Question

For complete hydration to occur, an amount of water equal to ___% of the weight of the cement is required. an extra ___ to ____ or more is required to make a workable mix

Answer 1

Complete hydration of cement requires water equaling 25 to 28% of the cement's weight. An additional 15 to 20% of water is often necessary for workability of the mix.

Step-by-step explanation:

For complete hydration to occur, an amount of water equal to 25 to 28% of the weight of the cement is required. An extra 15 to 20% or more is typically needed to make a workable mix. The exact amount can vary depending on the type of cement and the desired consistency of the concrete mix. In general, too little water can lead to incomplete hydration and a weak concrete, while too much water can compromise the strength due to a higher water-to-cement ratio.
