Question 1193857
.


The volumes of the mixtures are given in the post.


The components are not a concrete.

Even the sum of components is not concrete yet.


To get a concrete, water must added in some proportion and the mixture should be stirred carefully.


Then some physical and chemical processes take place in the mixture (like baking bread).


The result of this technological process is concrete.


Resulting volume of concrete is not equal the sum of volumes of components.



About physical and chemical processes of getting concrete read and learn from links below

The way to estimate the volume of the concrete having given the masses of components and water

is to divide the total mass of components (including water) by the density of concrete.
