You are constructing a foundation on volcanic soil with high sulfate content. The soil test shows sulfate concentration of 2,800 ppm. What type of cement should be specified?
Correct Answer
D) Type V Portland cement
With sulfate concentration above 2,000 ppm, Type V sulfate-resistant cement is required to prevent sulfate attack on the concrete foundation.
Why This Is the Correct Answer
With sulfate concentration above 2,000 ppm, Type V sulfate-resistant cement is required to prevent sulfate attack on the concrete foundation.
