Portland Cement Concrete

For complete hydration of Portland cement, only about 40% water is needed. If a W/C ratio greater than about 0.40 is used, the excess water not needed for cement hydration remains in the capillary pores or evaporates. If a W/C ratio less than about 0.40 is used, some cement particles will remain unhydrated. 13.1.1 Types of cement
