the organizers project has studied the features and components of the cement used in construction
as well as lessons in chemistry have discussed the properties of some substances, such as. aluminum oxide or
alumina (AL2O2), calcium oxide, or lime (CaO), a component found in. Clay and shells Through the autoclave, respectively,
from the preparation of such conditions, so the concept and create a project by using the material is reluctant to use the qualifying standard is similar cement shells and clay. The cement
then check the product was compared with standard cement on the mass. The duration of erection Shock Resistant Changes acid - base In order to draw conclusions about the quality of products in the primary.
