 x 10^(-10) m/s, determine whether this mix would be suitable for use in a marine environment.
💡 Hint: Consider typical permeability values for marine applications.
