• What is the Effect of Moisture on Cement Bag?

    Apr 24, 2016· Before we discuss the effect of moisture on cement, let us understand the chemistry of strength gain due to cement. Cement when mixed with water, undergoes a chemical reaction called hydration, due to which it hardens and acquire strength. The finer the cement, the more it hydrates (i.e. mixed with water) and more strength. Hence or when stored
