In the method of voids for determination of the quantity of cement paste, it is assumed that

• Voids in coarse aggregates are filled by fine aggregates
• Voids in fine aggregates are filled by the cement paste
• Volume of fine aggregates is equal to total voids in coarse aggregates plus 10% extra
• Volume of cement paste required is equal to total volume of voids in fine aggregates plus 15% extra
• All the above.
