when water is added to the cement,cement volume decreases due to removal of air from cement particles. this reduction in cement volume is the bulkage
volume of 1 cement bag is 0.035cu.m.
The volume is(1000)/(density of cement in kg/m3) cubic meters.
as unit weight of cement varies from 830kg/cu.m-1650kg/cu.m volume of cement of 50 kg. varies 0.060241cu.m to 0.030303cu.m if the cement is port-land cement unit weight would be 1440kg/cu.m then the volume would be 0.034472 cu.m
Volume of One bag of cement =1.25cft =1.25x30cmx30cmx30cm=33.75 cub.cm. Density of One bag of cement =50Kg/1.25cft=40Kg/cft=40/30x30x30 =0.00148gm/cm
Gel is the hydrated cement while space is volume occupied by hydrated cement+capillary pores. Hence gel/space ratio is the fraction of volume occupied by hydrated cement in the total space occupied by hydrated cement and capillary pores

1 94-pound bag of cement is approximately equal to 1 cubic foot.
using a cubic ruler
Sand / cement ratio = 3 , that means: 1 part of cement to 3 parts of sand by volume , with sufficient water to get workable mixture.
Soundness of cement is the property of hardened cement paste undergoing large change in volume after setting without delayed destructive expansion. This destructive expansion is caused by excessive amounts of free lime or magnesia. This change in volume may cause crack and disintegration of concrete.Soundness of cement can be checked by using Le-Chatliers apparatus.
