how to find specific gravity of silica fume formula

Specific Gravity of Cement

So if the specific gravity of any substance is known to us we can use the materials in suitable place of any work Basically specific gravity defines that the substance is how much heavier than water or reference substance of the same volume The specific gravity of cement ranging from 3 1 to 3 16 g/cc By this statement we can ensure that cement 3 1-3 16 times heavier than water of

How to Calculate Silicon From Silica

Determine the molecular mass of silica by adding together the atomic masses of all the elements in a molecule of silica Silica has the formula SiO2 which in chemical terms means that each molecule is composed of one silicon atom bonded to two oxygen atoms Your calculation should then be: 28 0855 (Si) + (15 9994 (O) x 2) = 60 084
