Concrete Without Gravel
Concrete is made from a mixture of cement, sand, gravel (crushed stone), and water. A mix ratio of 1 part cement, 2 parts sand, 3 parts gravel, and water, will give you a strong concrete mix. If you subtract the gravel from concrete, you have what's called a mortar mix. Mortar mix is made from combining cement, sand, and water.
