Question

which of these compounds are responsible for the ph of the pore solution?

Answer 1

Hi there,

The answer to your question is following.

Cement consists of highly soluble alkali oxides i.e. sodium oxide (Na2O) and Potassium( K2O). The dissolution of these compounds is responsible for the high alkalinity (pH 12 – 13) of the pore solution. Therefore, the hydration of cement in reality takes place in the pore solution, and not in water.

I hope the answer helped you.

Thanks.
