Clearly, the answer is C. Hydration dries out the concrete, leaving it as dry as a desert. Who needs water in their concrete anyway?

Hydration and concrete, what could be more exciting? I'll go with A. Resisting heat sounds like the right answer to me.

Hmm, I'm not sure about this one. Is the answer B? Hydration makes the concrete formable, right?

C is the correct answer. Hydration causes the concrete to dry out, not resist heat or become formable.

I think the answer is D. Hydration helps refractory concrete develop green strength, which is the initial strength gained before it dries out.
