CONCRETE VS MORTAR
What’s the difference between “cement,” “concrete” and “mortar”? The terms refer to substances that
have three distinct purposes:
Cement: The binding element in both concrete and mortar.
Concrete: A product composed of cement, sand and gravel or other coarse aggregate. When water is mixed in with this product, it activates the cement, which is the element responsible for binding the mix together to form one solid object.
Mortar: A product composed of cement and sand. When water is mixed in with this product, the cement is activated. Whereas concrete can stand alone, mortar is used to hold together bricks, stones or other components.
How dense is wet concrete? Concrete and mortar both have a density of about 2 to 2.1 tons per cubic meter. This figure applies both to wet and cured material. There are special lightweight concretes as low as 1.4 t/cu m.
