Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFApproximately 23% water by weight is required for complete hydration i.e to complete all chemical reactions and 15% water is entrapped in between the voids of cement. The total water required for complete hydration and workability is 38% by weight.
∴ water required to complete all chemical reaction in cement is 23 %
Note:
The water required for completing chemical reaction is 23 %
A total of 38% water by weight of cement is required to complete the chemical reaction and fill the space within the gel pores.
